Global Water Scarcity Impacts All

Water Scarcity Is A Global Concern
Water scarcity is a global concern, and that means there's even a problem in our own backyard.
While it may be difficult to put yourself in the shoes of an African child struggling to find fresh
water, it's important to understand that water scarcity affects everyone, even here in the United
States. Water covers approximately seventy percent of the Earth surface, but less than one percent of
that is available for human use. The world must share this small amount for agricultural, domestic,
commercial industrial and environment needs. Across the globe, water consumption has tripled in
the last fifty years. Managing the supply and availability of water is one of the most critical natural
resource issues facing the United States and ... Show more content on Helpwriting.net ...

there was a heavy runoff of water causing deficiency in water supply. Irrigation is a method of
transporting water to crops in order to maximize the amount of crops produced. Many of the
irrigation systems in place do not use the water in the most efficient way. This causes more water
than necessary to be used or not enough water to ensure healthy crops. Tom Vilsack, U.S. agriculture

Water Changes In Madagascar
Introduction Madagascar is a famous colorful cartoon movie for all kids since many years. It is a
peaceful green island with the most beautiful mixture of lots of plants and all types of animals are
found and nowhere else in the world does it show more than in the movie. Of course, many people
perhaps think this African island should is pure paradise. The reality is way different from what the
movie portrays. Around 50% of the full population lives below poverty level according to a UNDP
Human development poverty indicator. This country is entirely dependent on agriculture. Of course,
water plays a leading role in our daily life. Climate change and global warming in the recent years
are becoming serious issues which Madagascar faces today, ... Show more content on

We endorse safety at work for both the workers and the individuals who will benefit from the new
source of water. Many of the drillers on this unit have skills in hang dug wells. However, they are
working with modern, small–scale rigs provided by donors. These, machines can dig to around 150–
200 feet. The machinery is very efficient and in this zoning of Madagascar will do a great job. They
can be moved with ease and allow work to happen instantly. While the machines drill through dirt
and rock, casing is installed to keep the hole from collapsing. The next step is a concrete base is
constructed around the small casing (a few feet in diameter) and is left to set up from night to
morning. Once the concrete pad is dry, the pump instrument is correctly lowered into the hole and a
hand pump is linked. The unit prepares notes of how much water discharges and safeguards if it is
safe to drink. Due to these new wells being closed airtight, the water stays clean and can be depleted
without any

Effects Of Pesticides On The Environment
Over two–thirds of the plant (planet I assume?) is covered by it, and humans will die within 3 to 7
days without it. Water is the most precious resource on the planet, but can also be taken for granted
especially in first–world countries where it is always available at the faucet. This modern marvel of
having clean water so easily accessible is threatened by another modern invention, the application of
pesticides. While pesticides have narrowed the gap between actual yield and yield potential in our
conventional crops, they are also a source of nontarget poisoning responsible for fish kills,
reproductive failures in birds, and human illnesses (Arias–Estevez et al, 2007). In fact, only about
0.1% of pesticides actually reach their targeted pest (Pimentel, 1995). Most pesticide ends up in the
environment where it is transported or degraded through volatilization, runoff into surface water and
groundwater, or taken up by nontarget organisms (van der Werf, 1996). The movement of pesticides
into groundwater poses a grave threat to the health of our communities. According to a 1999 USGS
survey, around 50% of water samples collected from wells contained at least one pesticide (Arias–
Estevez et al, 2007). In Ohio, a well testing program started by the Water Quality Laboratory of
Heidelberg College found that wells were contaminated most frequently by atrazine and alachlor,
albeit at very low levels and in less than 5% of wells (Baker, 1990). There is a need to identify

Groundwater Analysis : Groundwater Governance
This paper reviews the available groundwater governance literature with the specific aim of
highlighting and critically examining the role of knowledge in supporting "good governance" of
groundwater resources including how knowledge co–generation/co–production may contribute to
enhancing cooperation/reducing conflict over managing shared resources. While reviews of global
literature do exist, they have thus far only been used to make generic recommendations on the
importance of knowledge for groundwater governance, and have not been specifically examined the
role of knowledge in conflict management between different actors.
Governance is essentially a set of enabling framework and guiding principles through which
institutions or set of institutions would exercise an authority. In short it shows how the decision
making of this entity is taking place and how these decisions are implemented (Rogers et. al, 2006).
The "good" groundwater governance could be described by the transparency of the decision–making
process and its further effective implementation in meeting the sustainable and equitable
management of these resources. Although groundwater governance builds onto overall water
governance, the peculiarities of groundwater and the way in which it is formed, developed and
exploited by different stakeholders requires specific governance principles and analysis (Paul,
2015).
Often environmental issues need interdisciplinary approaches and analysis which may not be
possible

The Floridan Aquifer
The Floridan Aquifer
Water is an endless cycle that repeats itself but doesn't necessarily remain drinkable. Rain feeds
vegetation, evaporation occurs, and then returns to rivers, streams, and lakes and may seep into
rocks and caves underground through limestone and into aquifers. It may take many years before it
reaches the surface. Water is a valuable resource that people tend to mishandle and take for granted.
Explorers have dove into the paths underground to trace paths of water that flow deep under homes,
streets, cities, and pastures only to surface a dirty and contaminated pond. Inside these deep paths
explorers have found tires, oil barrels and chemical containers that most people are unaware of.

Homeowners that water grass may require large amounts of fertilizer that contribute to high levels of
nitrates in the aquifer, a major source of drinking water. Water containing nitrates contribute to algae
growth and can endanger plants and wildlife in the springs. Lawns with landscaping with non–
native plants may also require daily watering and frequent pesticides to keep them healthy and
disease–free. Nearly half of all water withdrawn for our supply is used only to water lawns and
landscaping. Population increase in Florida has led to more to transforming rural areas and
uninhabited land into housing, shopping centers, and buildings. Pavement and roads prevent
rainwater absorption into the aquifer and increase run–off of chemicals and other waste. Agriculture
also requires chemicals to kill insects and thus absorbed into the ground into our drinking water.
Dairy farms produce a lot of animal waste along with the pesticides and chemicals used to maintain
the livestock and irrigation that also enter our supply of drinking water. BMP, or best management
practices, include water conservation. Humans have a major impact on water contamination and
should use caution so that our water is preserves. Contribution efforts on our part are reducing the

Review of Article on Arsenic Crisis in Bangladesh
Summary: The people of Bangladesh were dying and getting ill from water. This water was
provided through tube wells that were connected to an underground aquifer. Such actions were taken
on the 1980's, when many children died from diarrhea. This project facilitated the lives of many
since their people did not have to walk long distances and carry heavy jars full of water.
Unfortunately, the water was not checked for arsenic. A dermatologist believed the water from the
tube wells contained arsenic but the British Geological Survey insisted it was safe. Today the
tubewells are known to have 50 micrograms of arsenic per liter. The article also explains some of
the symptoms that could be experienced after 10 years of consuming arsenic contaminated water,
these include: black spots, conjunctivitis, bronchitis, diarrhea, etc. The Bangladesh government
borrowed money but has not yet taken action since they do not know how to solve this issue. The
Bangladesh Rural Advancement Committee trained 160 volunteers to test the tubewells and identify
the symptoms of arsenicosis. Many of their volunteers also made maps to inform people of safe
tubewells and ponds. 1. What was the purpose or point in writing this article? This article was
written to inform people of the hardships poor countries face and to encourage us to be more
involved in issues that concern our health. In the article, The British Geological Survey reassure the
villagers that their water was safe, however, the water

Hydrologic Cycle Essay
HYDROLOGIC CYCLE The hydrologic cycle is a constant movement of water above, on, and
below the earth's surface. It is a cycle that replenishes ground water supplies. It begins as water
vaporizes into the atmosphere from vegetation, soil, lakes, rivers, snowfields and oceans–a process
called evapotranspiration. As the water vapor rises it condenses to form clouds that return water to
the land through precipitation: rain, snow, or hail. Precipitation falls on the earth and either
percolates into the soil or flows across the ground. Usually it does both. When precipitation
percolates into the soil it is called infiltration when it flows across the ground it is called surface run
off. The amount of precipitation that infiltrates, versus the ... Show more content on Helpwriting.net

The voids are spaces between grains of sand, or cracks in dense rock. All water beneath the land
surface occurs within such void space sand is referred to as underground or subsurface water.
Subsurface water occurs in two different zones. One zone, located immediately beneath the land
surface in most areas, contains both water and air in the voids. This zone is referred to as the
unsaturated zone. Other names for the unsaturated zone are zone of aeration and vadose zone. The
unsaturated zone is almost always underlain by a second zone in which all voids are full of water.
This zone is defined as the saturated zone. Water in the saturated zone is referred to as ground water
and is the only subsurface water available to supply wells and springs. Water table is often misused
as a synonym for ground water. However, the water table is actually the boundary between the
unsaturated and saturated zones. It represents the upper surface of the ground water. Technically
speaking, it is the level at which the hydraulic pressure is equal to atmospheric pressure. The water
level found in unused wells is often the same level as the water table. AQUIFERS An aquifer is a
saturated geologic formation that will yield a usable quantity of water to a well or spring. Ground
water occurs in aquifers under two conditions: confined and unconfined. A confined aquifer is
overlain by a confining bed, such as an impermeable layer of clay

Human Impact On The Water Cycle
1. What are the most considerable impacts that you make? Some of the biggest impacts that humans
make on the water cycle are direct, indirect, cumulative, and induced impacts. A direct impact would
be the fact that we rely on the consumption of fresh water for sustenance and maintaining personal
hygiene. An indirect impact would be that our food is grown using chemical inputs, (including
"natural" chemicals & fertilizers), which results in the discharge of chemicals and nutrients that
leach into groundwater, and underground aquifers. A cumulative impact would be the combined
impact of our past, present, and future on the environment. And lastly an induced impact, such as a
lake that increases in toxicity due to a landfill that was created. With this in mind, the most
considerable impacts that I personally make would be; i.) The direct impact from consuming water
(retrieved from a fresh water supply – usually sourced from underground aquifers, or natural fresh
water springs.) ii.) The indirect impact from consuming electricity (15% of which is sourced from
hydroelectric dams in the state of California.) iii.) The cumulative impact of the total amount of
water that I have used, use now, and will need to sue in the future. And, iv.) The amount of water
depletion from those underground aquifers and fresh water supplies due to the aforementioned
impacts.

Analysis: Why California Groundwater Should Be Regulated
Why California Groundwater Should be Regulated
We have all heard that the drought in California is finally over but, if history repeats itself, we know
that it will be back sooner rather than later. The drought has taught us how Groundwater is used and
who uses the most. Groundwater is water from below Earth's surface that fills empty spaces and
cracks in the rock. 30 million Californians rely on groundwater for their drinking water supply.
One of the biggest consumers of groundwater in our state are farmers. During a drought the farmers
have to use wells to water their crops. The water from these wells use garoundwater from Aquifers.
Water in Aquifers provide 60% of California's groundwater in drought years. Because California has
been in a drought for the last 5 years, farmers have used and over used groundwater from wells.

33% of groundwater is supplied to households and businesses. Everyone in California uses
groundwater for drinking, cleaning, laundry, bathing and cooking. Without it we couldn't survive.
Water on Earth is a finite source. Protecting and regulating groundwater means protecting our lives.
I know that in the pas California has not been monitoring or regulating pumped groundwater. But, in
September 2014 in an article written by Melanie Mason of the Los Angeles Times, "Gov. Jerry
Brown signs historic groundwater managmenet legislation" she wrote, "Governor Jerry Brown
signed a trio of bills Tuesday establishing a framework for statewide regulation of California's
underground water sources, marking the first time in the state's history that groundwater will be
managed on a large scale.
This is good news and will help but sources say it will take 50+ years to replenish our Aquifers.
There are things we could all do to help conserve groundwater and give the Aquifers a chance to fill

Aquifer Depletion
The High Plains Aquifer encompasses approximately 174,000 square miles and stretches from Texas
to South Dakota (Fig. 1). This aquifer is also known as the Ogallala Aquifer due to the geologic
formation that it lies above. The development of this aquifer along with glacial till produced through
the retreat of glaciers during previous ice ages, has yielded a very productive region for farming.
The High Plains Aquifer is a valuable natural resource for farmers within the area, but several
factors have caused the depletion of this aquifer. Some of the factors that have caused the depletion
include a slow rate of recharge, the overlying formation, and heavy pumping within the aquifer. For
an aquifer to recharge quickly, the overlying formation must consist of a permeable and porous
lithologic unit. These rock units will allow for water to easily pass through them and into the
underlying aquifer for storage. Much of the sediment that makes up the aquifer consists of sand, silt,
and gravel that were derived from runoff of the Rocky Mountains. Recharge is from precipitation,
infiltration, and groundwater flow through the porous and permeable overlying lithologic unit to the
aquifer. The High Plains Aquifer is situated within a semiarid climate producing a slower rate of
recharge. Much of the Ogallala is located within an ... Show more content on Helpwriting.net ...
The Ogallala Aquifer also supplies millions of people in the Midwest drinking water, so the
depletion of this natural resource would have dire consequences. As advances in technology
progress, a change in the genetics of the crops within the High Plains might result in a plant that
requires a smaller amount of water to flourish. These technologic advances and environmentally
friendly practices could have drastic, positive effects on the groundwater storage within the Ogallala

Population Growth in South Florida and Salt Water Intrusion
Introduction
Rapid population growth in South Florida has significantly increased the demand for water and the
strain on the fresh groundwater supplies has triggered more saltwater intrusion to the Biscayne
aquifer. Saltwater intrusion has been one the main contaminant that continues to endanger the
Biscayne aquifer. It has occurred as a result of the followings: the over–pumping by wells, the
construction of drainage canals, and the lowering of the water table by drought. Ongoing efforts by
South Florida water agencies to protect the aquifer from saltwater intrusion include groundwater
monitoring, water management and conservation.
The Biscayne Aquifer
An aquifer is defined as underground layers of rock saturated with water that can be brought to the
surface through natural springs or by pumping. Named after Biscayne Bay, the Biscayne aquifer is a
coastal, unconfined aquifer because its top portion is the water table and it merges with the floor of
Biscayne Bay and the Atlantic Ocean. Underlies an area of approximately 4000 square miles, the
Biscayne aquifer's maps out from the southern tip of the state northwest along a wavy line to south
Palm Beach County. The cross–section of the aquifer resembles a wedge and its gets deeper as it
gets closer to the eastern coast. The Biscayne aquifer is the primary source of freshwater to most of
South Florida (Dade, Broward and part of Palm Beach counties). Furthermore, water from the
aquifer is pumped through pipeline to the

High Plains Aquifer
The High Plains aquifer was formed from erosion and transporting materials of sands, clay, and
gravel from the Rocky Mountains from stream flows. This aquifer provides water for uses of
irrigation and drinking water for eight of the fifty states which are South Dakota, Texas, Nebraska,
Colorado, Oklahoma, New Mexico, Kansas, and Wyoming. Since this aquifer spans over a vast area,
it is considered the largest in the United States. Also, because this aquifer passes through eight
different states, each state has a different policy about how each said state should handle the
conservation of the ground water that provides water to nearly 2.3 million people, and because it
covers such a large area over agricultural land, most of the water is used in irrigating the crops for
30 percent of the United States (Dennehy, 2013). The discrepancies between the eight states the
aquifer overlies causes huge problems involving the depletion of the groundwater source if certain
measures are not taken to sustain the livelihood of The High Plains Aquifer (Mann, 2009).
The High Plains Aquifer's main source of recharging comes from precipitation at a low rate below
.30 inches in parts of Texas, but over 5 inches in some parts of the other eight states within the

Nubain Aquifer: Questions
ummary and reasoning behind questions In this article Nubian Aquifer is talked about, along with
the experiments that were conducted using uncommon isotopes in attempts to uncover the mysteries

supply that traverses underground in the Sahara Desert and stretches all the way to North Eastern
Africa. Although the Nubain Aquifer happens to be one of the oldest water supplies in the world, it

questions have arisen about the Nubain Aquifer primarily because the passage of water persists to
flourish even after having been around for such a long time. Experiments Physicists conduct
experiments in relation to the Nubain Aquifer by using a rare radioactive isotope called Krypton 81.

However, the previously used isotope gave incorrect results when I came to the Aquifer. Up until

for the physicists involved to be able accomplish such a feat. The slowing of atoms was made
possible by using "the same laser–based techniques that were pioneered by the current energy
secretary, Steven Chu, in the 1980s...." This was done by using "lasers to pinpoint the frequency at
which atoms oscillate. When Krypton 81 atoms go through a laser attuned to them, they glow

Groundwater samples were collected and reported by Sultan et al. (2011) from Sinai for isotopic
analyses of H and O from open and productive wells tapping three types of aquifers: (1) fractured
basement, (2) Nubian Sandstone unconfined aquifer cropping out at the foothills of the basement
outcrops, and (3) alluvial. They believed that the unconfined and alluvial aquifers fed by a fractured
basement aquifer through discharging into the overlying sediments. The δD and δ18O isotopic
compositions of the groundwater samples from the unconfined Nubian Sandstone aquifers in the
recharge areas cropping out at the foothills of the basement outcrops are somewhat depleted (δD: –
22.7 to –32.8‰; δ18O: –4.47 to –5.22‰) compared to those from fractured basement outcrops (δD:
–19.9 to –23.2‰; δ18O: –3.77 to –5.05‰) and those from alluvial aquifers (δD: –22.7 to –23.4‰;
δ18O: –4.53 to –5.01‰), but they are less depleted than those reported from the Gulf of Suez
(Sturchio et al., 1996). The isotopic compositions of the samples from the fractured basement and
alluvial aquifers are similar to those of average modern precipitation from Al Arish and Rafah (Fig.
3). The unconfined aquifer shows a mixing between fossil waters of the Western Desert, formed in
pluvial period, and modern precipitation deposited in dry and warm climatic conditions (Sultan et
al., 1997, 2011).

In the scholarly article "Offshore Aquifers" by Renee Martin–Nagle, she discusses the discovery of
fresh water sources being found in the ocean. Nagle talks about the water shortage not only are an
issue for California, but also the entire world. She talks about how there are two different types of
aquifers, recharging and non–recharging aquifers. Recharging aquifers are aquifers are linked with
the surface and receive its water reserves from rainwater, streams, rivers, and runoff. They are
commonly found close to the surface. They are more susceptible to over–use and pollution. Non–
recharging aquifers are usually found deep beneath the surface, and porous rocks, buried beneath a
solid layer of sedimentary limestone or dolomite rock. The water found in the non–recharging
aquifers arrives there because it gets trapped there when tectonic plates shift, and sea levels where
much lower 20,000 years ago when the Siberian land bridge allowed humans to travel from Asia to
the Americas. Nagle also discussed both pro's and con's of extracting the water from the ocean. It
will not be an easy task because while the United States is fighting a water shortage, attempting to
mine the water from the ocean could cause huge irreversible damage to the ecosystem of the ocean
and pollution to the environment. If the drilling is not done very carefully, the entire water supply
could be contaminated. Nagle discusses that the underwater drilling would be comparable to drilling

The Distribution And Mobilization Of A Groundwater Aquifer
Geochemistry plays an important role the distribution and mobilization of As in groundwater
aquifer. To find the influence of geochemical processes of As mobilization in groundwater of the
study area, the correlation matrix among As and various physio–chemical parameter are given in
Table 4. Pearson correlation matrices show that various physio–chemical parameters pairs of
groundwater samples have a significant positive correlations such as TDS–EC (r = 1.000), TDS–Na
(r = 0.587), TDS–Ca (r = 0.624), EC– Na (r = 0.617), EC–Ca (r = 0.618), Na–Ca (r = 0.564), and K–
Mn (r = 0.566) respectively. Similarly some pairs have also shown significant negative correlation
such as Mg2+–HCO3– (r = 0.590), well depth–Mn (r = 0.518). The concentration of As in
groundwater has insignificantly negative correlated to Fe (r=–0.260), Cl– (r=–0.081) and SO42–
(r=–0.062), while As has insignificantly positive correlated to Mn (r=0.185), NO3–( r=0.111),
HCO3– (r=1777), pH (r=0.226), Na+ (r=0.223), K+ (r=0.227), Ca2+ (r=0.262) and Mg2+ (r=0.199).
In this study, an insignificant positive correlation between As and Mn has observed, while an
insignificant negative correlation between As and Fe has existed in groundwater aquifer (Table 4).
This finding is in good agreement with the earlier correlation matrix analysis of arsenic by Ohno et
al. (2005) and Reza and Jean (2012) in the fine–grained core sediment samples in northwestern

One of the key factors in solving the problem would be to put in place much stricter regulations for
companies to follow. If the government made companies work in a more responsible they would
have to pay more attention to where they are drilling, leading to less drilling sites in neighborhoods
or close to people's homes. The regulations on zoning could cause a chain reaction of problem
solvers, if the fracking wells start to be farther away from homes the water that people are drinking
will less likely be contaminated. For Oklahoma there are not yet regulations on where to frack like
other states. Drilling is taking place on what is called "basement" rock, this is believed to be the
cause of the tremblors. This is just one place where a little change in law can be a big change for a
community. Another easy solution would be regulating the chemicals companies are allowed to use,
the chemical cocktails used are commonly filled with acids, detergents and poisons that are not
regulated by federal laws. Natalie Starkey, a writer for The Guardian, writes to explain that even
areas that are not prone to earthquakes may still experience them due to drilling. Companies have
denied having any ties to the rising number of quakes. The earthquakes that will appear will be very
dangerous in most cases. The lack of regulation can be tied back into this issue since there are no
laws on where companies can

surface water (i.e. in the form of stormwater, treated effluent etc) within aquifers. This process is

It is also proposed to locate an MAR 2km from the coast roughly in the middle of the study area.
This MAR will inject tertiary treated sewage water into all three aquifers to prevent salinity
intrusion that is occurring in that vicinity.
As discussed above, we have an initial water balance from a previous study of the Study Area, and
we have some new parameters to enter into our assessment, namely the proposal to extract 2 ML/d
from the reservoir, and 5 ML/d from the river.
We must also note that the proposed MAR does not specify how much water would be injected, and
the proposed permits assessed below do not stipulate the quality of water required. If the permits
below require high quality water, (i.e. better than tertiary treated effluent), the following assessment
may be inaccurate.
3.4. Water Balance – Reservoir
The initial water balance suggests that the water balance for the reservoir (i.e. the net change in
water in storage) was 10450 ML / Year, and one of the proposed industrial plants is seeking a permit
to extract 1825 ML / Year from the reservoir.
We can see that the figures above are yield a decrease in the net change in water volume in storage
in the reservoir, however there is still a significant amount of water in the reservoir throughout the

Along with the numerous natural disasters that humans face in their environment, sinkholes are
becoming a more prominent and frequent force to reckon with. Sinkholes are not a new
phenomenon, but due to human activity, these concavities are becoming increasingly common. If
humans continue to abuse underlying aquifer systems then the influx of sinkhole occurrences will
rise. Since sinkholes are naturally occurring hydrogeological systems, the only way to minimize
damage caused by this detriment is to respect and conserve water. We can counter that the Floridian

During the extremely mild winters in Florida, there is a concern that nursery crops may be lost due
to occasional freezing temperatures. To prevent this from happening, farmers will draw warm
ground water from the aquifer and spray crops to form insulating coats of ice, which ensures the
crop's safety. Due to the importance of crop protection, during longer periods of freezing weather,
farmers will pump for prolonged periods. If excess pumping is required, the surrounding area can
become overwhelmingly succumb with over–collapse sinkholes. In 2010, Craig Pittman, Tampa Bay

Persuasive Essay On Fracking
For the past six weeks, I have been doing research about fracking and it's effects on the community
and nature. I have spent hours researching and doing experiments to come to a conclusion. I would
like to share my findings with you to make sure this county is informed about the process, as I know
they might not necessarily be. I believe that Fracking should not continue in Ohio. Although it
brings jobs to the country, and bring us domestic fuel, it is becoming a health hazard to bio life,
which is very important.
Fracking (formal name hydraulic fracturing), is the process of which million of gallons of water are
pumped a mile underground to get methane out of pockets in the shale. Fracking fluid is a mixture
of chemicals and water pumped underground through supposedly safe wells. The oil companies
actually doing the fracking say that the wells are completely safe. However, only 50% of the
fracking fluid is brought out of the wells. The rest of it is left underground and never retrieved. This
can contaminate the ground we farm on an the water we drink.. Fracking affects everyone around
the wells, though it may be indirectly. It can affect someone by giving them millions of dollars for
land or contaminating their drinking water. Some environmentalists believe that this can
contaminate water in the aquifer, a mile above the shale.
The composition of fracking fluid has not been released to the public. No one knows what is in the
fluid, but people have predicted. It is thought

describe what happens at the interface by discussing the models. As well as to discuss how tides
may have an impact on seawater intrusion. Ataie–Ashtiani, Volker and Lockington(1999:17)
suggested that there is a direct relationship between the area of the dispersion, the scale, the shape,
the degree of the dispersion area, and parameters such as hydraulic conductivity, the comparative
densities of the salt and fresh water as well as the rate of discharge of the ground water. There is
limited accuracy to the usage of the models as the models are limited by assuming various
situations. Altaie–Ashtiani et al (1999:18) gestates the rare occurrence of salt–water intrusion in
ground water in two ways: the sharp–interface approach and the disperse interface approach. The
sharp–interface approach is the approach in which it should be assumed that the salt water and fresh
water are immiscible fluids which are separated by a sharp interface. This approach includes the
diffusion and the effects of the hydrodynamic

The Floridan Aquifer : The Principal Source Of Water Supply
The Floridan Aquifer extends through several southeastern U.S. states and is one of the most
productive kart landscape in the country. The Floridan aquifer system consists primarily of
limestone rocks of high permeability, and is separated into two principal hydro–stratigraphic zones
consisting of the Upper Floridan Aquifer (UFA) and the Lower Floridan Aquifer (LFA). The upper
Floridan aquifer is the principal source of water supply in most of north and central Florida: "The
Upper Floridan aquifer generally consists of the Ocala Limestone and the dolomite and dolomitic
limestones of the upper one–third of the Avon Park Formation" (OReilly, et al. 2002). The LFA

Karst System Sediment Transport System and Response
Mahler & Lynch studied the sediment transport response of springs to two storm events: one
following a wet season and the other following a dry season. They describe the temporal changes in
total suspended solids (TSS), mineralogy, and particle size distribution. Concentrations of suspended
sediment peaked 14 to 16 hours after rainfall, and the bulk of the sediment (approximately 1 metric
ton in response to each storm) discharged within 24hour after rainfall. TSS consisted of dolomite,
calcite, quartz, and clay. Sediment in karst is detrimental to aquifer permeability, wells, pumps, and
spring esthetics. Sediment can act as a vector for nutrients, contaminants, or bacterial transport.
Mahler & Lynch focused on "temporal changes in geochemical characteristics of particulates
discharging from a major karst spring in response to precipitation, and relate them to sediment
source and potential for contaminant transport" (Mahler et al. 1998). The karst aquifer investigated
was the Barton Springs segment of the Edwards aquifer in central Texas. Hourly samples for
sediment and water analyses were collected from an orifice of Main Springs following two high–
intensity storm events and one drawdown (nonstorm) event. Suspended sediment samples were

Geological Characteristics of Aquifers
Aquifers allow for individuals to be able to get ground water from wells and other water sources.
Aquifers consist of saturated rocks that allow for the passage of water through the small open spaces
between them (Lutgen & Tarbuck 2011). This is of great importance when looking and analyzing an
aquifer for its ability to be used. There are particular geological characteristics that aquifers and the
land around them must possess in order for them to be usable. Porosity of the aquifer is immensely
important as the holes in aquifers such as sandstone and fractured limestone, need to be big enough
to allow water to flow through (Lutgen & Tarbuck 2011). However, although the permeability of the
aquifer and the ground is very important, the holes that allow water to go through in order for the
aquifer to be useful cannot exceed a particular size either. If the aquifer is too permeable, too much
water will flow through too quickly, and the well that uses the aquifer will dry out; this is because
the rate at which the water is being used is faster than the rate at which the water can be replaced
(Lutgen & Tarbuck 2011). The numbers of small pores in between the aquifers are important for
filtering the water as well. The smaller the holes in the aquifers are, the more bacteria that can be
filtered therefore preventing these bacteria from reaching and endangering people. However, the size
needs to be big enough for the water to flow through so that the water does not clog and have

The Need for Groundwater Extraction Regulation
Groundwater is used primarily for irrigating farmland; and secondarily, for consumption and
industrial use. Aquifers, unconsolidated subterranean layers which hold water, are rapidly
dwindling, and groundwater depletion is quickly growing to become a major problem for farmers
and the public at large. Reserves close to ground level are rapidly drying up and due to technological
roadblocks, extracting water from deeper reserves is not yet financially feasible. The problem is
especially severe in California, which represents around 20% of all groundwater withdrawal in the
United States (Famiglietti, LA Times). A lack of water for agriculture would directly lead to
diminished food production and indirectly lead to requiring food imports from outside the state.
Groundwater resources are an unregulated public resource and despite any innovative breakthrough
in extraction techniques, the only sustainable, long–term solution is to enforce limits on extraction.
Regulation of how much groundwater can be extracted from an aquifer in a set period of time; along
with incentives to obtain water from alternative sources is the ideal solution to address the
perennially growing challenge of groundwater depletion in California.
This regulatory effort must begin in politics but it needs to spread to society as well – only when
people realize the consequences of over–extraction will they even consider ceasing doing so. This
solution is not based primarily in science and technology, and is

Florida Aquifer System
Next we will discuss the Florida Aquifer System. There are many factors that contribute to the
storage and movement of ground water, porosity and permeability are the two most important
elements to this equation (Lutgens, 2012.) Porosity is the volume of open space between rock or
sediment and permeability is the ability for a fluid to pass through (Lutgens, 2012.) Rock and
sediments that allow groundwater to travel freely are called aquifers. These aquifers are natural
resources that exist underneath the earths surface to store water. In the case of Florida's aquifer
system the system is considered to be one of the most productive in the world (USGS, n.d.) In its
entirety, the aquifer system "underlies an area of about 100,000 square miles

Analysis On The Nubian Sandstone Aquifer System
The integrated geophysical, remote sensing, isotopic and geochronologic and modelling studies on
the Nubian Sandstone Aquifer System have come up with the following findings and
recommendations:
1– Geophysical studies:
Based on the integration of gravity, magnetic, and borehole data the structural trends, uplifts and
sedimentary cover affecting the aquifer behavior have been conducted. The area of the NSAS is
affected by several structural trends in different directions; the most prominent directions are NE–
SW, N–S, E–W, and NW–SE. The dominant NE–SW trend is associated with the Pelusium and
Qattara mega shears.
The sedimentary cover shows a northward increase from less than 0.5 km in northern Sudan and
southern Egypt to more than 6 km at the Mediterranean coast. The sediments thickness shows a
shallowing of the basement rocks along the east–west trending Uweinat–Aswan basement uplift
which may impede the south to north groundwater flow and replenishment from the recharge areas
in the south.
The NE–SW trending Pelusium mega shear cuts the Precambrian rocks and continues upward in the
sedimentary cover; it formed deep structural controlled basins along its zone, which were filled by
high thick sediments of relatively high hydraulic conductivities extending from the Kufra Basin in
Libya and Chad to the northern part of Dakhla Basin in Egypt. This zone could provide a preferred
groundwater flow pathway from the Kufra to the Dakhla Basin.

Rain water harvesting and Artificial recharge of ground water
Rainwater harvesting is the technique of collection
and storage of rain water at surface or in subsurface aquifer, before it is lost as surface run off or as
evaporation.
The artificial recharge to ground water is a process by which the ground water reservoir is
augmented at a rate exceeding that under natural conditions of replenishment utilizing suitable civil

The Hazards Of The Abandoned Mining
Abandoned Mining
This hazard is important because rain, snow or wind will move materials from the abandoned place
and would contaminate aquifers through their recharge zone. It is important to first solve the use and
dispose of chemical elements exposed in a mine before abandoning it.
Ore deposits
Very often, the presence of certain elements, such as mercury, arsenic or radioactive elements, are
concentrated in an area close to the aquifers and represent a hazard. When drilling claystone is easy
to find high emissions of radiation and it is possible to read it through electrical registers inside the
well like Gamma Ray, Spontaneous Potential, and Resistivity.

It is the authorities' competency to authorize the industry activities. Villa–Pinzon, Cundinamarca, a
small town less than one hundred miles from Bogota, is located in the Bogota River Valley. A leather
industry used to use titanium to improve its manufacturing processes; after the process was finished,
the water used was poured to the Bogota River, contaminating the river's water. There are aquifers
that recharge from the Bogota River's water.
Agriculture
If the agriculture industry has advanced technological methods, that itself is a hazard for aquifers
because the water used in the process could be contaminated with chemical products such as
pesticides, insecticides or organic residues and after could go to the recharge zone for one or more
aquifers. Discriminated fumigation with glyphosate to eradicate illegal plantations contaminates
stream waters which could contaminate aquifers through recharge zones.
Over exploitation
Aquifers have a recharge area and a discharge limit, both dependent on the natural hydrogeological
and hydrological conditions. These conditions are based on the aquifers geometry, extension and
rock type among other characteristics. When the pumping amount overrides the limit and the
recharge area is not providing enough water to supply, there is a risk of overexploitation and
contamination of the aquifer.
Risk management
Due to failing projects to provide a sustainable source of drinkable water to

Aquifer In Texas
An aquifer is a permeable rock underground that bears water, this water can be collected through
wells for people to use and drink. Within Texas there are 23 different aquifers, but for Central Texas
we tend to favor Edwards Aquifer and due to this many problems have arisen for the aquifer and its
inhabitants. We will first discuss the history of Edwards Aquifer, the reasons behind the current issue
concerning the aquifer including what species are endangered and why, and lastly what solutions are
being set forth.

By plans of their cities, I mean where they might expand next or if they want to increase the
pumping of water in the area from Edwards Aquifer. What many people do not know is that the
species in Edwards Aquifer are beneficial to them from their roles in the environment. Each animal
has a role that when put together will all the other roles in the ecosystem, it creates equilibrium and
gives the aquifer the potential to survive. With these species gradually coming closer to extinction,
an imbalance is created in the ecosystem that allows for the possibility of other species to thrive that
might harm the aquifer. If the situation were to continue as it has been, then we will lose the
beneficial animals, the aquifer, and would have to deal with the problem of the new species and of
finding a new water source. In the end, no one would win, everyone would be a lost and then
pressure would possibly be put on another aquifer and then the same problem could

Maharashtra’s maximum irrigation potential
Challenges faced by many countries in their struggle for economic and social developments are
related to water (TAC, GWP 2000: 6) 2. India, too, is a varied country in terms of water availability
and Maharashtra is a peculiar State of it.
Maharashtra has uneven distribution of water resources. A large area is, therefore, water deficit
whereas a small part is bestowed with abundance of water. Maharashtra's physiography has
constraints over the creation of surface water (SW) potential for irrigation purpose. At present, the
area under irrigation is 17.5 per cent out of total cultivable area 3. One study estimates that even

In line with the policy, GSDA, following its emergence, was inclined towards executing systematic
and scientific hydrogeological surveys for exploration, assessment and development of GW sources
in the State. The organisation began with scientific approach for strategic development and
appropriate policy formulation. During this first phase GSDA carried out considerable work
pertaining to GW development. The core concept was drilling of bore wells (BW) and hand pump
installation to provide drinking water facility to rural population in view of source dependency. The
underlying objective was to provide potable and assured drinking water in every nook and corner of
the State.
State resolved the issue of drinking water scarcity by initiating BW based hand pump programs.
GSDA carried out drilling activities and drilled more than 100,000 BWs. Similarly, GSDA
recommended open dug wells (DW) to tap GW from shallow aquifer 5 that is replenishable under
normal rainfall conditions for irrigational purpose.
Consequently, the role of organisation as service provider helped tackle drinking water scarcity in
the State, placating the impatient politicians. The scientific survey by organisation helped in greater
success of DWs in terms of GW availability. However, it became imperative for organisations to
modify their structure to suit the new roles, new attitudes and approaches in its functioning. GSDA,

The Denver Basin Aquifer Framework
Denver Basin Aquifer
The Denver Basin aquifer framework is a noteworthy wellspring of water for South Metro Denver.
The system extends from Colorado Springs in the south to Greeley in the north, from the foothills
close to Golden in the west, toward the eastern fields close to Limon, is a surface locale of around
6,700 square miles. It joins four aquifers: the Dawson, Denver, Arapahoe, and Laramie–Fox Hills.
Each aquifer has different water quality, profundities, and water availability (CFWE, 2002).
Describe the source of the groundwater, that is, where is the rainfall and snowmelt that feeds the
aquifer coming from, and what are the best estimates of the travel time from the source to the point
of withdrawal.
The Denver Basin has a semi arid atmosphere in which potential yearly evaporation is around five
times greater than yearly precipitation. Most of the precipitation that falls on the land surface either
runs off in streams, is evaporated from the surface of the soil, or is consumed by vegetation.
Although this may be the case, a little part of the precipitation more often than not diffuses
downwards and recharges the groundwater system. In the Denver Basin, a lot of the recharge
happens in the highland areas between stream channels in the higher southern part of the basin.
Precipitation is more prominent here, and the porous soils derived from the Dawson Arkose allow
deep permeation. Recharge here can happen on a local and a regional scale. Locally, water moves

California Groundwater Depletion: An Ever Increasing Issue The state of California may run out of

Some people say that if California were to stop using groundwater water prices would go up, and
people do not want to pay for higher water prices. Unfortunately, water prices would go up, but this
is the price we have to pay for not regulating groundwater use for the last fifty years. Most likely,
when we would put new laws into effect, we would not totally discard groundwater, but
groundwater would be a lesser percentage of the total plan. Also, this plan would help make us more
conscientious about our groundwater use. Maybe it would cost a little more money, but is that more
important than our aquifers having water for later generations? Groundwater depletion is becoming
a growing risk, and if the Californian government does not do anything about it, it could become a
disaster.
With our water aquifers running out of water fast and our farmer pumping out water as quickly as
they can, our aquifers will not be able to replenish themselves fast enough to survive the constant
water use, and if the Californian government were to just implement a law regulating how much
water these farmers use, the state of California may be one step closer to solving the problem of
groundwater depletion. Currently, when a farmer digs a well in California, they have no limitations
on how much water they use nor do they have to tell anybody how much groundwater they use
(Pool). In California, farmers use eighty percent of the state 's groundwater, and without the

North and Central Florida Springs Essay
Introduction Groundwater is the largest and most available usable source of drinking water in the
state. There is a vast and mysterious system of caves and natural springs in North Central Florida.
The cave system within the aquifer is one of the most amazing parts. The caves are remarkable in
many ways. They are among the deepest and longest in the world, let alone the U.S. Another
amazing aspect of the system is the purity of the water. The springs collectively produce billions of
gallons of crystal clear water per day. The whole system stems from the Florida Aquifer that rests
under the entire state. When most people think of Florida, they think of the weather and the beaches,
but its the springs and the whole water ... Show more content on Helpwriting.net ...
The thousands of tourists and residents that enjoy these springs are a very good reason to protect and
cherish them. The recreation is not as important to preserve as the quality and amount of drinking
water that the springs produce. The joy that the springs give so many people and the revenue they
could generate are valid reasons to be concerned about their condition and their future. The labyrinth
of caves has been a favorite of cave divers for more than 40 years. The diving can be quite
dangerous though. Without proper precaution and safety measures divers can very well get lost or
trapped in the caves. In the last 40 years or so, about 300 divers have died in the caves.
Communities have always been based around the springs. Everyone from the Native Americans to
the settlers would have used the springs for food and water. These springs made life in Florida
possible and their importance and heritage needs to be remembered and appreciated. Small
communities like Ichetucknee are completely dependent on their spring for their way of life. The
spring and surrounding community are a cultural landmark. When the springs become endangered,
the communities and the small town way of life for North and Central Florida become endangered.
Ichetucknee Springs are endangered, just as many across the state are. Chemicals and waste from
Lake City, a town 15 miles away are showing up in trace amounts in the spring. The

The Causes Of The Drought In California
The Drought in California has lasted about five years. California is an American state known for it
agricultural industry and large cities. It is on the West Coast near the Ocean as well. It is supposed to
get both rain and snowfall throughout the year, but the drought has prevented as sufficient amount
from occurring.
The drought was caused by overuse and over extraction from water tables and freshwater sources
for the commercial agricultural industry. The biggest cause, however, was a high–pressure system
near the coast diverting storms away from California because it cannot rain California is in a
drought.
Due to this drought, many crops have dies leading to poverty for many farmers. People are lacking
clean drinking water forcing the state to bring it in from other states. Water tables are collapsing as
well.
To mitigate loss of life close monitoring of dry woods needs to occur that way if a forest fire starts it
can be put out easier, or the surrounding areas can evacuate more effectively.
People are also shifting away from grass lawns to save water from being wasted on something
purely for intrinsic value. They are also using less water for washing dishes and showering to
prevent the need for any more water extraction.
California is also importing more produce instead of growing it on their own to prevent
malnourishment and supplement the lack of produce being grown in state.
8. Hurricane/serious storm case study: discuss a serious hurricane or tropical storm. Where did it hit
and what impact did it have? How did/could weather monitoring mitigate loss?
Hurricane Katrina hit The United States and Canada. In the United States, it did the most damage in
New Orleans, Louisiana. It also hit parts of Florida, Georgia, Pennsylvania, Ohio, Mississippi and
Alabama.
It came onto land as a Category three hurricane with powerful windspeeds reaching more than 125
miles per hour.
New Orleans is a large city hit by Katrina with most the land being lower to sea level making It
prone to flooding. It is also has the Mississippi river flowing through it. There are many poverty–
stricken neighborhoods usually in areas with more flooding.
Meteorologists were capable of predicting Hurricane Katrina

Florida's Water Issues: Saltwater Intrusion
Florida's Water Issues – Saltwater Intrusion Saltwater intrusion leading to contaminated drinking
water wells has long been feared in South Florida. Saltwater intrusion occurs naturally to some
degree in most coastal aquifers, owing to the hydraulic connection between groundwater and
seawater. Because saltwater has a higher mineral content than freshwater, it is denser and has a
higher water pressure. There are three primary mechanisms by which saltwater contaminates the
freshwater reservoir in the unconfined, surficial aquifers of the region: one, subsurface movement of
seawater (lateral large–scale intrusion), two, seepage of seawater from tidal canals and streams, and

The Conservation And Recycling Of Water
Currently California has a terrible water problem, which is causing many people to cease watering
in excess all across the state. The reason California has water problems is that we are emptying our
underground aquifers during a drought that has been going on and many people are still wasting
water on their own personal opportunities. There are many options toward either ending or surviving
the water issue, such as the idea of war to take the water that California needs to survive. Another is
to build a pipeline from a place with extra rainfall annually that California can syphon off for usage.
Another is the option to conserve water across the state and to reuse water as much as possible to
minimize excess water usage. The most viable of these solutions is the conservation and recycling of
water. By conserving and recycling water there is no waste, only recycled water for cleaning dishes,
watering plants, and washing houses and cars. The only foreseeable problem is that the process
cannot be monitored and people are only held by honesty and a promise to do what they can to
conserve water, but the conservation of water seems to be the most affordable, quickly enacted, and
can be done by most families. Also the other options require a higher amount of financial support to
begin and continued maintenance, large spans of time to orchestrate, and would need a lot of
manpower. With the option of water conservation time, money, and manpower is not as high of a
needed factor when
