Hussainsagar - The lake that was
The lake that was
For the non-adventurous , the lake was approachable from the Secunderabad Sailing Club or the Hyderabad Boat Club on the opposite end. A bus ride on the top deck of a doubledecker bus through Tankbund was enticing . Racing records were broken and set on Tankbund road.
Through the eighties and nineties, dramatic changes swept the lake's environs . Tankbund road got broadened, beautified and statuefied ! The Buddha Purnima Project got underway, the Necklace road came up, and the monolith Buddha was transported prostrate on a huge vehicle with over a hundred wheels, only to fall in the lake on its way to the rock of Gibralter , killing several people.
But there were other ugly things happening along with the beautifi cation . Patancheru industrial estate's effluents and the city's sewage began to get free access to the lake. The clear water of the lake went so turbid that Buddha's rescue was a nightmare. Stench around the lake became insufferable. Governor Kumudben Joshi as also Governor Kishan Kant would lament in personal conversation about how the stench obliterated the joy of an enticing view from their residence. Then came a time when eating the lake's fi sh could endanger one's health.
Although Husainsagar's beautifi cation has enraptured everyone, the lake has been dying a slow death. Moreover , the banks of Husainsagar has become the best destination for the lastjourney of our politicians. And who knows, the fate of Masab tank might befall Husainsagar in a few decades, and then the transition from a park to a mall will be only a matter of real estatestrategy!
This water quality assessment was conducted by NEERI on the request of the Hyderabad Metropolitan Water Supply & Sewerage Board. The study revealed a very low, and in some locations zero, presence of dissolved oxygen (DO) in the Hussainsagar thereby indicating the fragile lake water quality and the effect of organic pollution. The study concluded that the lake was in an advanced stage of 'Eutrophication' , which means that there was an increased plant growth in the water body. According to experts this accelerated growth is either due to natural fertilizing agents washed from the soil or dumping of chemical fertilizers. Eutrophication may also occur due to drainage of sewage, industrial wastes or detergents into a body of water.

Water Pollution due to farming - Ohio
Water quality issues
Nutrient and sediment loading into Ohio’s lakes and streams has been an issue for 40 or more years, and farmers’ conservation efforts have made a substantial improvement.
But, in the past year or two, it’s become increasingly clear more efforts are needed to tackle a slightly different issue: dissolved reactive phosphorous. Unlike other forms of phosphorous, the dissolved form is considered 100 percent available to unwanted plant growth — namely the harmful algal blooms.
Throughout the first part of the year, state officials put together a statewide task force to address what farmers should do. The group became known as the Agricultural Nutrients and Water Quality Work Group, and is comprised of staff from Ohio Department of Agriculture, the department of natural resources and Ohio Environmental Protection Agency.
Dozens of farmers and farm agencies are helping the group form new recommendations for Ohio, to help improve water quality and reduce dissolved phosphorous levels.
By the close of the year, water quality was on the minds of grain and livestock farmers across the state.

Charles 'Mac' Mathias, founder of Chesapeake Bay cleanup effort, dies
Charles 'Mac' Mathias, founder of Bay cleanup effort, dies
By Karl Blankenship
Charles McC. Mathias Jr., a three-term United States senator from Maryland who was instrumental in launching the Chesapeake Bay restoration effort, died Jan. 25 at his home in Chevy Chase, MD, of complications from Parkinson's Disease. He was 87.
Mathias, who served in the U.S. House from 1961 through 1969, then in the Senate until 1987, was a liberal Republican who sponsored civil rights legislation, advocated for equal rights for women and was critical of the Vietnam War. He was called "the conscience of the Senate" by its Democratic leader, Mike Mansfield.
Mathias also played a pivotal role in Chesapeake restoration, even though he grew up far from the Bay in western Maryland. Sen. Barbara Mikulski, who was elected to Mathias' seat after his retirement, hailed him as "the founding father of a great and ongoing effort to save the Chesapeake."
As a first-term senator, Mathias heard a growing number of complaints from Marylanders about the Bay's condition and its poor water quality. "I remember when I was a small child, the Chesapeake Bay was pretty clear," he recalled in 2003 interview with the Bay Journal. "Now it looked just muddy."
In 1973, "Mac" as he was commonly known, took a a five-day, 450-mile tour of the Chesapeake Bay for a firsthand look at problems facing the Bay.
Then-EPA Administrator Russell Train was along for part of the trip, as was Interior Secretary Rogers Morton. Along the way, Mathias talked to more than 150 people, from businessmen to government officials to watermen to farmers to scientists. "Everyone we met was interested and wanted to be a part of it," he said. "The spirit of the time was tremendous."
The boat trip, Mathias said, gave him a sense of the diverse problems facing the Bay, from discharge pipes leading out of cities, to runoff from rural areas, to the loss of underwater grass beds almost everywhere. "By pulling all of these things together, you got a comprehensive picture of what all the problems of the Bay were," he said. "They were not just one thing."
After the trip, Mathias pushed for increased attention on the Bay, which ultimately resulted in a five-year, $25 million study by the EPA. The state-federal Chesapeake Bay Program was created in 1983 in response to the findings of that study.
Two decades after the Bay Program was started, though, he said he was not surprised the task of restoring the Chesapeake was still under way. "I had hoped it could be completed long before this, but in a way there is no completion," he said. "It is an ongoing problem because of the difficulties that feed the problem."
"The fact there are thousands of homes being built ultimately ends in a greater burden on the Bay from all kinds of pollution," he said. "We are beginning to realize that it has to be an ongoing project. As long as there are human activities in the Bay there are going to have to be offsetting programs to deal with them."
Nonetheless, he said, "I think we've come a long way." And, he said, other politicians should follow his lead by taking a trip like his to appreciate the diversity of issues afflicting the nation's largest estuary. "I would recommend it."

INTERIM REPORT OF THE INTERAGENCY OCEAN POLICY TASK FORCE
INTERIM REPORT OF THE INTERAGENCY OCEAN POLICY TASK FORCE
...
Half of the oxygen we breathe comes from microscopic plants living in the ocean.
...
Human and marine ecosystem health are threatened by a range of challenges, including increased levels of exposure to toxins from harmful algal blooms and other sources, and greater contact with infectious agents. Areas in numerous bays, estuaries, gulfs, and the Great Lakes are now consistently low in or lacking oxygen, creating dead zones along our bays and coasts.
......
Obstacles and Opportunities
Nonpoint source pollution (pollution that comes from diffuse sources instead of one specific point), caused by poor land management practices, is the leading cause of water quality problems in the United States and a major cause of rapidly declining ocean and coastal ecosystem health. Runoff from suburban streets and lawns, agricultural and industrial uses, transportation activities, and urban development – even hundreds of miles away – negatively impacts water quality, resulting in deleterious effects on ocean, coastal, and Great Lakes systems as evidenced by harmful algal blooms, expansive dead zones, and increased incidents of human illness. Areas with particularly poor water quality are known to experience frequent beach closures, massive fish kills, and areas of toxic sediments. Since this pollution comes from many diffuse sources throughout the country, addressing it requires a strong commitment to coordination and cooperation between multiple sectors and among Federal, State, tribal, local authorities, and regional governance structures. Fortunately, a number of point and non-point source prevention programs are available to State, tribal, local, regional, and private entities to reduce the amount of pollutants that are transported from our Nation’s watersheds and into our coastal waters There are opportunities to achieve significant reductions in these inputs to our coasts and ocean through concrete mechanisms that integrate and coordinate land-based pollution reduction programs.

Clean Water Laws Are Neglected, at a Cost in Suffering

Jennifer Hall-Massey knows not to drink the tap water in her home near Charleston, W.Va.
Clean Water Act Violations: The Enforcement Record
The New York Times surveyed violations of the Clean Water Act in every state, and the response by state regulators.
How Safe Is Your Water? (September 13, 2009)
Damon Winter/The New York Times
Jennifer Hall-Massey relies on drinking water that is brought in by truck and stored in barrels on her porch near Charleston, W.Va.
In fact, her entire family tries to avoid any contact with the water. Her youngest son has scabs on his arms, legs and chest where the bathwater — polluted with lead, nickel and other heavy metals — caused painful rashes. Many of his brother’s teeth were capped to replace enamel that was eaten away.
Neighbors apply special lotions after showering because their skin burns. Tests show that their tap water contains arsenic, barium, lead, manganese and other chemicals at concentrations federal regulators say could contribute to cancer and damage the kidneys and nervous system.
“How can we get digital cable and Internet in our homes, but not clean water?” said Mrs. Hall-Massey, a senior accountant at one of the state’s largest banks.
She and her husband, Charles, do not live in some remote corner of Appalachia. Charleston, the state capital, is less than 17 miles from her home.
“How is this still happening today?” she asked.
When Mrs. Hall-Massey and 264 neighbors sued nine nearby coal companies, accusing them of putting dangerous waste into local water supplies, their lawyer did not have to look far for evidence. As required by state law, some of the companies had disclosed in reports to regulators that they were pumping into the ground illegal concentrations of chemicals — the same pollutants that flowed from residents’ taps.
But state regulators never fined or punished those companies for breaking those pollution laws.
This pattern is not limited to West Virginia. Almost four decades ago, Congress passed the Clean Water Act to force polluters to disclose the toxins they dump into waterways and to give regulators the power to fine or jail offenders. States have passed pollution statutes of their own. But in recent years, violations of the Clean Water Act have risen steadily across the nation, an extensive review of water pollution records by The New York Times found.
In the last five years alone, chemical factories, manufacturing plants and other workplaces have violated water pollution laws more than half a million times. The violations range from failing to report emissions to dumping toxins at concentrations regulators say might contribute to cancer, birth defects and other illnesses.
However, the vast majority of those polluters have escaped punishment. State officials have repeatedly ignored obvious illegal dumping, and the Environmental Protection Agency, which can prosecute polluters when states fail to act, has often declined to intervene.
Because it is difficult to determine what causes diseases like cancer, it is impossible to know how many illnesses are the result of water pollution, or contaminants’ role in the health problems of specific individuals.
But concerns over these toxins are great enough that Congress and the E.P.A. regulate more than 100 pollutants through the Clean Water Act and strictly limit 91 chemicals or contaminants in tap water through the Safe Drinking Water Act.
Regulators themselves acknowledge lapses. The new E.P.A. administrator, Lisa P. Jackson, said in an interview that despite many successes since the Clean Water Act was passed in 1972, today the nation’s water does not meet public health goals, and enforcement of water pollution laws is unacceptably low. She added that strengthening water protections is among her top priorities. State regulators say they are doing their best with insufficient resources.
The Times obtained hundreds of thousands of water pollution records through Freedom of Information Act requests to every state and the E.P.A., and compiled a national database of water pollution violations that is more comprehensive than those maintained by states or the E.P.A. (For an interactive version, which can show violations in any community, visit www.nytimes.com/toxicwaters.)
In addition, The Times interviewed more than 250 state and federal regulators, water-system managers, environmental advocates and scientists.
That research shows that an estimated one in 10 Americans have been exposed to drinking water that contains dangerous chemicals or fails to meet a federal health benchmark in other ways.
Those exposures include carcinogens in the tap water of major American cities and unsafe chemicals in drinking-water wells. Wells, which are not typically regulated by the Safe Drinking Water Act, are more likely to contain contaminants than municipal water systems.
Because most of today’s water pollution has no scent or taste, many people who consume dangerous chemicals do not realize it, even after they become sick, researchers say.

Bangladesh, Dhaka: dying rivers threaten residents
Bangladesh, Dhaka: dying rivers threaten residents
Posted: 20 Jul 2009 01:30 AM PDT
Severe pollution is rendering the rivers around the capital, Dhaka, biologically dead, with specialists warning the situation is beyond rescuing. “The rivers around Dhaka have too little oxygen for the survival of aquatic life,” Umme Kulsum Navera, assistant professor of Water Resource Engineering (WRE) of Bangladesh University of Engineering and Technology, told IRIN. “The water is especially toxic during the dry seasons,” he said. While oxygen levels increase during the monsoons, they are still too low for a healthy, thriving aquatic environment.
According to research conducted by the WRE, some invertebrates and small organisms come to life in these rivers when water-flow increases at this time. But in the dry season, these life forms completely disappear in
In past decades, the changing nature of the river has forced many – particularly fishermen – to switch livelihoods as the Buriganga – one of the four major rivers that encircle the city (the others are Shitalakhya, Turag and Balu) – no longer holds any fish.
[...] Even the slightest physical contact with the water, which could be described as nothing more than raw sewage, is potentially hazardous, say health experts. “Most of the boatmen around the Buriganga have several types of skin disease. The poisonous water is responsible as there are major toxic elements in the water, from irritants to carcinogens,” Abdal Miah, a dermatologist in Dhaka.
Meanwhile, the Shitalakhya, another major river that flows along the eastern part of the city, has become so polluted that its foul stench can be smelled half a kilometre away.
Industrial dumping is primarily responsible for the Buriganga’s state. According to the UN Environment Programme (UNEP), the tanneries around the Buriganga are the leading culprits.
Despite a 1995 Environment Conservation Act, stipulating that all industrial units must have proper treatment plants to get clearance from the Department of Environment (DoE) and hence supplies of gas and electricity, the reality is quite different.
According to the Institute for Environment and Development Studies (IEDS), a leading local environmental NGO, thousands of small and medium factories dump industrial effluent directly into the rivers.
Some 40,000MT of toxic sludge containing hydrogen sulphide, ammonia, chlorine, chromium and other harmful chemicals from the tanneries are discharged into the Buriganga every day.
“The concentration of organic pollutant in the Buriganga is 17 times higher than the allowable limit of 3mg per litre. Chemical pollutants like ammonia, aluminium, cadmium, lead and mercury have also been detected in the Buriganga,” SM Mahbubur Rahman, head of the water resource planning division of the Institute of Water Modelling (IWM), said.
The lone sewage treatment facility operated and maintained by Dhaka Water Supply and Sanitation Authority (DWASA) has a treatment capacity of 0.12 million cubic metres per day, while the daily volume of sewage generated in Dhaka city is 1.3 million cubic metres.
The untreated portion is dumped into the rivers around Dhaka.
At a conference on drinking water in Dhaka held in May 2009, the Industries Minister Dilip Barua admitted that the industrial sector lacked social responsibility plans, especially when it came to effluent treatment plants. The installation of such plants would be enforced stringently by the government and efforts would be taken to relocate the tanneries from the capital city, he said.

Ganga, Yamuna "no cleaner" now than 20 yrs ago, says Ramesh
Ganga, Yamuna "no cleaner" now than 20 yrs ago, says Ramesh
PTI 17 July 2009, 03:58pm IST
NEW DELHI: In a frank admission, Government on Friday said in Lok Sabha that rivers Ganga and Yamuna were "no cleaner" now as they were two decades ago despite spending over Rs 1,700 crore.
"I admit with full responsibility that Ganga and Yamuna are no cleaner than 20 years ago," said environment minister Jairam Ramesh while responding to a Calling Attention Motion on checking pollution in rivers and lakes in India.
He said a "determined and renewed effort" was required to cleanse these major rivers.
To a question by BJP member Adityanath on the cleanliness of the two major rivers of North India, Ramesh said he could provide figures on their pollution levels but "I myself don't believe these numbers. ... For a layman, the answer is a depressing 'no'".
While over Rs 816 crore was spent on two phases of the Ganga Action Plan (GAP), Rs 682 crore was spent on the first phase of the Yamuna Action Plan (YAP) in the first phase and another Rs 190 crore on the second phase so far, he said.
Referring to the National Ganga River Basin Authority headed by Prime Minister Manmohan Singh, he said global tender for project consultants to prepare a basin management plan have attracted 30 bids and the selection would be done in the next two months.

Its quite clear that the problem is not funds or implementation.
The technology being used is not adequate to solve the problem.
A new approach has to be adopted to solve the problem.

Maryland Coastal Bays Program

Coastal bays decline troubling
Worcester County receives wake-up call on water quality
June 14, 2009
Worcester County's coastal bays are beginning to suffer a decline in water quality, according to a report recently released by the Maryland Coastal Bays Program and other agencies. Even the southern Chincoteague Bay, normally one of the cleaner areas, is seeing a drop. The coastal bays overall received a grade of C+, while the Chincoteague Bay got a B-. The healthiest was the Sinepuxent Bay, which borders the federally protected Assateague Island National Seashore, while the Newport Bay and St. Martin River, both of which receive runoff from nearby developed areas, earned grades of D+.
Advertisement
The measurements that dictated these report card-style grades include quantity of seagrasses and hard clams on the bay floor, nitrogen and phosphorus levels in the water itself, chlorophyll counts and dissolved oxygen in the water.
There is concern that the coastal bays could fall into the kind of decline seen in the Chesapeake Bay, and rightly so.
Tracking the health of these various bodies of water in Worcester County appears to provide some insight into the impact human activities can have on waterways. The healthiest water is found adjacent to waters whose shores see little human activity, thanks to protection provided by the area's national park status. The worst water quality exists in areas that receive high levels of nutrient runoff. The unexplained wild card is the decline in Chincoteague Bay, an area that sees little growth.
While these particular bodies of water are of greatest relevance to Worcester County residents and visitors, what is happening there can provide valuable information that could be used to protect and/or help restore water quality to other areas in the region.
It is important to remember, however, that what happens throughout the watershed can affect all of the waterways within it.
Given northern Worcester County's reliance on tourism, which is in turn based on a pristine natural environment that offers opportunity for recreational boating, fishing and other water-based activities as well as the presence of beaches and ocean, stemming this decline in water quality before it begins to impact these activities is important on many levels.
If the tide can be turned in the coastal bays, perhaps the knowledge gained could then be applied to the larger Chesapeake Bay to help begin a widespread return to healthier waters and habitat in that unique treasure.

Diatoms in Long Island Sound
The Soundkeeper of Long Island Sound has written one such article on the research done by Dr Ellen Thomas of Yale University.
The Soundkeeper Mr Backer is also a State Representative of Connecticut.

Attack of the Jellifish--Is nitrogen pollution changing the food chain in the Long Island Sound?
By: Terry Backer and Julia Hyman
Ellen Thomas, PhD, a professor at Yale and Wesleyan University, released findings showing that nitrogen pollution, and perhaps warming waters, may have changed the basis of the food chain in the Long Island Sound. Her research shows that a key shift in populations of microscopic algae has been occurring over the last several decades. This fundamental shift in the Sound’s menu of who eats what is likely to cause many familiar species’ populations to decrease.
At the base of the Sound’s food chain are diatoms--single celled organisms that are found in fresh and salt water. Foraminifera, or forams, are also single celled organisms which adopt dazzling and intricate shapes with many looking like exotic microscopic seashells. Until recently the most common foram in the Sound was Elphidium excavatum, which eats diatoms. For 10,000 years diatoms were the most important microscopic algae suited to the Sound’s water temperatures and nutrient levels (including nitrogen). The marine biota that we know thrived, either directly or indirectly, on these organisms.
Historically, and up until the 1990s, E. excavatum was the dominate species of foram in the Sound. E. excavatum as well as copepods (small crustaceans eaten by many fish), rely on a diet of diatoms to maintain their population. Diatoms need not only nitrogen to grow (like other plants), but also need silica which they use to form a thin exoskeleton, just like grass contains some silica. Humans add a lot of nitrogen to the Sound from polluted runoff and sewage treatment plants, but no silica, so that ratio (N/Si) becomes unfit for diatoms to thrive so that now, other microscopic algae are out-competing diatoms. This is happening in parts of the Sound right now, especially in western Long Island Sound.
Excessive nitrogen from sewage treatment plants, polluted runoff from storm water and other sources has pushed the nitrogen-silica ratio out of whack, and thus lowered the population of diatoms available for E. excavatum. Other micro-organisms, like cyanobacteria, commonly known as blue-green algae, do not need silica to survive, and in fact many species of cyanobacteria thrive in high nitrogen environments, but these organisms are not suitable as food for many animals at the bottom of the food chain. Cyanobacteria are not a good food source for most organisms, the reason being that they’re just too small to eat.
As diatom availability drops so do populations of its consumers, eventually leaving a gap to be filled. This is where another species of foram steps up:Ammonia beccarii, which has a much wider food range. It eats diatoms andother algae. This wider diet gives A. beccarii a great advantage on E. excavatum. A. beccarii has always existed in the Sound, but in lower numbers compared to E, however, it is now becoming the dominant species in western Long Island Sound.
WHO CARES?
We do. The decreasing population of E. excavatum signifies a fundamental shift in the Sound’s food chain. Our good old, traditional E. excavatum is slipping to second place in favor of A. beccarii, the species more tolerant of excessive nitrogen levels. Small diatom-feeding organisms form the base of a food chain that begins with diatoms and ends with animals we like to eat like lobster, scallops, and many fish.
Attack of the Killer Jellyfish?
Here’s the rub: Jellyfish are one of the few organisms that have no problem eating blue green algae. Jellies can feed on smaller particles in the water. This shift in the food chain could mean jellyfish become dominant over the seafood we crave. Couple this with pH changes and warming waters and we have the stuff of a B-grade movie. Jellyfish don’t appear on many menus here…yet. They can be poisonous and, as many know, uncomfortable to swim with, to say the least. Also, jellies feed on the larval stage of many of the animals we eat, which further causes their population to drop.
These tiny forams are sending a message to us about our pollution in the Sound. Are we listening?

Chesapeake 2000 - Targets
Nutrients and Sediments
Continue efforts to achieve and maintain the 40 percent nutrient reduction goal agreed to in 1987, as well as the goals being adopted for the tributaries south of the Potomac River.
By 2010, correct the nutrient- and sediment-related problems in the Chesapeake Bay and its tidal tributaries sufficiently to remove the Bay and the tidal portions of its tributaries from the list of impaired waters under the Clean Water Act. In order to achieve this:
1. By 2001, define the water quality conditions necessary to protect aquatic living resources and then assign load reductions for nitrogen and phosphorus to each major tributary;
2. Using a process parallel to that established for nutrients, determine the sediment load reductions necessary to achieve the water quality conditions that protect aquatic living resources, and assign load reductions for sediment to each major tributary by 2001;
3. By 2002, complete a public process to develop and begin implementation of revised Tributary Strategies to achieve and maintain the assigned loading goals;
4. By 2003, the jurisdictions with tidal waters will use their best efforts to adopt new or revised water quality standards consistent with the defined water quality conditions. Once adopted by the jurisdictions, the Environmental Protection Agency will work expeditiously to review the new or revised standards, which will then be used as the basis for removing the Bay and its tidal rivers from the list of impaired waters; and
5. By 2003, work with the Susquehanna River Basin Commission and others to adopt and begin implementing strategies that prevent the loss of the sediment retention capabilities of the lower Susquehanna River dams.
------------------
It appears that these goals have not been met.

Obama's Environment policy
Obama : Water issues seen as likely priorities
Greenwire -- US EPA’s efforts to improve water-treatment infrastructure, regulate emerging contaminants and protect wetlands are likely to grow in an Obama administration that has vowed to make climate change a top priority.EPA’s outgoing water administrator, Benjamin Grumbles, predicted that mitigating climate change’s impact on water supplies will be a priority for the Obama administration. “Water is at the heart of the climate change debate,” Grumbles said in an interview. “It is a core part of both the cause and the effects of climate change.”President-elect Barack Obama promised during the campaign to increase federal funding for water-treatment facilities and support initiatives aimed at reducing stormwater runoff. And prospects for a greater federal investment in water infrastructure have risen with concerns about the nation’s flagging economy. Democrats have called for using water projects and other infrastructure work as an economic stimulus.The Bush White House recently threatened to veto House plans for an economic recovery package funding infrastructure projects, potentially punting the issue to Obama and the 111th Congress. Obama said last week that passage of a $60 billion to $100 billion economic stimulus package would be a top priority following his inauguration if President Bush and lawmakers do not come to an agreement in the lame-duck session (E&ENews PM, Nov. 7).Federal funding for infrastructure has declined 70 percent over the last two decades, leaving much of the nation’s water and transportation infrastructure in desperate need of cash for maintenance, water-industry representatives say.“We hope that the package will contain upwards of $10 billion for wastewater infrastructure,” said Susan Bruninga, spokeswoman for the National Association of Clean Water Agencies. “These are critical needs our communities have waiting. We’re ready to stick the shovels in the ground. These are projects that are necessary for environmental protection and public health.”
Cost of Nitrogen and Phosphorous pollution

Phosphorous Pollution Costs US $4.3B Annually
MANHATTAN, KS -- Pollution by phosphorous and nitrogen isn't just bad for lakes, streams and other bodies of fresh water. According to researchers at Kansas State University, it's also bad for Americans' pocketbooks.Freshwater pollution impacts individuals on a level as basic as how much they spend on bottled water, said Walter Dodds, professor of biology at K-State. If you worry about what's in the tap water, you might be shelling out more money for the bottled variety, he said.If your municipal water plant has to spend more money to treat the water coming through your tap, your water bills will increase. If you own a house on a lake that is becoming increasingly polluted, your property values likely may drop. If that lake is a recreation destination, your local economy could take a hit, too."Monetary damages put environmental problems in terms that make policymakers and the public take notice," Dodds said.He and the K-State researchers looked at U.S. Environmental Protection Agency data on nitrogen and phosphorous levels in bodies of water throughout the country. Nitrogen and phosphorous are nutrients that are applied to plants as nutrients.Dodds said that the majority of this type of pollution is from nonpoint sources --that is it's not flowing into a lake or stream like sewage outflow coming from one pipe. Rather, the nitrogen and phosphorous are reaching the water from various points, such as, for example, runoff from row crop agriculture across the surrounding countryside.The researchers calculated the money lost from that pollution by looking at factors like decreasing lakefront property values, the cost of treating drinking water and the revenue lost when fewer people take part in recreational activities like fishing or boating.The researchers found that freshwater pollution by phosphorous and nitrogen costs government agencies, drinking water facilities and individual Americans at least $4.3 billion annually. Of that, they calculated that $44 million a year is spent just protecting aquatic species from nutrient pollution."We are providing underestimates," Dodds said. "Although our accounting of the degree of nutrient pollution in the nation is fairly accurate, the true costs of pollution are probably much greater than $4.3 billion."Dodds said he anticipates the research being used by policymakers because it documents the extent of the nutrient pollution problem in the United States and one facet of why it matters."Putting environmental problems in terms of dollars allows people to account for the actual costs of pollution," Dodds said.Web site: http://www.k-state.edu/
