It would take more than one thousand years to restore all the U.S. bodies of water currently polluted by agricultural runoff and other forms of indirect water contamination, a government report found.
The year-and-a-half long investigation by the Government Accountability Office concluded that “progress toward the Clean Water Act’s goals of restoring and maintaining” the “biological integrity” of the nation’s waters has stalled because nonpoint-source pollution, or pollution from diffuse sources such as runoff and seepage, has not been controlled.
The Government Accountability Office serves as a federal watchdog and investigates issues on Congress’s request.
It released its report, “Changes Needed If Key EPA Program Is to Help Fulfill the Nation’s Water Quality Goals,” late last year, shortly before the passage of the new Farm Bill that offers millions in conservation incentives to farmers.
“Increased corn acres and more intensive row crop production causes more erosion and more use of fertilizers that then give rise to additional flush out of nutrients in storm water,” said John Braden, a former agriculture-department professor at the University of Illinois at Urbana-Champaign who specialized in environmental and natural-resource economics. “But the farmers do not benefit from cleaning up those problems, nor do they pay the cost of creating the problems in the first place.”
The National Water Quality Inventory also informs Congress and the public about widespread water quality problems.
The inventory has regularly placed agricultural nonpoint-source pollution as the leading cause of water problems for rivers and lakes and the second leading cause of problems for wetlands.
It has also routinely listed agricultural nonpoint-source pollution as a top contaminator of estuaries and ground water.
Even so, the Clean Water Act of 1972 mostly regulates industrial sources of pollution and neglects agricultural runoff. The oversight has some environmental advocates saying changes need to be made to avoid further contamination of U.S. waters.
“The Clean Water Act does not directly regulate the vast majority of pollution discharges from crop production, because it exempts from pollution permitting both agricultural storm water and flow back from field irrigation, and because a bunch of different agricultural activities do not typically need permits even when they discharge dirt or other solids into protected waters,” said John Devine, a senior attorney for the Natural Resources Defense Council’s water program.
Braden said that any regulation changes are doubtful.
“Gridlock seems to be the rule of the day, and certainly there are strong forces that are not sympathetic to increased regulation,” Braden said.

Grazing, plowing, pesticide spraying, irrigation, fertilizing, planting and harvesting are just some of the common agricultural activities that result in notable amounts of polluted runoff.
Ever-growing concentrated animal feeding operations, which house thousands of livestock animals in confined spaces, have also been added to that list within the last couple decades.
Contaminants that result from those activities include sediments, nutrients, pathogens, pesticides and salts, all of which can hinder the wellbeing of water ecosystems.
Nitrogen is a “persistent” and “durable” plant nutrient found in fertilizers that help make crops grow, Braden said, adding that it is also found in animal waste.
Numerous negative consequences arise when large amount of nitrogen are carried into water ecosystems by either rain or irrigation.
Increased algae growth is one repercussion, Braden said. Unbalanced algae growth can lead to decreased oxygen levels in a water body, killing plants and animals in the process.
Too much nitrogen in water bodies used for human drinking water can also be dangerous, according to the U.S. Geological Survey.
Excessive nitrogen restricts oxygen movement throughout the bloodstream.
When infants younger than five months are exposed to water with high nitrogen levels, they may develop the circulation problem known as “blue baby syndrome.” Infants with blue baby syndrome develop a blue-tinted skin color and become lethargic.
The syndrome can lead to coma and death when not treated.
In places throughout Eastern Europe where groundwater has been contaminated by high nitrogen levels, authorities distribute water bottles to women and young children to avoid such medical hazards.
Braden said these primary consequences may have additional effects, as well. Safety officials could ban water activities, such as swimming and boating. If too many plants and animals die because of over-algae growth, fishing industries could suffer.
“Some places like the Gulf of Mexico and the Chesapeake Bay have been smacked really hard by increased fertilizer use and manure generation,” Braden said.
Contaminates from agricultural runoff have also been shown to change the hormonal neutrality of a water body. A Wisconsin Center for Investigative Journalism investigation revealed that manure was a possible source for endocrine-disrupting chemicals found in half of 40 wells in northeastern Wisconsin.
“You get changes in the whole ecosystem as a result of these nutrient imbalances,” Braden said.
Marketplace demands overshadow conservation efforts
Some critics are quick to use these and other examples as evidence to label the agricultural industry as irresponsible.
However, Braden said criticism is unfair because farmers and agricultural producers are caught in the middle of a supply and demand dilemma.
“The markets are encouraging farmers to produce, produce, produce, and at the same time there are certain elements of the public that want their water clean, clean, clean,” Braden said. “And those demands for clean water are not expressed through the marketplace.”
Earlier this month, the U.S. Department of Agriculture announced that farmers will plant more soybeans in 2014 than ever before.
It also announced that the United States will export more meat to China than ever before.
Sophia Kruszewski, a policy specialist with the National Sustainable Agriculture Coalition, said that societal trends may be reversing that demand dilemma, though.
The National Sustainable Agriculture Coalition is a group of farming organizations dedicated to advancing the sustainability of agriculture, food systems, natural resources and rural communities. Farms and agricultural producers from throughout the country are among its many members.
“I would agree that increasing global food demand is placing a strain on available natural resources and exacerbating problems associated with agricultural runoff and pollution,” said Kruszewski. “But, there is also a growing demand for foods that are produced in environmentally responsible ways.”
Kruszewski said that the new Farm Bill enacted in February presents opportunities to better manage agricultural runoff and nonpoint-source pollution from a policy perspective.
Under the new bill’s regional conservation partnership program, farmers and ranchers are encouraged to work with the Natural Resources Conservation Service to make their farms more sustainable.
If a farmer or rancher partners with the conservation service, the agency will help install and maintain sustainable agriculture methods with the hope of preventing additional soil erosion or water contamination.
Congressional Budget Office projections show that U.S. conservation programs will receive more than $57 billion dollars throughout the next decade.
Braden, who last year wrote an essay on innovative ways to address nonpoint-source pollution, said that incentivizing farmers for employing more sustainable methods through tax credits could also be effective.
“More than ever before, the consumer wants to know who is producing their food and under what conditions,” said Kruszewski. “And we need policies and programs that support producers willing to meet that demand – that help protect and rebuild soil and conserve and improve water quality, all while maintaining productive farms and ranches.”
More on water pollution: a summary of America’s waters
The December Government Accountability Office report analyzed nonpoint-source pollution by examining state and national pollution goals, which are known as “total maximum daily load” targets.
The Environmental Protection Agency and individual states each are responsible for developing and implementing total maximum daily load pollution targets for specific bodies of water that are negatively impaired by chemical, physical and biological stressors.
EPA officials then oversee statewide efforts to ensure that those targets are being met.
Between 1996 and August of last year, more than 50,000 targets were identified and established in the United States, according to the accountability office report.
A review of those targets shows that nearly one out of every four targets involves pathogens, such as bacteria from animal feces.
About one out of every five targets involves either nutrients or sediments.
“[Sediments] makes the water muddy and it causes sediment buildup on the bottom that then has the effect of reducing habitat,” John Braden, a former agriculture-department professor at the University of Illinois at Urbana-Champaign, said.
More than half of the targets are for bodies of water that have been negatively affected by nonpoint-source pollution. Another 41 percent are for bodies of water that have been negatively affected by both point-source pollution and nonpoint-source pollution.
Unlike nonpoint-source pollution and runoff, point-source pollution comes from a single point, such as a waste pipe.
Just 5 percent of targets address point source pollution.
The EPA has assessed 18 million acres of lakes and more than 940,000 miles of rivers, according to the accountability office report.
The majority of those assessed water bodies do not meet designated-use standards for simple activities such as fishing, swimming or drinking.
More than one out of every two miles of EPA-assessed rivers and more than two out of every three acres of EPA-assessed lakes are labeled as “environmentally impaired.”

If Conservatives continue to run our Congress, if they win the Senate and the State’s once again claim REDNESS within their borders……Who is going to care anymore about water, resources or environment? Americans need to get off their “FENCE SITTING PERCHES” and they need to start finding a voice, not one that speaks for them, but one that speaks for the future of their children and the planet. NAW, IT’S TOO MUCH TO ASK OF AMERICANS……the basic fundamental idea of thinking has been erased from most of America’s minds, it’s an ability that will soon be extinct in humans.
“If Conservatives continue to run our Congress…” They don’t. King Harry Reid of the (D) brand runs the Senate.
You are pretty ignorant aren’t you! time to sit down and shut up.
So what is it about non-conservative Harry Reid running half of Congress that causes you heartburn?
