Lists Water Pollution Resources (UK Rivers Network) Provides over 100 sources of information to help reduce various forms of water pollution, such as from fertilizer, oil spills and slicks, algae blooms, decommissioning of oil platforms and structures, debris and dumping of wastes, sewage and wastewater, atmospheric deposition (ocean pollution from air pollution), indoor air pollution caused by water pollution, volatile organic compounds, and laws related to water pollution. 11-00 Papers -Study: Millions in the U.S. Drink Dirty Water (MSNBC News) "More than 20 percent of the nation’s water treatment systems have violated key provisions of the Safe Drinking Water Act over the last five years, according to a New York Times analysis of federal data." "That law requires communities to deliver safe tap water to local residents. But since 2004, the water provided to more than 49 million people has contained illegal concentrations of chemicals like arsenic or radioactive substances like uranium, as well as dangerous bacteria often found in sewage." "Regulators were informed of each of those violations as they occurred. But regulatory records show that fewer than 6 percent of the water systems that broke the law were ever fined or punished by state or federal officials, including those at the Environmental Protection Agency, which has ultimate responsibility for enforcing standards." 12-09 Algae Control in Ponds (GES-Biosys.com) "Archaea often store potassium, sodium, phosphate and other minerals. They have adapted their enzymes so that they often use sodium as a co-factor; rather than the 'trace' minerals used by most bacteria." Clean Water Act and Pollution by State (Scorecard.org) Provides information by state related to the clean water act and pollution. 2-02 Fertilizers Creating a Huge "Dead Zone" in the Gulf (MSNBC News) "The nation's corn crop is fertilized with millions of pounds of nitrogen-based fertilizer. And when that nitrogen runs off fields in Corn Belt states, it makes its way to the Mississippi River and eventually pours into the Gulf, where it contributes to a growing "dead zone" — a 7,900-square-mile patch so depleted of oxygen that fish, crabs and shrimp suffocate." 12-07 Massive Arsenic Poisoning in Bangladesh (CNN News) "A new study published Saturday in the British medical journal the Lancet found that tens of millions of people in Bangladesh have been exposed to poisonous levels of arsenic from contaminated groundwater." See Arsenic Removal 06-10 Microbe Attacks Water Pollution (CBS News) "An industrial chemical that pollutes groundwater and has resisted cleanup can be neutralized by an obscure microbe that researchers have discovered in the Hudson River bottom mud." "In a study appearing Friday in the journal Science, researchers at Michigan State University report a previously unknown bacteria is able to turn trichloroethane, an industrial chemical that is difficult to clear from ground water, into a more benign compound that other microbes can render harmless." 9-03 Phosphates Banned in Dishwashing Detergent (Time.com) "In 2006 the activists managed to push through the first statewide ban on phosphates in household automatic-dishwasher detergents, though it didn't take effect until this year because of an industry compromise. Since then, 15 other states have followed suit. "There was a really broad constituency for the idea of getting these chemicals out of the [wastewater] system," says Rachael Osborn, a public-interest lawyer who worked on the Washington campaign, which has significantly reduced the amount of phosphorus reaching Spokane water-treatment plants." "The slew of state regulations helped lead the American Cleaning Institute (ACI), the trade group that represents most detergent manufacturers, to adopt a voluntary ban this past summer. This means it won't be long before phosphate-laden detergents essentially disappear from U.S. store shelves--a major victory for clean-water advocates." Reduction of Hexavalent Chromium Cr(VI) in Water (Pakistan Research Repository) "Bacterial strains especially (CrT-1, CrT-l3, CrM-l, CrM-3 and S-6) were very efficient in the reduction of hexavalent chromium into trivalent chromium and this activity extenuated in the presence of Eichonzia crassipes plants. Among these three chromium resistant bacteria CrT-1, CrT -13 and S -6 were selected for 16S rRNA gene sequence analysis. Strains CrT -1, CrT -13 and S-6 were isolated from the effluent of tanneries and from chromium contaminated soil. All the three strains were very efficient in the uptake and reduction of toxic hexavalent chromium. Beside this strains were also able to improve the growth of different crops (Triticum aestivum, Helianthus annuus and Vigna radiata) efficiently as compared to others strains from the respective source." Cr(VI) is a by-product of tanneries and making stainless steel. 04-08 Reduction of Hexavalent Chromium Cr(VI) in Water (SpringerLink.com) "Cr(VI)-reducing bacteria are widespread and Cr(VI) reduction occurs under both aerobic and anaerobic conditions." Cr(VI) is a by-product of tanneries and making stainless steel. 04-08 Report: Possible Environmental Contamination Across Great Lakes States (US News) "The investigative group Center for Public Integrity this morning posted bootlegged portions of what appears to be a disturbing—and purportedly suppressed—government report about environmental contamination across the Great Lakes region. Six years in the making, the report assesses evidence of health-threatening contamination in 26 'areas of concern' covering parts of eight states, and it links contamination in many of those areas to high rates of infant mortality, other infant health problems, and adult malignancies, including breast, colon, and lung cancers." 02-08 Solutions for the Environment (Awesome Library - Adams) Provides a summary of key activities necessary to reduce air and water pollution, reduce the rate of global warming, and more. 1-01 Water Contaminants - Pesticides (Environmental Advocates) Provides results from a study of pesticide pollution in the water of New York. Water Pollution - Explanation for Kids (Environmental Protection Agency) Provides information on water pollution for kids. 12-00 Water Pollution Report Card for States (CBS News) "Two environmental groups released a review of government records Tuesday, showing that water pollution enforcement is failing in more than 40 states." "Friends of the Earth and the Environmental Working Group say these states have allowed critically important water pollution permits to expire, effectively issuing industries a license to pollute." "The review also concludes that there is currently little action afoot to correct this serious problem. Nevada, Rhode Island, Oregon and Nebraska all had more than two-thirds of their permits expired. Texas had the largest number of expired permits at 135." 9-03 Water Pollution and Conservation (IAEA.org) Provides an overview of the world water situation. "By the middle of this century: at worst seven billion people in 60 countries will be faced with water scarcity, at best 2 billion in 48 countries, depending on factors like population growth and policy-making." "About 2 million tons of waste are dumped every day into rivers, lakes and streams. One litre of wastewater pollutes about eight litres of freshwater." Water Woes Get Worse in India (Times of India) " No wonder 37.7 million people [in India] — over 75% of whom are children — are afflicted by waterborne diseases every year." 04-08 Purchase Resources Water Pollution (NASA Sample) Provides studies for kids to explore water pollution. 4-00
