Almost half of OECD member countries, including many in Europe, have potentially dangerous nutrient and pesticide concentrations in drinking water sources, a report from the Organisation for Economic Co-operation & Development (OECD) has claimed. Tests carried out on surface water and groundwater monitoring sites in agricultural areas showed these pollutants often "exceed national drinking water recommended limits", said the OECD in its report on the environmental impact of farming. It said: "Of concern is agricultural pollution of groundwater drawn from shallow wells and deep aquifers, especially as natural recovery rates from pollution can take many decades." In the UK, 30 per cent of monitored sites in agricultural areas had nitrates in surface water and groundwater above national drinking water threshold values. The OECD said the annual clean-up bill could be as high as [euro]345 million. Some other countries fared worse: Portugal (37 per cent), Belgium (41 per cent) and the Netherlands (71 per cent). Agriculture was held responsible for more than half the nitrates in surface fresh water in nine European OECD countries: Ireland, Denmark, France, Italy, Poland, the UK, Germany, Belgium and the Netherlands. 3.

Alt Cause – sewageJeantheau 05 – writer for Grinning Planet website [Jeantheau, Mark, “ATOMIC CANNONBALL OFF THE HIGH DIVE” Grinning Planet, September 6, 2005, http://www.grinningplanet.com/2005/09-06/water-pollution-causes-article.htm]In developing countries, an estimated 90% of wastewater is discharged directly into rivers and streams without treatment. Even in modern countries, untreated sewage, poorly treated sewage, or overflow from under-capacity sewage treatment facilities can send disease-bearing water into rivers and oceans. In the US, 850 billion gallons of raw sewage are sent into US rivers, lakes, and bays every year by leaking sewer systems and inadequate combined sewer/storm systems that overflow during heavy rains. Leaking septic tanks and other sources of sewage can cause groundwater and stream contamination. Beaches also suffer the effects of water pollution from sewage. The chart below shows the typical reasons that about 25% of the beaches in the US are put under water pollution advisories or are closed each year. It's clear that sewage is part of the problem, even in what is supposedly the most advanced country in the world. Ext – Alt CauseThere are too many causes of water pollution to solve –A. personal care productsJeantheau 05 – writer for Grinning Planet website [Jeantheau, Mark, “ATOMIC CANNONBALL OFF THE HIGH DIVE” Grinning Planet, September 6, 2005, http://www.grinningplanet.com/2005/09-06/water-pollution-causes-article.htm]Whenever we use personal-care products and household cleaning products—whether they be laundry detergent, bleach, or fabric softener; window cleaner, dusting spray, or stain remover; hair dye, shampoo, conditioner, or Rogaine; cologne or perfume; toothpaste or mouthwash; antibacterial soap or hand lotion—we should realize that almost all of it goes down the drain when we do laundry, wash our hands, brush our teeth, bathe, or do any of the other myriad things that incidentally use household water. Similarly, when we take medications, we eventually excrete the drugs in altered or unaltered form, sending the compounds into the waterways. Studies have shown that up to 90% of your original prescription passes out of you unaltered. Animal farming operations that use growth hormones and antibiotics also send large quantities of these chemicals into our waters. Unfortunately, most wastewater treatment facilities are not equipped to filter out personal care products, household products, and pharmaceuticals, and a large portion of the chemicals passes right into the local waterway that accepts the treatment plant's supposedly clean effluent. Study of the effects of these chemicals getting into the water is just beginning, but examples of problems are now popping up regularly:Scientists are finding fragrance molecules inside fish tissues.Ingredients from birth control pills are thought to be causing gender-bending hormonal effects in frogs and fish.The chemical nonylphenol, a remnant of detergent, is known to disrupt fish reproduction and growth. B. plasticJeantheau 05 – writer for Grinning Planet website [Jeantheau, Mark, “ATOMIC CANNONBALL OFF THE HIGH DIVE” Grinning Planet, September 6, 2005, http://www.grinningplanet.com/2005/09-06/water-pollution-causes-article.htm]Plastics and other plastic-like substances (such as nylon from fishing nets and lines) can entangle fish, sea turtles, and marine mammals, causing pain, injury, and even death. Plastic that has broken down into micro-particles is now being ingested by tiny marine organisms and is moving up the marine food chain. Sea creatures that are killed by plastic readily decompose. The plastic does not—it remains in the ecosystem to kill again and again. C. sedimentJeantheau 05 – writer for Grinning Planet website [Jeantheau, Mark, “ATOMIC CANNONBALL OFF THE HIGH DIVE” Grinning Planet, September 6, 2005, http://www.grinningplanet.com/2005/09-06/water-pollution-causes-article.htm]When forests are "clear cut," the root systems that previously held soil in place die and sediment is free to run off into nearby streams, rivers, and lakes. Thus, not only does clearcutting have serious effects on plant and animal biodiversity in the forest, the increased amount of sediment running off the land into nearby bodies of water seriously affects fish and other aquatic life. Poor farming practices that leave soil exposed to the elements also contribute to sediment pollution in water.
