Pesticides In Ground Water and Drinking Water

What is pesticide? Pesticides are chemicals used to kill pests, especially insects. Insecticides are also known as fungicides. Most agricultural chemicals are sprayed as sprays, but sometimes powdery or pelleted pesticides can be seen. Pesticides are used in a variety of things from crops such as corn, barley, wheat to plants such as petunia, calendula, rhododendrons and rhododendrons. What is groundwater?

Pesticides present in groundwater and drinking water have a big influence, they are expensive and have administrative problems. For example, the total concentration of residual pesticide in many groundwater supplies in the EU countries exceeds the maximum permissible concentration. In the United States, the same situation, when investigating about 68,000 wells, we found that about 9,000 wells were actually contaminated with residues and exceeded the drinking water of the Environmental Protection Agency (EPA). (Hond, Frank et. Al. 2003)

Insecticides are included in samples of groundwater, surface water, and drinking water throughout the United States. Fish death by pesticides is observed throughout the country. "Some water systems, especially corn belt type water systems, have pesticide concentrations far in excess of drinking water standards" (Barrett 17). Concerns about the inundation of pesticides into groundwater are rising nationwide after the detection of certain residual pesticides in well water samples. "So far, Atrazine has the highest detection rate in groundwater in Indiana ... Atrazine and its metabolites can have a negative health consequence for humans and wildlife species (Barrett 55)

Nutrition pollution can affect important groundwater sources and drinking water. Surface water such as lakes, rivers and streams supplies drinking water to about 170 million people in the United States. Some of these water are affected by excessive nitrogen and phosphorus, and others are affected. Groundwater is soaked in soil and groundwater, and about 90 million people depend on groundwater for drinking water. When groundwater passes through soil, it absorbs nitrogen and phosphorus and carries it to the surface of the groundwater. This contaminated water enters a public drinking water system or a private well, where it can pose a serious public health threat. Public drinking water systems can withstand the tremendous economic burden of processing nutrient-contaminated drinking water.
