Nevada Certified Pesticide Applicator Pracitice Practice Exam

Groundwater contamination specifically refers to the leaching of pesticides into groundwater. This occurs when pesticides applied to the surface of the soil pass through the soil layers and filter down into the aquifers or underground water supplies. This process can happen when pesticide application rates are excessive, when there is heavy rainfall, or when the pesticides are not effectively contained within the intended application area. Groundwater is a critical resource for drinking water and agricultural use, so contamination poses significant risks to health and the environment. Understanding this concept is essential for managing pesticide application practices responsibly to mitigate the risk of groundwater contamination.
