The widespread use of pesticides for agricultural and nonagricultural purposes has resulted in the presence of their residues in surface and ground water resources.  Farmland irrigation will contaminate groundwater with pesticides. Irrigation increases the risk that pesticides will migrate to ground water and surface water. Irrigation of saturated soil or at a rate that exceeds the rate of soil penetration promotes runoff from portable pesticides. Irrigation that promotes the frequent downward movement of water beyond the root zone of plants also promotes the leaching of substances including pesticides to ground water.  In addition, farmland is often well drained and natural drainage is often enhanced by land drains. Water from excessive rainfall and irrigation cannot always be held within the soil structure. Therefore, pesticides and residues (also nitrates and phosphates) can be quickly transported to contaminate ground water and freshwater supplies over a large geographical area. Generally, pesticide contamination of surface water in a particular region depends on several factors, such as closeness of crop fields to surface water, characteristics of surrounding fields (soil, grassland, slope, and distance to water bodies), the properties of the pesticide, climate conditions (temperature, humidity, wind, and precipitation) and management practices.  The health effects of pesticides depend on the type of pesticide. Some, such as the organophosphates and carbamates, affect the nervous system. Others may irritate the skin or eyes. Some pesticides may be carcinogenic (cancer causing). Others may affect the hormone or endocrine system in the body. The EPA has drinking water regulations for more than 90 contaminants. Therefore, it is necessary to test pesticide residues in water.
