PMEP

Script:
Conditions of the site also influence leaching of pesticides. The most important condition is depth to groundwater. Less filtering by the soil occurs for a shallow aquifer. Therefore, there is less opportunity for degradation or adsorption. In humid regions where groundwater may be a few feet below the surface of the soil, where rainfall is high, and where soils are permeable, water carrying dissolved pesticides may take only a few days to percolate to groundwater.
