Prevention of groundwater contamination by agricultural
chemicals requires an understanding of the complex
processes that control pesticide movement below the soil
surface. Through this understanding it is possible to try
to predict which areas may be most vulnerable to
contamination. The many models that have been developed to
characterize pesticide...

Four factors govern the potential for groundwater
contamination by pesticides passing through the soil:
• Properties of the soil
• Properties of the pesticide
• Hydraulic loading on the soil
• Crop management practices
The procedure described in this publication helps
you assess the potential for any specific pesticide
to travel through any specific soil to reach
groundwater.
