Back to Identifying Potential Pesticide Contaminants

As mandated in the Pesticide Contamination Prevention Act (PCPA), DPR adopted the following regulations to enable the identification of agricultural pesticides that have the potential to pollute ground water.

Specific Numerical Values

Mobility and persistence thresholds established in regulation are used as the first step in the identification of potential pesticide contaminants.

Groundwater Protection List

The ground water protection list consists of agricultural pesticides that exceed Specific Numerical Values for mobility and persistence and are intended to be applied to or injected into the soil by ground-based application equipment or by chemigation, or the label of the pesticide requires or recommends that the application be followed, within 72 hours, by flood or furrow irrigation.
