Abstract |
The Ground Water Technology Section, Office of Pesticide Programs, EPA, evaluated the available aldicarb ground-water monitoring data using methods outlined in the 'Aldicarb Special Review Document' of 1988. The number of wells, nationwide, containing aldicarb and aldicarb residues were categorized according to the old Maximum Contaminant Level (MCL) of 10.0 ppb and the new MCL of 3.0 ppb. The number of wells exceeding the 3.0 ppb MCL was determined. Counties with aldicarb residue detections were ranked 'Low', 'Medium' or 'High' based on the potential for aldicarb to leach to ground water. |
