LABORATORY ANALYSIS BY TYPE OF FACILITY AND CLASS OF AGRICULTURAL CHEMICAL
An AgESA should be completed on all agricultural chemical-related properties before deciding if cleanup action is needed. Areas where agricultural chemicals were mixed, stored or otherwise handled are likely to be areas of recognized environmental conditions, and may warrant sampling. As part of the AgESA, an inventory of the pesticides and fertilizers that were handled, stored, or mixed on-site must be included to better evaluate what type of sample analysis is needed. The inventory results should be considered in addition to the recommended analysis listed below.

Fungicides; few laboratories have a dedicated fungicide method to screen for fungicides, therefore the MDA recommends analyzing for the following fungicides and metals: benomyl, captan, chlorothalonil, metalaxyl, cadmium, copper, tin, zinc and manganese. |
See MDA guidance document GD26 Analytical Lists for Pesticide Incident Investigations for analytical parameters for MDA Lists 1, 2, and 3.
