Agricultural Environmental Site Assessment (AgSA) Gudiance Document Attachment 1


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.

TYPE OF FACILITY TYPE OF ANALYSIS RECOMMENDED
Ag retailers & Applicators MDA Lists 1 & 2, Fert
Greenhouses MDA List 3, Fert, EPA Method 8081, Fung
Exterminators & Related MDA List 3, EPA Method 8081, EPA Method 8141
Aerial applicators MDA Lists 1, 2, & 3, dinoseb, EPA Method 8141
Lawn care companies MDA Lists 1 & 2, Fert, EPA Method 8141
Grain Elevators, Seed Storage MDA List 1, mercury, carbon tetrachloride, Fung
Orchards, Truck Gardens MDA List 1, EPA Method 8081, arsenic, lead, Fert
Golf Courses MDA List 1, primary pesticides, heavy metals
Key:  
MDA List 1 Neutral pesticides
MDA List 2 Acid pesticides
MDA List 3 Carbamate pesticides
Fert Fertilizers: recommend analyses are nitrate nitrogen and total Kjeldahl nitrogen
EPA Method 8141 Organophosphate pesticides
EPA Method 8081 Chlorinated pesticides
Fung 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.
