Situations that should be tested if there is a concern over environmental problems associated with agriculture.

1. Cultivated farms include citrus groves, orchards, crop farms, tree farms, cotton fields, flower farms, etc.
   

   Soil and groundwater in Cultivated Fields should be tested for pesticides and metals such as Arsenic and Mercury. While Chlorinated Pesticides, such as DDT, Chlordane, Aldrin, Toxaphene and their associated breakdown products are more likely to be detected because of the very slow rates of decay, other pesticides including Malathion, Parathion, etc., and Herbicides including 2,4-D, 2,4,5-T and Roundup can also be tested. The amount of testing locations should be representative of the entire cultivated area, and the number of sampling locations depends on the size of the cultivated fields. Soil and groundwater in the area of existing or former Chemical Buildings and Mixing Areas should be tested for pesticides and herbicides and various metals associated with the chemical compounds. Soil and groundwater around Pump Stations should be tested for petroleum compounds. Groundwater can be collected from temporary monitoring wells and analyzed for components associated with diesel fuel. Soil can be collected and field-analyzed for hydrocarbons with an Organic Vapor Analyzer (OVA) and can be analyzed in a laboratory for components associated with diesel fuel. Soil and groundwater in areas associated with Vehicle and Equipment Maintenance Buildings and Fuel Storage Facilities should be tested. Groundwater can be collected from temporary monitoring wells and analyzed for components associated with petroleum and solvents. Soil can be collected and field-analyzed for hydrocarbons with an Organic Vapor Analyzer (OVA) and can be analyzed in a laboratory for components of petroleum and solvents.

   
   
2. Pasture
   If Dipping Vats were known to have been present, the soil and groundwater around the dipping vat should be tested for pesticides and metals.
