Because the subject property was historically used for agricultural purposes, the potential for residual concentrations of pesticides in the near surface soil exists. The use of pesticides likely only involved the routine spraying of crops and no evidence of pesticide mixing, storage or handling was evident from the historical aerial photographs of the Site, and it is our opinion that the use of pesticides has not likely created a Recognized Environmental Condition.
