Our Project Number: E07171A Page 8 of 10 October 31, 2007 The agricultural well located at the center of the property is currently not in use. If left in place, the well may be a conduit for near surface contamination to enter the groundwater aquifer. If water wells are not properly operated and maintained, they can serve as contamination conduits to groundwater. Septic systems may be used for inappropriate disposal of hazardous substances. In this case, there is no evidence to suggest that wells or septic systems may be contaminant pathways on the subject property or vicinity. Although a labor camp was located on the subject property, no evidence of buried debris was observed on the property. 5.0 CONCLUSIONS AND RECOMMENDATIONS Given the historical uses of agricultural chemicals and petroleum products on the subject property, meaningful conclusions regarding the presence or extent of such material cannot be determined without soil sampling and analysis. Such sampling and analysis is especially warranted in the conversion of agricultural land into residential use. One new residence is proposed for this property. Should future residents of the subject property be interested in determining the quality of their drinking water, EHD should be contacted for direction regarding the potential for impacts to groundwater from the agricultural history of the property and vicinity. If the AST is to be used in the future, it should be placed in a secondary containment to prevent soil staining. If the existing structures are to be renovated or demolished, a survey to detect lead-based paints and asbestos-containing materials should be conducted prior to any such activities. The unused agricultural well located at the center of the property near the turbine should be abandoned under EHD oversight. Any other wells or septic systems identified which will not remain in use should also be abandoned under EHD oversight. Any additional infrastructure or buried debris that may be encountered during site grading or development should be removed and disposed of in accordance with all applicable regulations. As the site is developed, any stained soil, buried debris or sources of contamination identified should be characterized and properly disposed in accordance with federal, state, and local regulations.
