Vander Meulen Property,APN 207-200-09 Page 8 J Our Project Number: E07101A July 3, 2007 1 5.0 CONCLUSIONS AND RECOMMENDATIONS Given the historical uses of agricultural chemicals and etroleu products on the subject property, meaningful conclusions regarding the presence. or extent f such material cannot be,,---'/determined without soil sampling and analysis. Suc sampling and analysis is especially F1warranted in the conversion of agricultural land into sidential/use, as is the case for this property. FiShould future residents of the subject property be interested in determining the quality of their / drinkingwater, EHD should be contacted for direction regarding the potential for impacts tom 9 9 Fgroundwater from the agricultural history of the property and vicinity. The surface staining under the farm equipment and elevated truck should be cleaned up. F1The staining around the portable fuel tanks should be cleaned up, and the tank should be placed within secondary containment when not in use to prevent further soil staining. All drums, buckets and other chemical containers should be placed within secondary containment. In all stained locations, if contamination deeper than 2-3 inches below ground surface is identified, an environmental professional should be retained to oversee the cleanup. If the property owner or the EHD are concerned about potential itrate oblems on the subject property from its past and current uses for raising domestic als, oil samples could be collected and analyzed to determine soil quality. ny wells r septic systems identified which will not remain in use should I�abandone under FiEHD ove ght. Any additional infrastructure or buried debris that may be a ountere during it gra ing or development should be removed and disposed of in accor aTr�with all ap le regulations. As the site is developed, any stained soil or sources of contamination identified should be characterized and properly disposed in accordance with federal, state, and local regulations. 6.0 LIMITATIONS This report was compiled as a Surface and Subsurface Contamination Report for the subject property. This report contains information and data provided to NOA by several sources. NOA in no way warrants the accuracy or completeness of the information provided to this investigation by those sources. It should be noted that when an environmental assessment is completed without sample collection and quantitative analysis of soil and groundwater beneath the site, as in this study, i no statement of scientific certainty can be made regarding latent subsurface conditions which may be the result of on-site or off-site sources. The findings and conclusions of this report are not scientific certainties, but rather, probabilities based on professional judgement concerning NEIL O.
