Subsurface contamination of known or unknown contaminants may be possible,particularly naturally occurring nitrate concentrations,as referenced. Surrounding agricultural ,produce land-may-be-eontributing-nitmte4o-the under_lying_aquifer&—, §3.4 Description of all past off-site potential and/or known above and below ground sources of contamination identified in the area of the project site that could impact the site include: Information conveyed by the ERS documents indicate no listings, with an almost impossible likelihood of impact to the property from a distant contaminated site. The GeoTracker document illustrate no listings on the property or within a one mile radius from the property. The closest Leaking Underground Fuel Tank(LUFT)is listed as "closed." There is a permitted Underground Storage Tank approximately one mile to the southwest. As referenced, agricultural spray drift affecting the property from the nearest agricultural production land could be an extremely slight possibility, since agricultural production occurs upgradient to the property with regard to wind shed. § 3.5 Descriptions of all current off-site potential and/or known above and below ground sources of contamination identified in the area of the project site include those referenced in Sections 3.2, 3.3, and 3.4 above. Any contaminated sites can be considered"past"off-site sources of contamination that are simultaneously"current" contaminated sources. § 4.0 EVALUATION OF PAST AND CURRENT SOURCES OF CONTAMINATION IDENTIFIED AT OR NEAR THE SITE AND RECOMMENDATIONS FOR FURTHER ACTION § 4.1 Evaluation of each potential and/or known source of contamination identified in the above Sections have been discussed in the respective Sections to facilitate the transfer of information to the reader. § 5.0 CONCLUSIONS AND RECOMMENDATIONS § 5.1 Evaluation of each point-source potential contamination described (i.e., on-site septic tanks, on-site propane tank) and non-point sources (i.e., on-site and surrounding agrichemical applications, and nitrate in the underlying groundwater)pose an extremely low risk to the subject property and to human health. Septic system density in this locale is sparse. Consequently,the degree of nitrate impact to the property from this source can also be considered extremely low. Greater nitrate impact originates from agricultural fertilization which surrounds the property. Chesney Consulting
