1 Stockton East Water District and the Lagomarsino Brothers facility. Underground storage tanks located at these facilities have been documented and there have been no reported leaks at these facilities. The third facility is the Econo #05748 service station. This station did have USTs which leaked and impacted the underlying aquifer. But as referenced under the Remediation Status,this case has been closed by the Regional Water Quality Control Board. The fourth facility is the Marley Cooling tower Company. This facility has significant groundwater contamination. Records were obtained from the San Joaquin County Environmental Health Department which illustrate the contamination plume and groundwater monitoring and remediation. The attached "Well Location Map" indicates the subject properties with a starer. The groundwater gradient, and therefore the contaminant plume are towards the southwest. It appears the subject properties have not been impacted from the contaminant plume based upon the location of the monitoring/remediation wells. If it is found in the future that there is contamination under the subject properties from the Marley Cooling Tower Company,they would be legally obligated to remediate the groundwater. INFORMATION FROM SITE RECONNAISSANCE The subject property appears to contains no underground storage tanks(USTs). Evidence for USTs would include dispensing hoses and/or pumps, risers, or vent pipes. There are no above ground tanks (ASTs). The subject property was surveyed for the following which may be evidence for surface and/or subsurface contamination: There are no transformers on-site; therefore,there is no concern from polychloride biphenyl (PCB) contamination. Nor was there any evidence of solid waste disposal, other than discarded tires on Parcel 2 of Site#2. Both sites were inspected for environmental concerns originating from discolored, disturbed or subsided soils, stressed vegetation(other than what would be considered normal), and unusual or noxious odors. None were observed. An important concern associated with the environmental assessment of properties is the issue of buried pesticide or other types of containers. It was an occasional practice to dispose of containers by this method many years ago. Detection of these types of underground artifacts is difficult-to-impossible even with the use of ground penetrating radar or other types of non- intrusive, subsurface analyses. The land surface did not exhibit visual indicators for buried containers such as surfacing of product residue, soil mounding or soil depressions. The static groundwater is found approximately 70 feet under the property. This is considered a comparatively deep elevation in relation to other parts of the County. Groundwater at this depth is not easily impacted from pesticides or nitrogen in the form of nitrates. The on-site soils consist of a medium to high clay content soil which can attenuate agrichemical residue in comparison to a sandy soil. 2 Of Quality Coontrol Inspection
