Surface and Subsurface Contamination Report****APN: 055-170-11****Parcel Nos.1, 2 and 3 9 APN: 055-250-27 The "DBCP—Land Use Map shows the subject property to be in an area where DBCP concentrations are known to be equal to or greater than 0.2 ppL. The "Nitrate—Land Use Map" shows the subject property to be in an area containing 21 to 44 ppm. nitrate concentrations. . A potential need for contamination mitigation measures on the subject property was encountered when the binder entitled"Underground Tank Site Mitigation Database List", available in the Environmental Health Department's office, was consulted which listed the address for the subject property as needing such measures. However, further research, study and contacts with representatives of the San Joaquin County Environmental Health Department and the Central Valley Regional Water Quality Control Board, which was listed as the lead agency for seeing that the possible contamination be corrected, resulted in the subject property was not being a site needing any kind of mitigation measures. Neither of these agencies had any knowledge of the site as needing mitigation measures, as well as,there were no recorded needs for mitigation measures on the subject property in their records and files. The property owner was also consulted and he had no knowledge of any such need for mitigation measures. Further, no underground tanks or contaminated soil were encountered during my field search. Well Water Analysis: A well water analysis was reported in my Soil Suitability Study for MS-98-18, approved on August 6, 1998 and is acceptable for the subject property's land use application number PA-02-347(MS)as stated in San Joaquin Environmental Health Department's letter dated August 28,2002. The well water Nitrate (NO3)and DBCP concentrations reported in my Soil Suitability Study for MS-98-18 are as follows: Maximum Chemical Constituent Contamination Test Dibromochloropronane (DBCP) Nitrate(NO3) Level WWI-] fmg/L1 1u9JLI ImPJLI Domestic Wells Parcell 0.88 56.4 0.2 45 3400 Kingdon Road -. Parcel 2.10 78.8 0.2 45 Southwest Comer Irrigation Well Parcel 0.92 22.2 0.2 45 Only the Nitrate(NO3)concentration for the irrigation well on Parcel 2 is within the State's standards established for safe public drinking water at 45 mg/L. All the rest of the test results for Dibromochloropropane(DCP) and Nitrate (NO3)concentrations for the other wells on the subject property exceed the State's standards for safe public drinking water established at 0.2 ug/L and 45mg/L for DBCP and NO3 respectively.
