Surface and Subsurface Contamination Report—APN: 009-110-04--To create a homesite parcel contain- <br /> ing five(5)acres within an eadsting forty(40)acres parcel leaving a thirty-five acres parcel,Parcel 2. <br /> An insignificant amount of recorded septic system failures were found in the <br /> septic system research contained in this report so there is no anticipation of septic system <br /> type contamination problems developing if the type of systems installed in the past are <br /> maintained. <br /> There does not appear to have been any subsurface construction present or past <br /> that would contribute to below ground contamination. <br /> For the past many years the subject property has been subjected only to <br /> agricultural use or left to its irrigated natural state. Since the San Joaquin County <br /> Agricultural Commissioner's report showed no use of adverse chemicals,there does not <br /> appear to be any undue concern from chemical use in any agricultural endeavors. <br /> Also the DBCP and Nitrate (NO3)—Land Use Maps available in the San Joaquin <br /> Environmental Health Department's Office showed no real detrimental concerns for these <br /> two chemical concentrations. The Far West Laboratories well water test results also did <br /> not reveal any detrimental chemical product contamination. The well water sampling and <br /> testing results meet current California primary drinking water standards, for <br /> Dibromochloropropane(DBCP) and Nitrate (NO3). <br /> Also there is no indication that contamination problems are present from <br /> heroical contamination due to agricultural crop production. <br /> (6.2) Mitieation Measures: No chemical residues or spillage of hazardous materials <br /> were noted on the subject property. However, some abandoned batteries were noted �� <br /> stored on the subject property which need to be removed and disposed of at an approved <br /> hazardous waste disposal site or sold to a battery supply business such as Lodi Battery <br /> Company at 1730 Ackerman,Lodi California. <br /> (6.3)Recommendations: Continuing the present conditions and use on the subject <br /> property and developing the subject property a is n 7cted to impact ground <br /> water nor cause other health hazards. <br /> Walter E.
