Surface and Subsurface Contamination Report—APN: 009-100-02—To create four(4)parcels containing 80 acres each within an existing 320 acres parcel state. The subject property is situate remote from any businesses, commercial and industrial pursuits and so is not likely to be subjected to any off site contamination contributors. The Maps entitled"DBCP and Nitrate—Land Use"available in the Environmental Health Department's office also show that the subject property is in the midst of an area not known to have significant Dibromochloropropane (DBCP)and Nitrate(NO3) concentrations. According to the aforementioned DBCP and Nitrate maps, the Subject property will not be subjected any undue contamination from off-site sources. (4)Evaluation of Past ad Current Sources of Contamination Identified At Or Near The Site And Recommendations For Further Action (4.1)Evaluations: Each of the past, present and current sources of contamination are evaluated in each of the Sections 3.1 through 3.6 above. Refer also to Sections 5.1 through 5.3 below. (5) Conclusions.Recommendations and Mitigation Measures: (5.1)Conclusions: With very limited animals being found on the subject property,no excessive nitrate concentrations are anticipated from animal overpopulation and no correction for excess nitrate concentration is needed on account of animals. An insignificant amount of recorded septic system failures were found in the septic system research contained in this report so there is no anticipation of septic system type contamination problems developing if the type of systems installed in the past are maintained. There does not appear to have been any subsurface construction present or past that would contribute to below ground contamination. For the past many years the subject property has been subjected only to the agricultural use of producing grape crops. Since the San Joaquin County Agricultural Commissioner's report showed the property owners have been adhering to all the standards of agricultural permit and chemical applications restrictions,there does not appear to be any undue concern from chemical use in grape crop production. Also the DBCP and Nitrate(NO3)—Land Use Maps available in the San Joaquin Environmental Health Department's Office showed no real detrimental concerns for these two chemical concentrations. The well water test results also did not reveal any detrimental chemical product contamination. The well water sampling and testing results meet current California primary drinking water standards, for Dibromochloropropane (DBCP)and Nitrate(NO3). Also the chemicals normally used in the production of grape crops are not generally known to create hazardous problems in the general area of the subject property. There is no indication that contamination problems will develop from chemical contamination due to agricultural crop production.
