Surface and Subsurface Contamination Report ******* APN: 24R-220-T7 7 **' '*Parcel Nos. 1, 2,&3 From 29 to 33 inches depth,the soil is brown in color, very hard and firm, sticky and plastic with few fine roots. From 33 to 60 inches dept the soil is brown in It is 75 to 90 percent silica- cemented within the matrix.

The subject property is in an area known to contain<20 parts per million Nitrate (NO3). The State Standard for safe drinking water that has been established for Nitrates (NO3)is 45 mg/L. A binder entitled"Underground Tank Site Mitigation Database List" also available in the Environmental Health Department's office was consulted and no underground tanks were listed in the binder for the subject property. DBCP,Nitrates and underground tanks do not appear to be significant contamination contributors to the subject property. Mitigation Measures: A limited number of animals were found on the subject property, so no excessive nitrate concentrations are anticipated from animal overpopulation. Also the San Joaquin County Environmental Department's"Nitrate--Land Use Map" concentrations do not indicate an undue concern over nitrate pollution. No correction for excess nitrate concentration is recommended j No chemical residues or spillage of hazardous material or improper storage was I noted. The San Joaquin County Agricultural Commissioner's Office report revealed that the property owner has applied no chemicals on the subject property to produce agricultural crops. So no chemical pollution is anticipated from agricultural use. j Tna T. rhitra Tr ------l(UQU T1istra T.nne.-----(Ink lata-----ralifnrnin 95 iFil fi
