(3.2)Possible Septic Contamination: Existing San Joaquin County Environmental Health Department records of twelve(12) septic system permit installations along North Mackville Road were reviewed and are summarized in the attached "San Joaquin Co. Environmental Health Divisions Septic Permit Records" study, which contains permit nos., dates, names and addresses, soil type and leach field and pits system installations information. The records reviewed covered about a thirty-three (33)year period from November 25, 1970 through October 1, 2003. Two(2) of the records was for adding to the existing systems and another record was for repairing an existing system installation. The remaining nine(9)other permits were for either pit or sump installations. Six(6)of the permits listed the soil as hardpan.

Even though most of the soils listed had slow permeability character, only two(2) permits were for repairing an existing installation. Another one (1)was for adding on to an existing system. Nine (9)of the twelve(12)pit installations served satisfactorily and did not have to be repaired or replaced. Historically pit septic systems and sumps have / served satisfactorily in the area of the subject property. r (3.3) Possible Nitrate and DBCP Pollution: No animals were seen on the subject property so there does not appear to be any undue nitrate concentrations because of an overpopulation of animals.
