Anderson & Associates, Inc., to a depth of 17 feet <br /> to characterize the soil profile of the proposed septic field as per the requirements of San Joaquin <br /> County Environmental Health Division. No ground water was encountered in the boring. <br /> Generally, soil mixtures of sand, silt, and clay were encountered in the boring.
