[5] Continued. <br /> Nitrate and DBCP analyses for an on-site well was provided to our firm. The results indicate a non- <br /> detect (ND) for DBCP, and a comparatively high level of nitrate concentration at 38 ppm. The <br /> Maximum Contaminant Level (MCL) as mandated by the California Department of Health Services <br /> and the U.S. Environmental Protection Agency is 45 ppm for nitrate. The tested nitrate concentration <br /> illustrates there has been some impact upon the local groundwater from either agricultural practices <br /> such as nitrogen applications, or from septic systems within the proximity of the sampled well. <br /> [61 PROPOSED SEPTIC TANK SIGHTING AND USAGE <br /> The deep, fairly sandy soil structure of the subject parcel is conducive for effluent permeability. The <br /> proposed residential development and related septic system is certainly acceptable with this site. All <br /> recommended sewage disposal areas are in compliance with the regulations of the San Joaquin <br /> Department of Environmental Health. Any sewage disposal area must conform with all of the <br /> "distance" separation requirements from applicable objects. <br /> 4 <br /> - �e (,)uality Control Inspection <br />
