r7A ter sample from the onsite well indicates a nitrate-nitrogen concentration at 15.5 mg/L; 1.5x over <br /> CL. Given the large amount of surrounding agricultural production and subsequent nitrogen <br /> fertilizer use, this concentration would be expected to be higher. A new, deeper well is proposed to <br /> be installed for the new residence. <br /> In rural areas, it is recommended that bottled water be consumed for drinking and cooking purposes. <br /> LIMITATIONS <br /> The findings, opinions, calculations and conclusions of this report are based upon information from <br /> standard engineering and analytical test procedures, contemporary scientific literature and agency <br /> consultations. Information used in these studies is deemed reliable by the sources from where it was <br /> obtained. <br /> This report is based upon current scientific knowledge to assess factors which are extremely variable <br /> and complex within the environment. Although there are several methods to predict environmental <br /> impact from a septic system, San Joaquin County Environmental Health Department Onsite <br /> Wastewater Treatment System Standards and requirements have been employed for these purposes, <br /> and for this project.
