The ground water sample collected from the site domestic well was transported to Associated Laboratories of Orange, California, a State of California Department of Public Health-certified analytical laboratory for analysis. The sample was analyzed for: • Nitrate as NO3 by EPA Method 300.0; and • 1,2-Dibromo-3-chloropropane (DBCP)by EPA Method 504.1. 4.5. ANALYTICAL RESULTS OF GROUND WATER Nitrate as NO3 was reported in the groundwater-sample collectedfrom the site.domestic well.at 8 73 mill-glr.= r h {#gll)�DBCP was reported at.0:37 microgramsper,liters(µg/1} in the ground i E water sample collected'ftom the'site�domesticcMell. The results for both Nitrate as NO3 and DBCP were similar to the results from the sampling in 1999. The laboratory report(Associated Laboratories Lab Project.No.985011),quality assurance/quality control report and chain-of-custody form are included in Appendix E. 5.0. SOIL PROFILE On 27 March 2009, an Onsite Wastewater Treatment System Permit was issued by the SJCEHD (Appendix D)for the above referenced property. On 30 March 2009,a 4-inch diameter hand auger was utilized to advance a percolation test hole to 42-inches bsg in the site parcel. I i 5.1. SITE MAP The site plan(Figure 2)includes the location of specific site features (i.e., structures,drives,wells, septic systems, large trees, pastures, pools, natural drainage courses, ponds, waterways, etc.). A percolation test hole location map showing the approximate location of percolation test hole(TH-1) is illustrated on Figure 3. A precise description of the location and construction of the percolation test hole TH-1 is included in Appendix D (SJCEHD form 42-03). The soil suitability study was conducted within 100-feet of the proposed location of the septic system. Advanced GeoEnvironmental,Inc.
