3.6 Discussion of General Area Septic Tank Repair History: Repair history of the septic tanks in this area reveals that the leach lines and seepage pits have resulted in consistent unerring performance. This is based on the fact that no septic system repair application has been applied for. 3.7 Description of Proposed or Expected Maximum (including second unit dwellings) septic tank usage on site. The four parcels will have only primary residences, no second unit dwellings are planned. Thus only one septic system per parcel is anticipated at this time. Per County ordinances, each parcel on this map is entitled to one primary residence and one second unit dwelling. Therefore this project could ultimately have 8 homes on the four proposed parcels. 4.0 GROUNDWATER INFORMATION SECTION: 4.1 Description of the depth and gradient of groundwater in the general area: The depth to ground water in this area is approximately 140 feet according to the map of"Lines of Equal Depth to Groundwater" published Spring, 1999,by the San Joaquin County Flood Control and Water Conservation District. The gradient descends from east to west. 4.2 Description/Discussion of any existing and/or potential groundwater contamination issues in the general location of the site: The concerns for groundwater contamination in this area is deemed low due to the depths involved. Insecticides, pesticides, and fertilizers typically do not impact groundwater at these depths,however, as with any agricultural area,there is always potential for contamination due to chemicals used in the farming operation. 4.3 Description of location,type and construction of well and location where water sample(s)were obtained: Water samples were taken from a spigot on a domestic well at the house located at 22333 E. Navarro Court on May 5, 2005 by Louie Mendez of Dillon&Murphy. The water samples were obtained at this location due to the fact there are no outlets for water on the project site. The sample site is adjacent to the project site. 4.4 Description of constituents being tested for in the water sample: The water samples are being tested for nitrates and DBCP. The results for dibromochloropropane (DBCP)were non- detected and the results for nitrates were also non-detected. 4.5 Description of how sample was obtained, handled, stored, and transported to the lab: The water samples were obtained from the spigot at the house located 22333 E. Navarro Court. The samples were taken by Louie Mendez of Dillon&Murphy, and driven directly to Precision Enviro-Tech. The samples were taken and handled in accordance with Precision Enviro-Tech requirements. The results from the test can be found in the Appendix. 4.6 Complete Chain of Custody document, including printed and signed name of third party sampler, condition of sample and date and time the sample was submitted to the lab. For Laboratory samplers, complete laboratory report to include the above noted information: The complete chain of custody document is located in the Appendix. 2 c:\0466\Soil Report
