It appears, and is generally accepted, that the groundwater is flowing in a northwest direction toward the San Joaquin River; however, at the intersection of Small Road and French Camp Road, the groundwater flow appears to be in a northeast direction. The 1999 Lines of Equal Depth Map illustrate the groundwater depth to be 25 feet below ground surface. A Well Driller's Log for Mr. Barber's domestic well at 10411 South Small Road was available to illustrate the underlying soil lithology. Interestingly, the well log shows from 5 � eet b a a�P Consequently, perched water table conditions probably do not exist at higher elevations than the existing water table. From the 57-foot depth on down to the well depth of 160 feet, there are intervening strata of sand and clay. There is the highly remote possibility of the surfacing of effluent from inundated conditions caused by flooding; however, the porosity of the subsurface soils as evidenced from the percolation test results should allow for adequate drainage,provided the underlying clay stratum does not become saturated. The subject property is not subject to the 100-year flood. As referenced above, no water sample was tested for nitrate and the agrichemicals DBCP/EDB since there is no well on the subject property. It will be a re ui from each individual well before itc comnletinn. If high nitrates and/or DBCP are found ill1le-- /,-i,v t st w e affected well may have to be drilled eo a dee th.

High nitrate impact to the shallower aquifers and significantly lower nitrate concentrations in the deeper aquifers is often observed throughout San Joaquin County. The agrichemicals DBCP and EDB are typically below detection limits (BDL) in this locale. Five domestic wells and one irrigation well surround the property and are denoted on the USGS Map found in Appendix"A." Chesney Consuftittg
