16 <br /> FINDINGS <br /> ' PHYSICAL AND CHEMICAL PARAMETERS of SAMPLED GROUNDWATER <br /> Attached sampling data sheets by Del Tech reflect infield measurements from MW <br /> Nos 1 through 6 Laboratory Analysis Reports from Sequoia Analytical are <br /> ' summarized, with the most recent results (December 29, 2003) attached Reference <br /> ATTACHMENT 3, ANALYTICAL LABORATORY FINDINGS <br /> ' PHYSICAL PARAMETERS <br /> The WOS site is within the area represented by existing Monitoring Wells <br /> ' associated with the ongoing Victor Fine Foods Property project2 (Victor) Attention <br /> is directed reference the Victor Fine Foods Monitoring Well Field Parameter <br /> Information for the March 1, 2002 samplings, extracted from CVRWQCB records <br /> iand attached in the previous WOS intenm report by this report's author <br /> Within the immediate site area, ground water surface gradient information has <br /> ' been supplemented with depth to water findings taken from the newly installed <br /> monitoring wells The information is included in ATTACHMENT 5, <br /> GROUNDWATER GRADIENT and BEARING CALCULATION Over the past <br /> ' five quarters (September 2002 to December 2003) the underlying shallow water <br /> surface dropped about 1 60 FT and there has been a shift in direction of flow to <br /> the East of several degrees Findings would be expected to vary dependent upon <br /> season Significant field irrigation pumping appears to be no closer than 600 FT <br /> to the NE and as the surrounding shallow water is thought to be contaminated <br /> with bane (Reference Victor Fine Foods on going study and on site MW Nos 1 -6 <br /> electro conductivity readings) there is a strong likelihood that irrigation water in the <br /> recent years is extracted from deeper zones <br /> Concurrently with the November 2003 Cone Penetration Testing and the <br /> December 2003 Quarterly Monitoring Well Testing the agricultural well located <br /> ' about 105 FT east of MW 6 was sampled at the direction of San Joaquin County <br /> Environmental Health Departments representative The well, of unknown <br /> construction, did not yield any hydrocarbons As past results had been <br /> ' confounded, two separate laboratories were utilized <br /> ' TOC elevations referenced for depth to water and assumed elevations below <br /> ground surface (bgs ) were adjusted to a common datum used by the Victor Fine <br /> Foods study The datum was assumed valid and applied to the study by Barber <br /> ' for direct correlation between studied elevations <br /> 2 California Regional Water Quality Control Board Order No 5-01-057 <br /> 2 <br />
