July 24,2003 <br /> . FINDINGS <br /> PHYSICAL AND CHEMICAL PARAMETERS of SAMPLED GROUNDWATER <br /> Attached sampling data sheets by Del Tech reflect in field measurements from MW <br /> ' Nos 1 through 6 Laboratory Analysis Reports from Sequoia Analytical are <br /> summanzed, with the most recent results (March 24 and June 9, 2003)attached <br /> Reference 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 protect (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 /> and attached in the previous WOS interim 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 This supports a <br /> March 24, 2003 groundwater surface gradient bearing of about 0 0021 FT/FT <br /> declining at an average bearing of N 3 deg W and when measured June 9, 2003 a <br /> groundwater surface bearing gradient of 0 0026 declining at an average bearing <br /> 10 of N 4d" W Over the past four quarters (June 2002 to June 2003) the underlying <br /> shallow water surface dropped about 0 91 FT and there has been a shift in <br /> ' direction of flow to the West of several degrees Findings would be expected to <br /> vary dependent upon season Significant field irrigation pumping appears to be <br /> no closer than 600 FT to the NE and as the surrounding shallow water is thought <br /> ' to be contaminated with bnne (Reference Victor Fine Foods on going study and <br /> on site MW Nos 1 -6 electro conductivity readings) there is a strong likelihood l <br /> that irrigation water in the recent years is extracted from deeper zones <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 /> I <br /> ' 2 California Regional Water Quality Control Board Order No 5-01-057 <br /> Pg 2 <br />
