• FINDINGS PHYSICAL AND CHEMICAL PARAMETERS of SAMPLED GROUNDWATER Attached sampling data sheets by Del Tech reflect in field measurements from MW Nos 1 through 6 Laboratory Analysis Reports from Sequoia Analytical are summarized, with the most recent results (September 17, 2004) attached Reference ATTACHMENT 3, ANALYTICAL LABORATORY FINDINGS PHYSICAL PARAMETERS The WOS site is within the area represented by existing Monitoring Wells associated with the ongoing Victor Fine Foods Property project2 (Victor) Attention is directed reference the Victor Fine Foods Monitoring Well Field Parameter 1 Information for the March 1, 2002 samplings, extracted from CVRWQCB records and attached in the previous WOS interim report by this report's author i Within the immediate site area, ground water surface gradient information has been supplemented with depth to water findings taken from the newly installed monitoring wells The information is included in ATTACHMENT 5, jGROUNDWATER GRADIENT and BEARING CALCULATION When measured in late September, the gradient of the groundwater surface remains at about 0 002 FT/FT to the northeast Since December 2000 to September 2004 the underlying shallow water surface dropped about 6 7 FT and there has been a shift in direction of flow to the east of several degrees Findings would be expected to vary dependent upon season Significant field irrigation pumping appears to be no closer than 600 FT to the NE and as the surrounding shallow water is thought to be contaminated with brine (Reference Victor Fine Foods on going study and on site MW Nos 1 -6 electro conductivity readings) there is a strong likelihood that irrigation water in the recent years is extracted from deeper zones I Concurrently with the November 2003 Cone Penetration Testing and the December 2003 Quarterly Monitoring Well Testing the agricultural well located about 105 FT east of MW 6 was sampled at the direction of San Joaquin County Environmental Health Departments representative The well, of unknown construction, did not yield any hydrocarbons As past results had been confounded, two separate laboratories were utilized 1 TOC elevations referenced for depth to water and assumed elevations below ground surface (bgs ) were adjusted to a common datum used by the Victor Fine Foods study The datum was assumed valid and applied to the study by Barber for direct correlation between studied elevations i 2 California Regional Water Quality Control Board Order No 5-01-057 2
