EL DORADO STREET, STOCKTON, CA <br /> SITE CODE 2080 <br /> Prepared for <br /> San Joaquin Public Health Service <br /> Environmental Health Division <br /> by <br /> Wm. J. Hunter & Associates <br /> March, 1995 <br /> In September, 1994, one ( 1 ) soil boring was placed in the <br /> approximate center of a previously removed waste oil on the <br /> Property to evaluate minor soil contamination encountered during <br /> prior investigative work conducted in 1993 The soil boring was <br /> Programmed to go to 40' to determine the vertical extent of heavy <br /> hydrocarbons detected by that earlier work. Soil contamination <br /> was encountered at 26' bgl, and was still present at 40' , the <br /> original programmed depth. Since this was below recorded .. <br /> groundwater depths during the past 10 years, it was decided to <br /> . continue drilling and convert the soil boring to a monitoring <br /> well. The well was completed on September 30 ; water samples <br /> taken on October 3, 1994 revealed significant levels of BTEX & <br /> TPH-G. The results of the laboratory analysis of those soil & <br /> water samples are summarized on Details of <br /> that work is covered in the WJH report titled "Interim Report & <br /> Results of Groundwater Investigation, " dated October 31 , 1994 <br /> The County EHD wrote to Mr. Valentine on February 27 , 1995, <br /> requiring that two (2) additional groundwater monitoring wells be <br /> placed on the property in order to obtain gradient data & <br /> evaluate the extent of the contamination encountered during the <br /> above work. A copy, of that letter is included as EXH_IB11-g. <br /> Their proposed locations are shown on PLATE IV This workplan is <br /> for the purpose of complying with that request. <br /> 2315 No El Dorado Avenue, Stockton, CA <br /> PROPERTY _,QWNE$_ <br /> Stephen Valentine, 6232 Hemet Ave. , Stockton, CA 95207 <br /> CONTACT PERSON: <br /> Steve Valentine, (209) 477-3471 <br /> 1 <br />
