Box 2009 <br /> Stockton,California 95201 <br /> RE: ANALYTICAL CHEMISTRY RESULTS FOR COMPOSITE SOIL SAMPLES AT THE <br /> COCA-COLA ENTERPRISES - WEST FACILITY, 1100 NORTH WILSON WAY, <br /> STOCKTON,CALIFORNIA. JOB NO. 90054.03. SITE CODE NO. 1297. <br /> Dear Steve: <br /> At the written request of your office dated February 11, 1991 composite soil samples were <br /> collected from the aerating soils at the Stockton facility. The samples were analyzed for reactive <br /> cyanide in order to verify the analytical results of previous sampling which indicated elevated <br /> amounts of reactive cyanide in the soil sample collected from the outside soil stockpile.. <br /> On]March 7, `'-91 a USTEC hydrogeologist collected a total of six composite samples from the <br /> w_ soil stockpile. All samples were collected and handled in accordance with USTEC's policy for <br /> _ the care and handling of soil samples. In addition, chain-of-custody documentation was <br /> maintained and accompanied the samples to Sequoia Analytical Services in Redwood City, <br /> Califor-sia. <br /> The analytical chemistry results indicate a reactive cyanide concentration of 1.7 ppm in <br /> - composite sample number 5,and not detected in the remaining soils samples. The laboratory <br /> noted on the certificate of analysis that no gas evolved from the sample when tested with water. <br /> It is our understanding that the State of California toxicologist has informed you that 1.7 ppm <br /> of reactive cyanide in one sample poses no significant problem and does not require further <br /> action. In addition,USTEC understands that no additional samples for reactive cyanide will be <br /> required for the Stockton facility. <br /> i <br /> 6 <br /> � e <br /> 1 � <br /> 1 ; <br /> Rar 1.414 W, i3roadway Rd. • SIC. 150 • Tt"Mpe.
