Box 2009 <br /> Stockton,California 95201 <br /> RE: ANALYTICAL CHEMISTRY RESULTS FOR COMPOSPTE SOIL SAMPLES AT THE <br /> COCA-COLA ENTERPRISES - WEST FACILITY, 1100 NORTH WILSON WAY, <br /> STOCKTON,CALIFORNIA. JOS NO.90054.03. SITE CODE NO.1297. <br /> L'9ar Steve: <br /> r 4. At tN; written request of your office dated February 11, 1951 composite soil samples were <br /> 1 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 nnctive cyanide in the soil sample collected from the outside soil stockpile.. <br /> On March 7, 1991 a USTEC hydrogeclogist collected a total of six composite samples from the <br /> soil stockpile. All san;aies were collected and handled in accorciance with USTECs policy for <br /> the care and handling)f soil samples. In addition, chain-of-custody documentation was <br /> maintained and accomparded the samples to Sequoia Analytical Services in Redwood City, <br /> California. <br /> The analyrc al 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 /> r <br /> 1414 W. Br <br /> oadway Rd. • Ste.
