EPA. Methods identified in the Laboratory Data Shcct. <br />All the concentrations of the metal's analyzed are below the limits identified as hazardous by <br />Title 22. The portion of Title 22, the ZTT.0 values, identified by metal on the t; 1 Dana <br />column of that page, which identifies what are hazardous concentrations is found in Appendix <br />A. <br />The Laboratory Data Sheets, along with detection limits, and Chain of Custody documentation <br />are contained in Appendix B. <br />SUMMARY CONCLUSIONS AND RECOMMENDATIONS <br />The waste water in the 92 fifty five gallon drums identified and analyzed for CAM/CCR-17 <br />metals contained NO hazardous and/or toxic coneentrntions of those metals_ <br />The prior analysis and bioassay classified the waste water sample as neither hazardous or toxic_ <br />JPCA recommends the waste water in all 92 fifty five drums be disposed of as non- <br />hazardous and/or non toxic aqueous waste.
