Lodi City Landfill November 16,2011 <br /> • North of Awani Drive,Lodi,California Project No. 104690061 <br /> • Depending on metal analytical results, some samples may be additionally analyzed using the <br /> waste extraction test (WET) method or by the toxicity characteristic leaching procedure <br /> (TCLP)by EPA test method(s)6010/7471 A. <br /> • Due to the past agricultural uses in the area, select samples will be additionally analyzed for or- <br /> ganochlorine pesticides by EPA test method 8082A. <br /> • PCBs by EPA test method 8082. <br /> • Dioxins and furans by EPA test method 8290M. <br /> The analytical results will characterize the wastes, assist with developing a remedial action plan, <br /> if required, and depending on the planned remedial action, assist with evaluating off site disposal <br /> options. Two background samples will be analyzed for Title 22 metals (total metal concentra- <br /> tions)by EPA test methods 6010/7471A. The following table summarizes the proposed analytical <br /> testing program at this time based on drilling and sampling ten LFG wells and an assumed ten <br /> exploratory trenches.As previously indicated, it is likely the number of samples will be modified <br /> during the actual investigation. <br /> Table 2—Proposed Analytical Testing Program <br /> Constituents of Potential Concern EPA Test Method Estimated Number of <br /> Samples <br /> VOCs 8260B 20 <br /> Semi Volatile Organic Compounds SVOCs 8270C 20 <br /> Total Petroleum Hydrocarbons TPH extended range) 8015B 40 <br /> Title 22 metals TLC 601013/7471A* 30 <br /> Total lead TTLC 6010B 20 <br /> Polychlorinated Biphenyls CBs 8082 20 <br /> Organochlorine Pesticides 8081A 20 <br /> Dioxins/Furans see note below 8290M 1 <br /> Title 22 metals (STLC/TCLP),as required TBD TBD <br /> Notes: <br /> TTLC=Total Threshold Limit Concentration <br /> STLC=Solid Threshold Limit Concentration <br /> TBD=To be determined.The number of samples and actual metals to be analyzed for STLC and TCLP will be based on the TTLC <br /> concentration of a particular metal.Samples will be additionally analyzed if the metal concentration is equal to or exceeds 10 times <br /> the established STLC and is less than the established TTLC for that metal and/or if the TTLC concentration is equal to or 20 times the <br /> TCLP for that metal. <br /> TBD=to be determined <br /> Dioxins/Furan analysis only to be conducted if wastes were burned and on the sample containing the highest <br /> total lead concentration <br /> M <br /> 104690061 xsnW.doo 35 /�/Inya /�►oore <br />
