BE 1359 <br /> Holz Rubber Co.,Inc. <br /> Project Ash,Lodi,CA <br /> SAMPLE ANALYSIS AND ANALYTICAL METHODS <br /> In order to ultimately facilitate rapid transfer of the property, all groundwater samples will be analyzed on an <br /> expedited basis, by a California Certified environmental laboratory, for the full "TCL/TAL+30" analytical suite: <br /> target compound list (TCL) organics and 30 most prominent tentatively identified compounds (TICS) and target <br /> analyte list (TAL) metals. In addition, all groundwater samples will be analyzed for total petroleum hydrocarbons <br /> (TPHC)and pH. The groundwater analytical program is summarized in the following table: <br /> Ari ieaiParatnter <br /> Aw <br /> NOeatlsdaltodology <br /> TCL VOC+10 USEPA 624 <br /> TCL BNA+20 USEPA 625 <br /> TCL Pesticides/PCBs USEPA 608 <br /> TAL Metals/Cyanide USEPA 200.7 <br /> TPHC USEPA 418.1 <br /> H USEPA 150.1 <br /> Soil cuttings generated from the HydroPunch sampling system will be composited and analyzed as follows: <br /> Anal 'calfsarantetsFr Anal 'c8l Methadolb <br /> TCL VOC+10 USEPA 8240 <br /> TCL BNA+20 USEPA 8270 <br /> TCL Pesticides/PCBs USEPA 8080 <br /> TAL Metals/Cyanide USEPA 6010/7000 Series <br /> TPHC USEPA 418.1M <br /> H USEPA 9060 <br /> If elevated levels of total contaminants are found in the soil cuttings, they may be subjected to waste classification <br /> (toxicity characteristic leaching procedure [TCLP])analysis to determine proper disposal procedures. <br /> DECONTAMINATION PROCEDURE <br /> All equipment anticipated to contact soil or groundwater will be decontaminated prior to sampling and between <br /> each sampling event. Decontamination will consist of rinsing equipment in tap water to remove gross <br /> contamination followed by washing in distilled water with Alconoz, Liquinoz, or Citrinoz detergent followed <br /> by a distilled water rinse and air drying. Decontaminated sampling equipment will be placed on clean aluminum <br /> foil to air dry. Decontaminated sampling equipment will be wrapped in clean aluminum foil between sampling <br /> events. <br /> INVESTIGATION-DRIVEN WASTE HANDLING <br /> Soil cuttings will be placed in roll-off bins and left on site until the laboratory analytical results are received. Any <br /> soil that demonstrates visual contamination or evidence of contamination based on standard field screening <br /> techniques will be separated from clean cuttings. Laboratory analytical results will be used to characterize the <br /> cuttings and they will be subsequently disposed of in an applicable manner. <br /> Protective clothing, if any, and latex gloves used during investigation will be placed in plastic trash bags, and <br /> disposed as common refuse. Decontamination fluids will be containerized and retained on site until laboratory <br /> analytical results of soil sampling are received. If no contamination is identified in the soil samples, the <br /> decontamination fluids will be discharged to the city of Lodi sanitary sewer system. If contamination is identified, <br /> the decontamination fluids will be characterized and disposed appropriately. <br /> September 1996 2 <br /> g:lac&c-h&cV 3591 correspl20125cd.doc <br />
