Page 6 of 6 <br />The soil-vapor samples will be transported under chain-of-custody procedures to a <br />CELAP-certified laboratory and analyzed for VOCs and IPA (tracer gas) in accordance <br />with EPA Method TO-15. <br />After collection of the sample, soil-vapor from the polyethylene tubing will be monitored <br />for the presence of volatile organics using an organic vapor meter equipped with a <br />photo-ionization detector (PID). <br />3.4. EQUIPMENT DECONTAMINATION <br />All non-disposable sampling equipment will be triple-rinsed in a solution of Alconox prior <br />to advancement of each boring. Rinseate generated during drilling activities will be <br />containerized in properly labeled Department of Transportation (DOT)-approved 55- <br />gallon drums and stored on-site in an area lacking public access. Disposal alternatives <br />will be evaluated at a later date based on laboratory results. <br />3.5. BORING ABANDONMENTS <br />Following borehole advancements, Portland cement (grout mix) will be utilized to <br />backfill each soil/groundwater sampling borehole utilizing a tremie pipe. The SJCEHD <br />will be given the opportunity to inspect the grout mix prior to backfilling activities.
