c <br /> A-B1 <br /> APPENDIX B <br /> SAMPLE COLLECTION PROCEDURES <br /> AND ANALYTICAL SCANS <br /> During this investigation, soil samples were collected as follows: <br /> 1. Pre-washed 8 ounce wide-mouth glass jars having screw-on bakelite lids with <br /> Teflon liners were obtained from the laboratory which would perform the <br /> analyses. <br /> 2. The sample collection site was cleaned of surface debris. <br /> 3. Samples from 0-6" depth were collected with a' stainless steel trowel . <br /> Composite samples were prepared by mixing four to six individual samples in <br /> a stainless steel bucket and transferring a portion to a sample jar. <br /> 4. Samples from 18"-24" were collected by augering a 6" diameter hole to 18" <br /> and sampling with a 2" auger. Cores from the 2" auger were placed directly <br /> into a sample jar and the laboratory instructed to homogonize the sample <br /> prior to analyses. At some sites, a composite of two samples from 18"-24" <br /> was prepared. <br /> 5. Between samples the trowels, bucket, augers, and other sampling equipment, <br /> including protective boots and gloves, were washed with ammonia and water <br /> and rinsed with acetone. <br /> s <br /> Water samples were collected as follows: <br /> 1. Pre-washed 1 liter amber glass bottles with screw-on caps having Teflon <br /> liners were obtained from the laboratory. Two bottles were filled at each <br /> sample site. <br /> 2. Surface water samples were collected by submerging the sample bottle and <br /> capping underwater or by transferring from a disposable plastic collection <br /> bottle held with a stainless steel handle. <br /> 3. Well water samples were collected from a faucet as close to the well as <br /> possible (preferably before any pressure tank) and after running the well <br /> for several minutes . Well water was discharged directly into the sample <br /> bottles. <br /> 4. Between samples, the handles and protective gloves were washed with anrionia <br /> and water and rinsed with acetone. <br /> Samples collected were transported in an ice chest and submitted to the labo- <br /> ratory as soon as possible. If overnight storage was necessary, samples were <br /> placed in a refrigerator. At sites where analyses showed p�_,sticidies in a sell , <br /> a resampling was conducted for confirmation of the positive results. r--� <br /> � PH � , �_�..-1� i <br />
