Samples will be collected using <br /> disposable bailers; samples will be collected in 40-ml VOA vials. <br /> 16) Label and log water samples on a chain:-of-custody form. <br /> 17) Store the samples in a chilled container and tiransport under chain-of-custody procedure to <br /> a state-certified laboratory for analysis. Water samples will be analyzed .for 'rPH-g and <br /> BTE&X in accordance with E'PA methods 50.3018015 and 602, respectively. <br /> 19) Store purged water in 55-gallon 130T drums on-site pending analytical results. <br /> 4.2. RF-PORTING <br /> Upon completion of the investigaii(m, a report will be prepared. The report will summarize <br /> procedures and v411 include results of all laboratory analysis. The report gill be in a format <br /> acceptable to the P1SIEHD and the Central Valley regional Water Quality Control Board. The <br /> report will be reviewed and signets by a California registered Geologist. <br />
