Use EPA 40-m1 <br /> vials and amber bottles to obtain one water sample from each <br /> well after temperature, pH, and conductivity have stabilized. <br /> 15) Label and log water samples on a chain-of--custody form. <br /> 16) Transmit water samples to a state-certified laboratory for <br /> analysis of purgeable petroleum hydrocarbons (TPH-G) , aromatic <br /> hydrocarbons (BTEX) , fecal coliform, and total lead. <br /> 17) Contain purged water in 55 gallon DOT drums and store on-site <br /> pending analytical results. <br /> 18) Prepare a written report detailing the results of the work. <br />
