Before sampling, each well will <br /> be purged by the removal of four or five casing volumes of water <br /> with a precleaned bailer. Purged water will be filtered through <br /> activated carbon and put into 55--gallnr drums. A sample of the <br /> filtered water will be taken for total petroleum hydrocarbon <br /> analysis. All drums will be stored in EA' s warehouse until <br /> k <br /> sample results are received and then disposed of appropriately. <br /> Ground-water samples will be collected with precleaned Teflon <br /> bailers . All water samples will be collected in appropriate <br /> containers with I Teflon-lined caps and preserved with either <br /> hydrochloric orisulfuric acid. All samples will be labeled, <br /> placcd on ice, and shipped under chall, ul custody to the state- <br /> certified laboratory.
