SAMPLE HANDLING PROCEDURES <br /> i <br /> Ground-Water Sampling Methods <br /> A ground-water sample was collected from each monitoring well. Prior to sampling the well, <br /> approximately three to five well volumes were removed in order to bring fresh formation water <br /> into the well. The ground-water sample was collected using an individually wrapped disposable <br /> teflon bailer The ground-water sample was placed in the appropriate glass containers with <br /> teflon-lined lids. Each sample was labeled and immediately placed in an ice chest and cooled to <br /> 4°C using blue ice. <br /> Sample Shipment and Chain-of-Custody Procedures <br /> Complete records were kept on each sample including sampling date, sample type, location, and <br /> other pertinent information The sample containers were banded and sealed with chain-of-custody <br />. seals. The samples were cooled to 4°C at the site and maintained at that temperature until <br /> delivered to a State certified laboratory. <br /> Chain-of-custody procedures, generally described in Test Methods for Evaluating Solid Waste <br /> SW-846, U.S. EPA, Second Edition, were followed A chain-of-custody form accompanied the <br /> samples from the place of collection to the testing laboratory, and through the completion of the <br /> analytical process The chain-of-custody form included project identification information, the <br /> sample type and number, the date and time of sampling, the chemical analyses requested, and the <br /> identity of the person taking possession at each change of custody <br />
