• completion of Chain-of-Custody records; and • sample shipment. B-1.6 Sampling Personnel Sampling will be conducted by personnel trained in the this surface water sampling procedure. Sampling personnel will have thoroughly reviewed this procedure prior to each sampling event. B-1.7 Arrangements with Analytical Laboratory Prior to sampling, arrangements will be made with the analytical laboratory that will conduct the sample analyses to make the necessary arrangements for the analyses and to obtain the appropriate sample containers, preservatives, and shipping containers. The laboratory will provide a sufficient number of sample containers for the surface-water locations to be sampled and the QC samples to be included. The laboratory will determine the proper type and size for the containers, based upon the analyses to be conducted. For samples requiring chemical preservation, preservatives will be added to containers by [he laboratory prior [o shipping containers [o the facility. Shipping containers, ice chests with adequate container padding and cooling media, will be sent to the facility with the containers. B-1.8 Preparation for Sampling Equipment will be controlled, cleaned, and maintained in accordance equipment decontamination procedures specified in Section 1.3 of this procedure. B-1.9 Sample Collection The surface water samples will be collected in a manner to prevent contamination of the surface-water being sampled and the samples themselves. The primary way such contamination can occur is through contact with improperly cleaned equipment. To prevent such contamination, sampling equipment and sample containers will be thoroughly cleaned before and after field use and between uses at different sampling locations as described in the equipment decontamination procedures (Section L.3), in addition to the use of properly cleaned equipment, two further precautions will be followed. • A clean pair of new, disposable latex (or similar) gloves will be wom at each different location. • Field personnel will minimize [he potential for cross-contamination that could be caused by trace constituents the might occur on [heir waders or rubber boots by using along- handled sampling cup or bailer to collect the sample away from the area disturbed by wading. The following paragraphs present procedures for the activities which comprise surface-water sample acquisition. These activities will be performed in the same order as presented below. Exceptions to this procedure will be noted in the permanent sampling record.
