Includes bibliographical references (pages 23-24). "Sediments are one of the main repositories of contaminants in the environment; After the sediment is deposited, changes in the redox conditions can alter the availability and mobility of the contaminants. Sediment pore water, referred also as interstitial water, is the linking agent between the bottom sediments and the overlying water. The technique involved in the collection of sediment pore water plays a crucial role in studies of pore water quality. The in situ pore water sampler ("peeper") developed by Hesslein (1976), and its modifications have been used in many sediment pore water investigations. However, the "peeper" technique is complex and susceptible to contamination. This report provides a simple and complete "manual of instructions" in the use of the peepers, such as cleaning, assembly, retrieval, and preservation"--Abstract. gccst Sediments gccst Water quality gccst Methodology Azcue, José M., 1957- author.
