A standardized system for procurement and testing of cores of lake bottom sediments for analysis of background and time-varying concentrations of potentially toxic materials, in particular mercury and lead, is required to allow correlation of data from various sampling sites. Core analysis includes description of structure, texture, color, and composition, measurement of pH and Eh, and determination of mercury and lead concentrations. A simple hand-operated coring device was developed and subsequently used to obtain such cores from Gravel Lake, WPAFB, Ohio. The cores obtained represent background levels for Gravel Lake and can be used as a baseline comparison for subsequent studies in the land management area at WPAFB and at other Air Force installations.
