Notes:
A two-year ground-water monitoring program at three upland dredge disposal sites in the United States was conducted to determine whether the sites were contributing to ground-water degradation. Facilities were located at Grand Haven, Michigan, Sayreville, New Jersey, and Mobile, Alabama. Leachate samples were collected from vacuum/pressure lysimeters and ground-water wells. Ground-water wells were situated directly under the fill, downgradient, and in an area representative of indigeneous ground-water quality. Analyses of 27 parameters from 10 sampling periods indicated that calcium and manganese represent major water quality problems due to their contribution to water hardness. Of the trace metals, manganese and iron were found to exceed recommended EPA drinking-water quality standards at all sites. Levels of potassium, total organic carbon (TOC), chloride, sodium, calcium, alkalinity, and magnesium appear to affect local ground-water quality. Possible controlling mechanisms for observed leachate concentrations for these parameters include absorption, adsorption, ion exchange complexation, dilution and biological activity.
