Physical and Chemical Characterization of Dredged Material Sediments and Leachates in Confined Land Disposal Areas.
Abstract
This field study was conducted to determine the water quality effect of the disposal of dredged material in confined upland areas. Four sites, Grand Haven, Michigan; Sayreville, New Jersey; Houston, Texas; and Pinto Island, Alabama, were chosen for this study. Each case study site was selected on the basis of distinct physical settings. Twenty-six sampling devices were installed at each site with 12 on-site, 10 off-site, and 4 beneath the site. Water samples were collected four times in nine months; soil and dredged material samples were collected during the first sampling visit. Analytical data show some significant increase in concentrations of chloride, potassium, sodium, calcium, magnesium, TOC, alkalinity, iron, and manganese in downgradient groundwaters. Concentrations of chlorinated hydrocarbons, cadmium, copper, mercury, lead, zinc, phosphate, and nickel were generally very low. Results obtained from this limited monitoring period have shown some degradation of groundwater quality due to the upland disposal of dredged material. Additional data are needed to formulate guidelines for the selection of disposal sites with minimal environmental impacts. (Author)
