Book excerpt: 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).

This book was released on 1978 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nine dredged material land containment areas, located at upland, lowland, and island sites, were monitored during hydraulic dredging operations in fresh- and brackish-water riverine, lake, and estuarine environments. Influent-effluent sampling at the diked disposal areas showed that, with proper retention of suspended solids, most chemical constituents could be removed to near or below background water levels. Most heavy metals, oil and grease, chlorinated pesticides, and PCB's were almost totally associated with solids in both the influent and effluent samples. The only chemical parameters which failed to show average decreases of less than 90 percent in total effluent samples include: titanium (89 percent), manganese (88 percent), potassium (78 percent), magnesium (64 percent), ammonium nitrogen (57 percent), mercury (46 percent), op DDE (46 percent), and pp DDE (21 percent). Effluent mercury and titanium frequently appeared to be mainly associated with

This book was released on 1980 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to evaluate the impact of upland disposal of dredged material on groundwater quality. To this end, a baseline field study and sampling program was instituted at four case study sites: Grand Haven, Michigan; Sayreville, New Jersey; Houston, Texas; and Mobile, Alabama. Analyses of soil, disposed sediments, interstitial water, and groundwater were to provide information and data by which this impact could be quantified. Preliminary field testing was performed to characterize the hydrogeological system to define leachate pathways and possible controlling mechanisms from each site. Collection of groundwater samples consisted of two distinct sampling efforts. The initial study utilized 26 water samplers installed in or adjacent to each site, including 12 located within the dredged material, 10 offsite, and 4 directly below the site. Four field samplings were performed at approximately 3-month intervals. The second sampling effort relied upon six groundwater wells. The total number of samplings consisted of two at Pinto Island, four at Grand Haven, and five at Sayreville and Houston. Analyses of leachates from this sampling effort showed data comparable to the initial study. These data revealed the potential adverse water quality impact could exist. Degradation of groundwater resources within the proximity of the site would most probably be due to chloride, potassium, sodium, calcium, total organic carbon, alkalinity, iron, and manganese. Cadmium, copper, lead, mercury, nickel, zinc, and phosphorus concentrations were found to exist at levels that do not seem to pose water quality problems.

This book was released on 2013-09-11 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fate and Effects of Sediment-Bound Chemicals in Aquatic Systems presents the proceedings of the Sixth Pellston Workshop, held in Florissant, Colorado on August 12–17, 1984. This book presents the development of scientific inquiry of hazards to the aquatic environment. Organized into 27 chapters, this compilation of papers begins with an overview of water quality significance of sediment-associated contaminants to aquatic life. This text then addresses the topic of the role of suspended and settled sediments in regulating the effects of chemicals in the aquatic environment. Other chapters consider the nature and extent of partitioning and bioavailability, which are key elements in research efforts toward assessing the effects of sediments on water quality. This book discusses as well the regulatory and management strategies for chemicals entering public water supplies. The final chapter deals with conclusions and recommendations identified during the workshop. This book is a valuable resource for biologists and environmental scientists.

Available in PDF, EPUB and Kindle. Book excerpt: This document is intended to serve as a consistent "roadmap" for U.S. Army Corps of Engineers and U.S. Environmental Protection Agency personnel in evaluating the environmental acceptability of dredged amterial management alternatives. Specifically, its major objectives are to provide: A general technical framwork for evaluating the environmental acceptability of dredged material management, alternatives (open-water disposal, confined (diked) disposal, and beneficial uses). Additional technical guidance to augment present implementation and testing manuals for addressing the environmental acceptability of available management options for the discharge of dredged material in both ope water and confined sites. Enhanced consistency and coordination in USAC/EPA decision making in accordance with Federal environmantl statutes regulating dredged material management.
