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

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 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed analysis of contaminants in influents and effluents from two confined dredged material disposal areas is presented. The sites are located at Pinto Island, Mobile Bay, Alabama, and Grassy Island, Detroit, Michigan. The samples were separated into 0.05-micrometers, 0.45-micrometers, and 8.0-micrometers fractions. The total sample and filtrate were analyzed for metals, nutrients, total carbon, organic carbon, chlorinated hydrocarbons, oil and grease, sulfide, and solids content. The total solids were subjected to a geochemical partitioning scheme to determine changes of metal solid phases during confined area disposal. The oil and grease fractions in the samples were analyzed for trace metals. A 48-hour settling test was performed to quantify the migration of soil and grease and chlorinated hydrocarbons during resedimentation of dredged material within a confined area. A statistical analysis of the data was performed to determine the significance of variance in terms of pollutant loading between influent and background water; influent and effluent in terms of removal efficiency; and effluent and background water in terms of potential water quality impact. Tests for significance at the 95 and 99 percent confidence levels are presented. The results show that, in general, the removal efficiency of total trace metals was very similar to the total solids removal. These results are in agreement with the analytical data which show that approximately 99% of the total trace metals was associated with the solid settleable phase (> 8-micrometers).

Available in PDF, EPUB and Kindle. Book excerpt: This preface is being written at a time of exceptional public interest in the North Sea, following media head lines on toxic algal blooms, the mass mortality of common seals, and concern over pollution levels. These headlines may suggest that pollution of the North Sea is a recent event. This is not the case. Although no data are available (methods simply did not exist), it is safe to assume that emission (both into air and water) of heavy metals already started to increase in the 19th cen tury. The growth of cities and introduction of sewer sys tems led to the discharge of raw sewage and sewage sludge. The introduction of man-made (xenobiotic) organ ic chemicals and their subsequent emission into the North Sea commenced before the second world war. The shallower and coastal areas of the North Sea receive the highest concentrations of these pollutants. Not unexpectedly, these areas - some Norwegian fjords, the Dutch coast, the German Bight - show signs of ecosystem deterioration and eutrophication. A certain percentage of the pollutants does not remain in the North Sea but is "exported" to the Atlantic. The North Sea therefore con tributes to the global input of pollutants to the world's oceans. The major part of the pollutants accumulate in the North Sea and are incorporated in the bottom sediments. Although they are "out of sight", they should not be "out of mind".
