The distribution of naturally occurring radionuclides in ground water of the Kirkwood- Cohansey aquifer system in southern New Jersey was assessed during The Kirkwood-Cohansey aquifer system consists of quartz-sand formations overlain by a feldspar-rich quartz-sand formation, the Bridgeton Formation, that is heavily developed agriculturally. The NJ Department of Environmental Protection currently reviews all requests for allocations of water from the Kirkwood-Cohansey aquifer and other fresh water sources. The thresholds the Department applies have proven inadequate to protect the aquifer from the cumulative and individual impacts of withdrawals on surface waters.

Groundwater is essential for water supply and plays a critical role in maintaining the environmental health of freshwater and estuarine ecosystems in the Atlantic Coastal basins of New Jersey. The unconfined Kirkwood-Cohansey aquifer system and the confined Atlantic City foot sand are major sources of groundwater in the area, and each faces.   Mercury, notoriously toxic in an organic compound known as methyl mercury, has been found in the aquifer in an inorganic form that is much less dangerous. Last fall, the department ordered nine.

Mercury pollution in the Kirkwood-Cohansey Aquifer by United States Download PDF EPUB FB2

Mercury mobilization from aquifer sediments inoculated with mercury was investigated by leaching the sed - iments with two concentrations of nitric acid (a component of acid rain), a sodium chloride solu- tion (simulating road salt), and three fertilizer solu- tions.

Mercury pollution in the Kirkwood-Cohansey Aquifer: oversight hearing before the Subcommittee on Energy and the Environment of the Committee on Interior and Insular Affairs, House of Representatives, One Hundred Second Congress, second session hearing held in Trenton, New Jersey, Septem Possible Sources of Inorganic Mercury in the New Jersey Coastal Plain.

It was concluded early in the investigations of Hg in the New Jersey Coastal Plain that a natural (geologic) source of Hg was unlikely (Dooley, ); however, no chemical analy- ses of aquifer sediments were available, only mineralogical by: 4. Anomalously high Hg concentrations have been detected from domestic wells in the Kirkwood-Cohansey Aquifer System, New Jersey Coastal Plain.

Mercury concentrations ranging from [mu]g/l in relatively shallow wells ([lt] feet) have been detected. Mercury pollution in the Kirkwood-Cohansey Aquifer book Concentrations in excess of [mu]g/l.

Relation of mercury to other chemical constituents in ground water in the Kirkwood-Cohansey aquifer system, New Jersey Coastal Plain, and mechanisms for mobilization of mercury from sediments to ground by: Anomalously high Hg concentrations have been detected from domestic wells in the Kirkwood-Cohansey Aquifer System, New Jersey Coastal Plain.

Mercury concentrations ranging from [mu]g/l in relatively shallow wells ([lt] feet) have been detected. The Kirkwood-Cohansey aquifer contains trillion gallons of water, enough to cover New Jersey in 10 ft ( m) of water, and enough to cover half of the United States water supply in a year.

The waters support the Pine Barrens y: Sand, silt, clay. The Kirkwood-Cohansey water-table aquifer is present throughout nearly the entire New Jersey Coastal Plain. The aquifer covers approximately square miles (fig. It is thickest and most productive in the central and southern part of its extent.

Description of the Aquifer The Kirkwood-Cohansey water-table aquifer is made up. It is a shallow, unconfined or “water table” aquifer meaning that the water in the ground is just below the land’s surface in most areas. Most water in wetlands, lakes, streams, and rivers in southern New Jersey is water that seeps or flows directly from the ground from the Kirkwood-Cohansey aquifer.

Mobilization of mercury from land surface to groundwater and biogeochemical transformations along flow paths in an unconsolidated sandy, acidic aquifer. The Kirkwood-Cohansey aquifer supplies virtually all the water in the streams, rivers, ponds and wetlands of southern New Jersey.

It also provides more than 45 billion gallons of water each year to over a million residents, visitors, farms and other businesses. air pollution to release mercury into the aquifer. Such a process may explain why as much as 10% or more of wells in the Kirkwood-Cohansey aquifer are testing positive for dangerously high levels of mercury.

The long-term environmental effects of contamination such as radium and mercury have yet to be studied.

Draining of surface waters and. To accurately model mercury transport to water bodies, an assessment of this pollutant's behavior in the watershed is critical. Partition coefficients, defined as an estimate of the ratio of the pollutant concentration sorbed onto soil/sediment particles to the pollutant concentration dissolved in pore water at equilibrium, is an important term in multimedia by: Standards for mercury in water, and other regulations.

For drinking water the World Health Organization (WHO) guideline for THg is 1, ng/L, a level (in some instances given as mg/L or µg/L) adopted by the European Union countries, the United Kingdom, Canada, and India (WHO, ; NIEA, ; Environment Canada, ; Srivastava, ).Cited by:   Increases in industrial mercury (Hg) emissions in recent years have led many researchers to believe that Hg from the atmosphere constitutes a main source of Hg to aquatic biota in the absence of point source discharges.

Pollution on land or just below surface can readily contaminate groundwater, especially in water table aquifers with porous soils, as in the Kirkwood-Cohansey Aquifer.

A water table aquifer, or an unconfined aquifer is an aquifer whose water reaches up to the water table with no confining layer above it. The wells draw water from the areally extensive ( km2) unconfined Kirkwood-Cohansey aquifer system, in which background concentrations of Hg are about μg/L or less.

Addresses all aspects of pollution and the global impact on the environment; contains numerous entries and essays using the most current scientific data to. A healthy Kirkwood-Cohansey aquifer provides water of sufficient quantity and quality to meet the needs of both humans and the unique ecological systems it sustains for the present and future.

Introduction. Mercury (Hg) is a highly toxic element and its contamination of groundwater is a significant environmental problem (Barringer et al.,Lamborg et al., ).In the United Sates, elevated mercury levels have been reported in many aquifer systems, including groundwater wells in Kentucky (Davidson and Fisher, ), New Jersey's Kirkwood-Cohansey aquifer Cited by: 9.New Jersey Public LawChapter directed the Pinelands Commission to assess and prepare a report on the key hydrologic and ecological information needed to determine how the current and future water-supply needs within the Pinelands area may be met while protecting the Kirkwood-Cohansey aquifer system and avoiding any adverse ecological impact on the .
