First, the surface release of coal ash with high levels of toxic elements and radioactivity to the environment has the potential to generate resuspended ambient fine particles containing these toxics into the atmosphere that may pose a health risk to local communities. Second, leaching of contaminants from the coal ash caused contamination of surface waters in areas of restricted water exchange, but only trace levels were found in the downstream Emory and Clinch Rivers due to river dilution. Third, the accumulation of Hg- and As-rich coal ash in river sediments has the potential to have an impact on the ecological system in the downstream rivers. environmental-health sediment-pollution coal-ash water-quality kingston-coal-ash-spill Mon, 02 May 2011 18:13:36 +0000 http://del.icio.us/url/aebff20ad51af3f3f40b9c7159dc6024#nbii_sain http://adsabs.harvard.edu/abs/2010AGUFM.H21A1023V http://del.icio.us/url/aebff20ad51af3f3f40b9c7159dc6024 http://feeds.del.icio.us/v2/rss/url/aebff20ad51af3f3f40b9c7159dc6024 nbii_sain's links An eighteen-month survey has revealed elevated levels of contaminants in surface water with restricted water exchange and in pore water extracted from the bottom sediments, downstream from the spill. Our research has shown that arsenic concentration in the pore water reached to 2,000 ppb due to the reducing conditions and the high mobility of the non-charged arsenic species. Generation of CCPs however is not restricted to a single accidental release, as over five hundred power plants nationwide generate approximately 130 million tons of CCPs each year, in which more than half is stored in 194 landfills and 161 holding ponds. In each of these sites effluents that are generated from leaching of CCPs could contain high levels of contaminants that could pose severe ecological hazards to the local aquatic systems. coal-ash water-resources water-pollution kingston-coal-ash-spill Mon, 13 Dec 2010 17:56:23 +0000 http://del.icio.us/url/4e310211953435ad8b22e7077f274f5f#nbii_sain http://www.tva.gov/kingston/presentations/setac2010/index.htm http://del.icio.us/url/4e310211953435ad8b22e7077f274f5f http://feeds.del.icio.us/v2/rss/url/4e310211953435ad8b22e7077f274f5f nbii_sain's links TVA organized a special platform session and a complementing poster session on the environmental investigations underway at the Kingston site for the annual meeting of the Society for Environmental Toxicology and Chemistry (SETAC) in Portland, OR in November 2010. environmental-monitoring kingston-coal-ash-spill tennessee Thu, 09 Dec 2010 15:01:34 +0000 http://del.icio.us/url/546e4c1f6fa4889454a64f12039c78e6#nbii_sain http://www.dukenews.duke.edu/2010/11/TVAstudy.html http://del.icio.us/url/546e4c1f6fa4889454a64f12039c78e6 http://feeds.del.icio.us/v2/rss/url/546e4c1f6fa4889454a64f12039c78e6 nbii_sain's links As the U.S. Environmental Protection Agency weighs whether to define coal ash as hazardous waste, a Duke University study identifies new monitoring protocols and insights that can help investigators more accurately measure and predict the ecological impacts of coal ash contaminants. “The take-away lesson is we need to change how and where we look for coal ash contaminants,” says Avner Vengosh, professor of geochemistry and water quality at Duke’s Nicholas School of the Environment. “Risks to water quality and aquatic life don’t end with surface water contamination, but much of our current monitoring does.” kingston-coal-ash-spill coal-ash accidents Thu, 09 Dec 2010 15:00:27 +0000 http://del.icio.us/url/9f46720b8e6b72a5525f43083d805525#nbii_sain http://pubs.acs.org/doi/abs/10.1021/es1026739 http://del.icio.us/url/9f46720b8e6b72a5525f43083d805525 http://feeds.del.icio.us/v2/rss/url/9f46720b8e6b72a5525f43083d805525 nbii_sain's links An 18 month investigation of the environmental impacts of the Tennessee Valley Authority (TVA) coal ash spill in Kingston, Tennessee combined with leaching experiments on the spilled TVA coal ash have revealed that leachable coal ash contaminants (LCACs), particularly arsenic, selenium, boron, strontium, and barium, have different effects on the quality of impacted environments. While LCACs levels in the downstream river water are relatively low and below the EPA drinking water and ecological thresholds, elevated levels were found in surface water with restricted water exchange and in pore water extracted from the river sediments downstream from the spill. The high concentration of arsenic (up to 2000 μg/L) is associated with some degree of anoxic conditions and predominance of the reduced arsenic species (arsenite) in the pore waters. kingston-coal-ash-spill coal accidents arsenic selenium boron strontium barium water-quality coal-ash Tennessee Thu, 28 Oct 2010 14:19:52 +0000 http://del.icio.us/url/349e4e1aed196b671ffad508e2966aab#nbii_sain http://www.environmentalintegrity.org/news_reports/documents/INHARMSWAY_FINAL3.pdf http://del.icio.us/url/349e4e1aed196b671ffad508e2966aab http://feeds.del.icio.us/v2/rss/url/349e4e1aed196b671ffad508e2966aab nbii_sain's links This report was a project of the Environmental Integrity Project with active support from Earthjustice and Sierra Club.

The effort is in response to a 22 December 2008 spill of 5.4 million cubic yards of wet coal ash when a dike broke at the Tennessee Valley Authority's Kingston Fossil Plant, in Tennessee. EPA has requested that electric utilities that have surface impoundments or similar structures, which the agency estimates could be as many as 300, provide information about their structural integrity. In addition, the agency will require remedial action at any facility found to pose a risk for potential failure. EPA is also developing regulations to address managing coal combustion residuals. “Environmental disasters like the one last December in Kingston should never happen anywhere in this country,” said EPA administrator Lisa P. Jackson.

First, the surface release of coal ash with high levels of toxic elements and radioactivity to the environment has the potential to generate resuspended ambient fine particles containing these toxics into the atmosphere that may pose a health risk to local communities. Second, leaching of contaminants from the coal ash caused contamination of surface waters in areas of restricted water exchange, but only trace levels were found in the downstream Emory and Clinch Rivers due to river dilution. Third, the accumulation of Hg- and As-rich coal ash in river sediments has the potential to have an impact on the ecological system in the downstream rivers by fish poisoning and methylmercury formation in anaerobic river sediments. kingston-coal-ash-spill coal-ash environmental-quality ecology fossil-fuels Research heavy-metals arsenic mercury methylmercury airborne-particles toxicants pollutants accidents environmental-chemistry water-supplies rivers sludge-disposal Sat, 12 Dec 2009 19:51:13 +0000 http://del.icio.us/url/135237dace398763ff96e8a5790add2a#nbii_sain http://www.appvoices.org/index.php?/site/av_news/tva_ash_spill_results/ http://del.icio.us/url/135237dace398763ff96e8a5790add2a http://feeds.del.icio.us/v2/rss/url/135237dace398763ff96e8a5790add2a nbii_sain's links Scientific study suggests the total recoverable toxic elements arsenic, barium, cadmium, lead, and selenium were at elevated levels below the ash spill; ash and ash-laden sediments from the fiver had arsenic levels that exceeded the EPA residential removal action limits; while selenium levels were increased dramatically downstream of the spill; fish body burdens of selenium were at and beyond the thresholds of toxicity for reproduction and growth; histological stuy of fish gills show a normal organization in the reference site fish. However, fish exposed to ash related toxic elements show several histological alterations indicative of toxic element stress. The preliminary data suggest the selenium in the fish tissues may be the result of legacy selenium.

The results indicate the ash contains small amounts of naturally occurring radioactive materials found in the earth and coal. Burning of the coal releases heat energy and reduces the amount of material in which the radioactive materials remain. Though this does not increase the amount of radioactive material present, its relative concentration is greater than it is in the earth and coal. Cesium-137 was also detected at low concentrations in some of the samples. Cesium- 137 from historical nuclear weapons programs and testing has been present in most terrestrial samples since 1970s.
