Coal Ash
Graphic of coal ash pond.
Coal ash is the hazardous waste that remains after coal is burned. Dumped into unlined ponds or mines, the toxins readily leach into drinking water supplies.

In Harm's Way: Coal Ash-Contaminated Sites

Coal-fired power plants generate about 140 million tons of fly ash, scrubber sludge, and other combustion wastes every year. These wastes contain some of the earth's most deadly pollutants, including toxic metals that can cause cancer and neurological harm in humans.

Coal combustion waste sites are known to have contaminated groundwater, wetlands, creeks, or rivers. These could easily have been prevented with sensible safeguards such as phasing out leak-prone ash ponds and requiring the use of synthetic liners and leachate collection systems. Yet, incredibly, ash and other coal combustion wastes are not subject to federal regulations that require these simple safeguards.

Use this interactive map to find where pond failures and water contamination have occurred:

Total known* cases of contamination and spills:
208 in 37 states
Updated: February 2014

* Note: These cases of documented water contamination are likely to be only a small percentage of the coal ash-contaminated sites in the U.S.
Most coal ash landfills and ponds do not conduct monitoring, so the majority of water contamination goes undetected. According to U.S. EPA, there are over 1,000 operating coal ash landfills and ponds and many hundreds of "retired" coal ash disposal sites.

Additional information on these contaminated sites: State Fact Sheets on Coal Ash.

For more information on coal ash ponds and landfills in the southeast, please visit Southeast Coal Ash Waste, a website managed by our coalition partners at the Southern Alliance for Clean Energy

A two-year study by the U.S. Fish and Wildlife Service in the early 1980s examined the effect of effluent discharges from a coal ash basin adjacent to Lake Erie and found elevated concentrations of trace elements identified as potentially harmful in sediments (arsenic, cobalt, possibly nickel, and selenium) and aquatic biota (arsenic, selenium, bromine, possibly cobalt, nickel, and chromium). The study concluded that chronic exposure to higher concentrations could undermine population fitness through increased susceptibility to disease, predation, and reduced reproductive capacity.

Map icon.Clinch River (AEP)
Cleveland, Virginia
In 1967, a dike from a coal ash pond at Clinch River Plant collapsed releasing a caustic ash slurry into the Clinch River. Some 217,000 fish were killed for up to 90 miles downriver and benthic macroinvertebrates, snails and mussels were also wiped out or very negatively affected. Forty years after the spill, aquatic ecosystems downstream remain degraded. High concentrations of copper and aluminum from power plant effluent also contribute to biotic impairment.

Glen Lyn, Virginia
Scientific studies in the 1970s and 1980s documented acute toxicity of effluent discharges from a fly ash holding pond to aquatic insects (mayflies) and bacteria in a mountain stream that flows into the New River. High TSS, pH at 9.5 units and cadmium and selenium exceeding Virginia Water Quality Standards for acute toxicity by 30 times and 4 times, respectively in the stream were responsible for the mortality. Bioaccumulation of copper by 580 times and cadmium and nickel by 10,000 times in duckweed, a floating plant in the pond, over levels in the water or sediments posed a toxic potential to off-site life if the plant was flushed from the pond.

Ecological studies in the late 1970s identified devastating impacts on aquatic life in a stream receiving discharge from ash ponds wiping out nearly all aquatic insects for 2.2 miles downstream. High conductivity and concentrations of cadmium and copper that likely exceeded federal and Wisconsin water quality criteria for acute toxicity in the stream as well as flocculent in the discharge coating the stream bottom were the culprits.

At Risk Populations: In August 2009, WE Energies informed nearby residents that their water was unsafe to drink and has been providing bottled water to about two dozen residences. There about 100 more households north of these homes and potentially in the pathway of contamination but most are on public water. Other homes are potentially effected by localized contamination further west.
