===Coal Ash Waste and Water Contamination===
In August 2010 a study released by the [[Environmental Integrity Project]], the [[Sierra Club]] and [[Earthjustice]] reported that Arkansas, along with 34 states, had significant groundwater contamination from coal ash that is not currently regulated by the Environmental Protection Agency (EPA). The report, in an attempt to pressure the EPA to regulate coal ash, noted that most states do not monitor drinking water contamination levels near waste disposal sites.<ref>[http://www.miamiherald.com/2010/08/26/1793995/study-of-coal-ash-sites-finds.html "Study of coal ash sites finds extensive water contamination"] Renee Schoff, ''Miami Herald'', August 26, 2010.</ref> The report mentioned Arkansas based [[Flint Creek Power Plant]] and the [[Independence Steam Station]] were two sites that have groundwater contamination due to coal ash waste.<ref>[http://www.businessweek.com/ap/financialnews/D9HRDN581.htm "Enviro groups: ND, SD coal ash polluting water"] Associated Press, August 24, 2010.</ref>
