But for each shovelful thrown into the furnaces, a pile of ash was left in its place. Today, as coal’s dominance in the power sector wanes, those piles of ash have grown into mountains as coal ash became one of the largest waste streams in the country, according to the Environmental Protection Agency.Hundreds of waste ponds and landfills, many constructed without liners to prevent leaks, dot the American landscape, especially in the coal-rich Ohio Valley. And the ash they contain includes the concentrated remains of the many toxic compounds associated with coal and its combustion, such as arsenic, lead, and radium.The Ohio Valley ReSource and partner station WFPL analyzed newly available data from groundwater monitoring wells near ash disposal sites in the region and found that most show signs of leaking contaminants. At several sites, hazardous compounds are found in groundwater at levels that far exceed federal drinking water standards.What the first round of monitoring data revealed is a toxic blend of coal ash chemicals that appear to be leaching into groundwater across the country. Environmental advocates say the data demonstrate that contamination is ubiquitous, not just in the Ohio Valley but at coal ash sites around the United States.Earthjustice, a nonprofit environmental law center, found 92 percent of sites showed evidence of contamination in a review of 100 sites across the country. “And this is industry produced data,” Lisa Evans, an attorney with Earthjustice, emphasized. “Data is showing us that across the board there was groundwater contamination at almost every site in the country,” she said.In Kentucky and West Virginia, every power plant covered under the EPA rules had coal ash waste sites with evidence of contaminated groundwater, according to the analysis by WFPL and the Ohio Valley ReSource. Already, three sites in Ohio, four sites in West Virginia and 11 sites in Kentucky have said they will do more testing after finding evidence of possible groundwater contamination.More: Coal ash uncovered: New data reveal widespread contamination at Ohio Valley sites Industry data show widespread contamination from coal ashlast_img read more

first_imgBy Dialogo February 01, 2012 On January 30, Colombian President Juan Manuel Santos again rejected the proposals to collaborate in favor of peace talks with the country’s guerrilla groups that he has received from within Colombia and abroad, because they may be “counterproductive.” “Initiatives of all kinds have been presented, they send arguments, prominent national figures, international ones, they want to make a proposal, they want to create a group, they want to intervene,” Santos stated, without mentioning names, at an event in the department of Antioquia (in northwestern Colombia). The president said that his denial is the same one he communicated to several Latin American presidents who offered their collaboration during the founding summit of the Community of Latin American and Caribbean States (Celac) in Caracas, in December 2011. “The best thing at this point would be for them to stand by, to not meddle, to wait and see how we’ll move forward if tomorrow brings with it the appropriate circumstances, as we’ve said so many times,” Santos said. The National Liberation Army (ELN), Colombia’s second-largest guerrilla group, had asked the new Celac to hold conversations that could enable a peaceful solution to the armed conflict that has lasted almost half a century. Santos added on January 30 that it would be “inconvenient” to begin to create working groups and make public proposals for peace, “because it generates a negative and counterproductive atmosphere.” Since taking office in 2010, Santos has left the door open to dialogue with the ELN and Revolutionary Armed Forces of Colombia (FARC) guerrilla groups, on the condition that they demonstrate their readiness for peace through actions such as renouncing kidnapping, the recruitment of minors, and attacks.last_img read more
