Coal Ash & Groundwater

 

March 13, 2018

Coal ash was exempt from waste handling laws in the United States until 2015. The rule established in 2015 had a number of requirements including one to check groundwater under coal ash sites.  The first round of groundwater data had to be made public by the utilities no later than March 2, 2018.

As of this writing, the Hoosier Environmental Council has not completed its evaluation of the new groundwater data for Indiana coal ash sites, but we have seen enough to confirm that where ever coal ash is stored without a liner under it, the groundwater beneath is contaminated.

The following are examples of contaminant levels in the data HEC has reviewed so far. For comparison, we have included a table of drinking water standards and health information for these chemicals.
