Four Alabama environmental organizations have released new interactive maps highlighting groundwater pollution reported by Alabama Power and Power South at coal ash pits throughout the state. Alabama Power’s federally required monitoring shows significant pollution of groundwater with arsenic, radium, and more. Pollution has persisted even after Alabama Power closed their leaking Gadsden pit using cap-in-place - the same method it plans for millions of tons of coal ash in their pits statewide.
The data from the map shows that between 28.8 million - 42.6 million gallons of sewage overflows were reported in 2016, not including the 9% of spills reported that did not include a volume estimate. However, the true number of spills that actually occurred is far higher than the map indicates as there were many spills that were reported with incomplete data or not reported at all.
