On Thursday, the West Morgan-East Lawrence Water authority announced that Decatur chemical maker Daikin will pay $5 million to settle claims relating to drinking water from the Tennessee River that was fouled by high concentrations of the toxic chemicals PFOA and PFOS.

Almost 10 percent of that, $450,000, will go to reimbursing WMEL customers for water costs incurred when a “do not drink” warning was in effect in early summer.

The settlement, confirmed by both parties but subject to court approval, also includes $3.9 million for a granular activated carbon filtration system that will effectively remove the toxic chemicals “for the next three to four years,” according to a WMEL news release.
