The Environmental Protection Agency said Monday that it will hold a two-day summit in May to address a chemical that has been seen as a drinking water contaminant.

“EPA’s leadership summit will bring together stakeholders from across the country to build on the steps we are already taking and to identify immediate actions to protect public health,” EPA Administrator Scott Pruitt said in a statement. The summit will be held to address perfluoroalkyl and polyfluoroalkyl, which have been turning up in the water supplies of many states.
