Those living in the Delaware town of Blades can now drink the water.
Officials recently installed carbon-filtration system that has nearly cleared up the PFC’s found in the underground water supply.
The Wilmington News Journal reports that authorities say residents should flush out their homes of any lingering contaminated water.
The town water now contains 3.4 parts per trillion of PFC’s which is a far lower concentration than what was found earlier this month.
The Environmental Protection Agency limits PFC’s to 70 parts per trillion.
