WASHINGTON (AP) — The Environmental Protection Agency says an unknown amount of a dangerous chemical linked to birth defects and cancer may have washed downriver from a Houston-area Superfund site during the flooding from Hurricane Harvey.

PASADENA, Texas (AP) — The U.S. government received reports of three spills at one of Houston's dirtiest Superfund toxic waste sites in the days after the drenching rains from Hurricane Harvey finally stopped. Aerial photos reviewed by The Associated Press show dark-colored water surrounding the site as the floods receded, flowing through Vince Bayou and into the city's ship channel.

HIGHLANDS, Texas (AP) — As Dwight Chandler sipped beer and swept out the thick muck caked inside his devastated home, he worried whether Harvey's floodwaters had also washed in pollution from the old acid pit just a couple blocks away.
