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.

Long a center of the nation’s petrochemical industry, the Houston metro area has more than a dozen Superfund sites, designated by the Environmental Protection Agency as being among America’s most intensely contaminated places. Many are now flooded, with the risk that waters were stirring dangerous sediment.

The Highlands Acid Pit site near Chandler’s home was filled in the 1950s with toxic sludge and sulfuric acid from oil and gas operations. Though 22,000 cubic yards of hazardous waste and soil were excavated from the acid pits in the 1980s, the site is still considered a potential threat to groundwater, and the EPA maintains monitoring wells there.
