Harvey's floodwaters are beginning to recede in Southwest Texas, but it's leaving people with a new problem: dirty water.
FOX's Tonya J. Powers has more:
Houston already had problems with sewer overflows after rainstorms, but now the city with 40 wastewater treatment plants faces an unprecedented challenge.
Several dozen sewer overflows have been reported in hurricane-affected areas, including Corpus Christi, complete with spilled fuel, waste runoffs, lawn pesticides and pollutants from the region's refineries and chemical plants.
The EPA says of the 2300 water systems contacted by federal regulators, a little more than 1500 are fully operational.
More than 160 systems have issued boil water notices and 50 have been shut down.
