South Carolina Department of Health and Environmental Control was notified by CPW of the discharges.
Thursday's discharge resulted from a sewer system overflow at 8 a.m. when approximately 35,000 gallons overflowed at 635 Wade Hampton Boulevard (behind Office Depot) due to grease build-up, CPW reported.
Today, a second overflow occurred at 8:15 a.m. when about 10,000 gallons overflowed further downstream on the same line between Holly Circle and Woodland Drive, also due to grease build-up.
CPW, in a release, said it responded to the spill its cleanup activities were compete.
CPW said sewer system overflows can occur whenever a sewer collection line is damaged, becomes clogged, or surcharges due to heavy rains. Urban streams and rivers are especially susceptible due to their location near sewer collection systems. The presence of pollutants, especially fecal coliform, is always a potential in urban streams and rivers.
