Water Quality

Providing safe drinking water to the Dorchester County Water and Sewer Department’s utility customers of the Ashley Phosphate, Southern Palms, ArborGen, I-95 Wilco and Edisto Tribal Council water systems is our highest priority.

Regulated by the South Carolina Department of Health and Environmental Control (SC DHEC), we follow strict standards to ensure that the water remains safe. Many safeguards are in place and regular monitoring occurs as required.

The Department furnishes an Annual Drinking Water Quality Report to all customers in these water service areas. SC DHEC also requires Dorchester County to supply customers with regulated detects that are the responsibility of the Department which is included with the annual water quality reports.
