EWG's drinking water quality report shows
results of tests conducted by the water utility and provided to the Environmental Working Group by the South Carolina Department of Health & Environmental Control, as well as
information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2021 - March 2021), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
Nitrate, a fertilizer chemical, frequently contaminates drinking water due to agricultural and urban runoff, and discharges from municipal wastewater treatment plants and septic tanks. Excessive nitrate in water can cause oxygen deprivation in infants and increase the risk of cancer. Click here to read more about nitrate.
Nitrate was found at 5.1 times above EWG's Health Guideline.
EWG Health Guideline
0.14 ppm or less
The state and national averages were calculated using the averages of the contaminant measurements for each utility in 2017-2019. ppm = parts per million
The EWG Health Guideline of 0.14 ppm for nitrate was defined by EWG . This health guideline protects against cancer and harm to fetal growth and development.
Radium is a radioactive element that causes bone cancer and other cancers. It can occur naturally in groundwater, and oil and gas extraction activities such as hydraulic fracturing can elevate concentrations.
Radium, combined (-226 & -228) was found at 21 times above EWG's Health Guideline.
EWG Health Guideline
0.05 pCi/L or less
The state and national averages were calculated using the averages of the contaminant measurements for each utility in 2014-2019. pCi/L = picocuries per liter
EWG applied the health guideline of 0.05 pCi/L, defined by the California Office of Environmental Health Hazard Assessment as a public health goal for radium-226, to radium-226 and radium-228 combined. This health guideline protects against cancer.
Includes chemicals detected in 2017-2019 for which annual utility averages exceeded an EWG-selected health guideline established by a federal or state public health authority; radiological contaminants detected between 2014 and 2019.
Other Contaminants Tested
Chemicals tested for but not detected from 2014 to 2019:
One of the best ways to push for cleaner water is to hold accountable the elected officials who have a say in water quality – from city hall and the state legislature to Congress all the way to the Oval Office – by asking questions and demanding answers.
