Lowcountry wells checked for coal contamination

Officials are investigating a possible coal contamination in residential water near the coast. Researchers at the College of Charleston say they are “fairly confident” the black particles found in six residential wells are fine grains of coal.
The Post and Courier of Charleston asked researchers to test the water in wells near a coal plant in Canadys. These tests done near the South Carolina Electric and Gas coal plant show that six wells so far have been affected. SCE&G is questioning the validity of these tests. Department of Health and Environmental Control officials say they are investigating the residential water. The report states that raw coal typically contains trace amounts of arsenic, cadmium, and other toxic heavy metals. Researchers are unclear if any of these particles are harmful to humans.
