The State Environment: Toxic Chemicals Detected in S.C.’s Private Wells

In an alarming discovery, it has been reported that private wells across many parts of South Carolina are contaminated with toxic chemicals. These hazardous substances, often referred to as forever chemicals, or Per and Polyfluoroalkyl Substances (PFAS), are showing up most frequently in areas of Columbia and in regions south of Charlotte. A recent investigation has revealed that textile factories, such as Galey and Lord and other national manufacturers that have shipped chemicals to many places across South Carolina, are among the primary sources of these detrimental contaminants.

PFAS Levels and Concerns

The S.C. Department of Health and Environmental Control (DHEC) has stated that out of the 353 tested wells, only seven were found to have amounts of forever chemicals that exceed current federal safety levels. However, some amount of these toxins have been found in 155 different wells across the state. This is concerning because PFAS are known to have serious health implications. Any level of these substances in drinking water can potentially be hazardous to people if they are exposed over long periods. These toxins can increase risks of kidney and testicular cancer, thyroid disease, and result in immune system deficiencies.

Recognizing these risks, the U.S. Environmental Protection Agency (EPA) has proposed a strict new standard, as an initiative using their authority to protect individuals from these dangerous substances.

Finding the Source of Contamination

Locating the origin of contamination is a challenging task. PFAS pollution can come from various sources such as textile factories, wastewater treatment plants, and farms. Nonetheless, faced with the urgent need to address this situation, DHEC has committed to identifying the sources and taking appropriate actions to mitigate the situation.

Drinking Water Filter and Well Testing

DHEC is taking measures to tackle this problem. For owners of wells that are found to be polluted with PFAS, they are offering free filters to cleanse the water. Moreover, they have also committed to conducting free well tests to identify if wells are infected with forever chemicals.

Future Implications and Remedial Steps

The future implications of these findings are concerning. Although the EPA has not finalized the new standard of 4 parts per trillion, it marks a significant reduction from the current guidelines on PFAS levels in drinking water. These developments put pressure on the DHEC to step up its measures immediately. They are now actively encouraging residents to limit their consumption of certain types of fish as a preventive measure.

DHEC’s recent findings indicate that the spread of forever chemicals is not as widespread in groundwater wells as compared to rivers or to public drinking water systems. However, potential high-risk areas like Lexington County and Columbia are being closely watched. In addition, they have started initiatives to educate public on this issue and also offer free tests for those who are concerned about their wells being polluted.

As a state, South Carolina is still grappling with this major challenge. The hope is that with proper execution of the remedial measures and strict oversight, the problem can be mitigated.
