Has Storm Helene Contaminated Private Wells in WNC?

As families recover from Storm Helene’s devastating effects, some fall ill due to what they suspect is contaminated well water. This issue is becoming increasingly urgent as water testing labs across Western North Carolina (WNC) confirm elevated levels of bacteria, parasites, cysts, and even worms in private wells post-storm. Our region’s underground aquifers have also been impacted, highlighting the importance of well water testing to prevent further illness.

Well Water Testing Recommendations

If your household relies on a private well in an area affected by Storm Helene, well water testing is strongly recommended, especially if the well was submerged during the storm or near flooded areas or other submerged wells.

What Type of Water Testing is Recommended?

Complete bacteria testing is essential, which should include:

  • E. Coli 
  • Coliform
  • Parasites/Cysts such as Giardia and Cryptosporidium (may require specialized testing)
  • Helminths/Worms (may require specialized testing)

Note: Standard water tests offered through county or state health departments may not cover specialized testing for parasites/cysts and helminths (worms).

In addition, as contaminants like nitrates and nitrites can settle deeper into the ground over time, it’s recommended to retest underground aquifers in flooded areas in 3 to 6 months, especially for shallow or dug wells.

Best Ways to Treat Contaminated Well Water

Professional chlorination remains the gold standard for disinfecting wells. A UV water filtration system is also a vital addition, especially for protecting against chlorine-resistant organisms.

  • Chlorination (disinfects the well)
  • UV water filter (sanitizes the water after it leaves the well)

Combining chlorination and UV filtration may provide the most comprehensive protection for many households.

Who Can Perform Chlorinations and Install UV Filters?

Professionals best handle these services:

  • Licensed well contractors
  • Plumbers
  • Water filtration companies

While some homeowners opt to chlorinate or “shock” their wells, professionals are best equipped to perform the task safely and effectively. If attempting it yourself, calculate the correct chlorine-to-water ratio (the approximate volume of water in the well must be known) and avoid using scented chlorine or products with additives.

How Long to Wait Before Using Water After Chlorination?

After chlorination, it can take several days to flush the chlorine out of the system, especially for deep or low-yield wells. During this time, the water will not be safe to drink or use for washing. Many households choose to leave for the weekend during the chlorination process. If this isn’t feasible, consider installing a UV filter first and scheduling the chlorination for a more convenient time.

Summary

In the aftermath of Storm Helene, many private wells in WNC may be contaminated with harmful bacteria, parasites, and other pathogens. Well water testing is highly recommended, especially for homes in flooded areas or with submerged wells. Complete bacteria testing, including specialized tests for parasites and helminths, is critical to ensure water safety.

Conclusion

To prevent illness and protect your family’s health, testing your well water and addressing any contamination is essential. Professional chlorination and UV water filtration systems offer the best protection. If you’re unsure where to start, contact licensed well contractors, plumbers, or water filtration companies who can help safeguard your water supply.
