Hypothesis
Wells can be colonized by Naegleria fowleri and may be an unrecognized source of this organism that could present a human health risk.
Conclusion
The study found that Naegleria fowleri DNA was detected in 11 of 143 wells, indicating that groundwater may be a previously unrecognized health threat.
Supporting Evidence
- N. fowleri was detected in 11 of 143 wells sampled.
- 30 out of 185 total samples tested positive for N. fowleri.
- The organism was more often detected after wells were purged.
Takeaway
This study shows that a dangerous germ called Naegleria fowleri can live in well water, which might make people sick.
Methodology
Water samples were collected from drinking water wells and tested for Naegleria fowleri using PCR analysis.
Limitations
The study did not determine if the detected amebas were infectious.
