KNOXVILLE, Tenn. (WOKI / WVLT) — Cleanup efforts following a fiery train derailment in Morgan County are entering a new phase, with officials now closely monitoring ethanol contamination in the surrounding environment.
The derailment, which happened in a remote area near Lancing, initially sparked multiple rail cars on fire. Crews later confirmed some of those cars were carrying ethanol, prompting a multi-agency response that continues days later.
🆕 What’s New
Officials say the focus has now shifted from emergency response to ongoing environmental monitoring, including testing air and water quality for traces of ethanol.
- The Tennessee Department of Environment and Conservation (TDEC) has issued a temporary contact advisory for parts of the Emory River
- Rock Creek Campground remains closed as a precaution
- Agencies including EPA and TEMA are continuing coordinated testing
Despite those precautions, officials report that current air and water quality readings are considered safe.
🔥 What Happened
According to 911 recordings, a Norfolk Southern representative first reported the derailment, describing rail cars off the track along a river and some cars on fire.
Emergency crews initially faced challenges accessing the remote location. As they approached, responders determined the incident involved hazardous materials — specifically ethanol.
⚠️ Understanding the Risks
Experts say ethanol, while commonly used in fuels and even food products, can pose environmental and health risks in large quantities.
Nathan Duncan, a chemistry professor at Maryville College, explained that ethanol can absorb water and pull moisture from living things, potentially damaging plants and ecosystems.
He also warned of short-term health effects.
- Fumes can irritate the lungs
- Exposure may cause inflammation
- Strong odors are often noticeable
“You don’t want to breathe a lot of alcohol either,” Duncan said, noting the vapors can be irritating.
🌱 Environmental Impact
The good news: experts say ethanol tends to break down naturally over time.
- Bacteria in waterways will consume the ethanol
- Environmental impacts are expected to be temporary
- Some grass, trees, and organisms may be affected in the short term
Full recovery could take weeks to months, depending on conditions.
🚧 What’s Next
Crews will continue:
- Monitoring air and water conditions
- Managing cleanup in the derailment zone
- Maintaining safety closures and advisories
Officials are urging the public to avoid restricted areas and follow river advisories until cleanup is complete.
