McArthur, OH – Following a nitrogen oxide gas release this week at the Austin Powder plant in Vinton County, local health officials are answering residents’ most pressing questions about safety, water quality and potential health impacts.
According to a joint statement from the Ohio Environmental Protection Agency (EPA) and the Vinton County Health Department, the chemical incident occurred Wednesday morning when an unknown substance entered a nitric acid tank, releasing nitrogen oxide gas into the air. No injuries were reported, and the air release has since stopped.
The Vinton County Health Department released a Frequently Asked Questions (FAQ) document Friday aimed at calming community concerns. According to the department, residential well water is currently considered safe for drinking, including for agricultural use. Officials say no contamination has been detected in surface waterways, and there are no restrictions on recreational water use at this time.
Residents are also advised there is no current threat to home gardens or crops. Swimming pools are not believed to be impacted, although those concerned can opt to drain and refill their pool water. Pet owners are encouraged to monitor animals for symptoms such as coughing or eye irritation and consult veterinarians with concerns.
The Ohio EPA continues to oversee testing of the site and surrounding areas, with drones deployed to monitor the air. So far, no positive nitrogen oxide readings have been reported from that monitoring. Further groundwater testing is planned by Austin Powder.
Emergency personnel, including the Zaleski Fire Department and county health officials, remain on standby as precautionary measures continue. The evacuation order for nearby Zaleski was lifted Wednesday afternoon.
