A construction accident at the site of the new wastewater treatment plant in Thayer resulted in a minor sewage spill into the Warm Fork of the Spring River.
A sub-contractor hired by construction firm, Smith and Edwards, out of Mountain Grove, accidentally broke the 12-inch sewage main near the plant.
"We were able to shut off the flow pretty quickly," said Tim Hancock with Smith and Edwards. "We followed regulations and put up a containment dam to limit the contamination."
The Missouri Department of Natural Resources (DNR) investigated the spill and conducted testing both up and down stream from the contamination area. Test results show no harm was done to the waterway, and wells in the area were not affected.
The DNR considers discharges of wastewater from sanitary sewer collection systems to be threats to public health and the environment. The department's environmental emergency responders are called to the scene of more than 300 emergencies each year, including fires, traffic accidents, leaking storage tanks and other incidents that have the potential to have a negative environmental impact.
To report an environmental emergency, contact the 24-hour spill line at 573-634-2436. For more information about the DNR, visit the department's Web site at www.dnr.mo.gov.
