(WBIR-Oak Ridge) Thousands of fish and salamanders were killed over the weekend, when a water line broke at Y-12 and spilled chlorinated water into East Fork Poplar Creek.
The rupture in the line, which provided drinking-quality water, was discoverd on Saturday. It sent an estimated 6,000,000 gallons of chlorinated water into the creek.
According to a press release, B&W Y-12 officials worked to get the pipe repaired, and to determine the impact on the creek. ORNL Biological Monitoring and Abatement Program personnel found an estimated 8,500 minnow-sized fish and almost 30 salamanders were killed in the area of the incoming chlorinated water.
By Sunday, no further aquatic life had been killed, and the workers noted "hundreds of healthy fish and other creek life were observed throughout the creek both days."
ORNL fishery biologists estimate the mid- to long-term impact on the resident fish and salamander populations associated with this event is likely to be minimal.
