More than 4,000 fish and crayfish were killed by chlorinated water and mercury at the Y-12 National Security Complex in two series of incidents in 2018 and 2021.

The first series of incidents was likely caused by the release of mercury while crews were cleaning up and removing equipment at the Alpha-4 Building on the west side of Y-12, according to scientists and officials. Alpha-4 is the most contaminated of the four major mercury-contaminated buildings at Y-12. Millions of pounds of mercury were used at Y-12 decades ago to produce nuclear weapons parts. Removing mercury-contaminated buildings, equipment, and soil remains one of the top challenges of cleaning up the Oak Ridge Reservation.

Fish caught in Melton Hill Reservoir could break state record

A fish caught in Melton Hill Reservoir on Thursday could break a state record, wildlife officials said. The muskellunge, better known as a musky, was hauled in by angler Stephen Paul in the Knox County portion of Melton Hill Reservoir on Thursday evening, the Tennessee Wildlife Resources Agency said. The giant musky weighed 43 pounds and 14 ounces. It bit Paul’s artificial lure around 6 p.m. Thursday and provided him with the “catch of a lifetime,” the TWRA said. The fish could break a 34-year-old state record. The TWRA said muskellunge are a challenging fish to catch, particularly when they get older and wiser. Paul’s friend Dylan Gano was with him to document the historic catch. [Read more…]

One of the most destructive forces in the ocean today is a fish. One of the most misunderstood fish in the ocean is known for its destructive force.

The lionfish and the shark will be the topics of the next episode of “Classroom Under the Sea,” an online lecture series hosted by two educators living underwater for 73 days.

The live program start at 1 p.m. Eastern on Thursday, October 23. Viewers can watch at roanestate.edu/classroomunderthesea and on youtube.com/classroomunderthesea.

Biology professor Bruce Cantrell and adjunct professor Jessica Fain from Roane State Community College in East Tennessee are living and working in an underwater habitat—Jules’ Undersea Lodge on Key Largo in the Florida Keys—for 73 days. While in the habitat, Fain and Cantrell are hosting “Classroom Under the Sea,” presented by Roane State and the Marine Resources Development Foundation on Key Largo. [Read more…]

‘Diligent’ engineer discovers Y-12 water line break that spilled six million gallons

East Fork Poplar Creek starts at a spring at the Y-12 National Security Complex and flows through Oak Ridge. About six million gallons of water spilled into it in early June, killing several thousand small fish, after a 10-inch water line ruptured at Y-12.

The break in a 10-inch water pipe at the Y-12 National Security Complex on a Friday night in June—it spilled about six million gallons of water and killed several thousand small fish—was discovered by a diligent engineer who had returned to the plant to check on an abnormal water tower report, officials said.

The Defense Nuclear Facilities Safety Board reported that the plant contractor’s utilities and environmental compliance organizations both had had indications of an abnormal condition, but B&W Y-12 had not established a procedure to respond to the signals.

“The break was discovered because a diligent system engineer decided to come back in to the site and check on an anomalous report of a low level in a water tower that had cleared as the pumps refilled the tank,” the DNFSB report said. “B&W management is evaluating ways to improve recognition of a problem from the available indications during off hours.” [Read more…]

Milky white water, half-dozen dead minnows, but no hazardous materials found

The water was milky white and there were a half-dozen dead minnows on Thursday evening, but the Oak Ridge Fire Department was unable to find any hazardous materials in a small creek that flows through Alvin K. Bissell Park in the center of the city.

“We couldn’t detect what it actually was, and we couldn’t find any place that it was introduced into the stream,” ORFD Chief Darryl Kerley said Friday.

Kerley said medium and larger fish in the area were okay and so was a snapping turtle. [Read more…]

TVA finishes excavating spilled coal ash at Kingston plant, starts covering disposal area

Ash that spilled into the brown embayment pictured above has been removed, and workers are placing a black liner over an ash containment cell, pictured at center, preparing to close it late next year. More than 5.4 million cubic yards of coal ash spilled in December 2008 when a storage cell used by the Kingston Fossil Plant, back left, failed.

KINGSTON—It was the largest ash spill in U.S. history. A dike failed on a storage cell on a cold December night more than four years ago, and roughly 5.4 million cubic yards of coal ash surged out, covering about 300 acres of land and water near the Kingston Fossil Plant.

No one was injured, but 40 homes in the area were affected. The ash filled three embayments north of the coal-fired plant, covered Swan Pond Road, and flowed into the Emory River. Three homes became uninhabitable because of structural damage.

The work to clean up the gray sludge, which had been four to six feet deep, has been under way since the Dec. 22, 2008, spill. On Friday, officials paused to celebrate two milestones in the six-year, $1.2 billion project. [Read more…]

Water line rupture at Y-12 kills small fish, salamanders

East Fork Poplar Creek starts at a spring at the Y-12 National Security Complex and flows through Oak Ridge. It has been listed on a state list of impaired waterways due to mercury and polychlorinated biphenyls, among other things.

About six million gallons of chlorinated water spilled into East Fork Poplar Creek from a ruptured drinking water line at the Y-12 National Security Complex, and an estimated 8,500 minnow-sized fish and almost 30 salamanders were killed in the area of the incoming chlorinated water, a media advisory said.

It said the rupture in the potable water line was found Saturday. The numbers of dead fish and salamanders were determined by workers from the Oak Ridge National Laboratory Biological Monitoring and Abatement Program. [Read more…]
