A warning advisory to stay out of the saltwater at Chambers Creek Regional Park in University Place was lifted Monday after test results showed water quality was normal, the Tacoma-Pierce County Health Department said.
Red “Closed” signs at the park’s beach off Grandview Avenue were removed Monday.
Pierce County officials on Friday had warned people to stay out of the waters off the park after 200,000 gallons of “partially disinfected” sewage accidentally were discharged into Puget Sound.
The discharge occurred Wednesday after a mechanical failure at the Chambers Creek Regional Wastewater Plant.
Independent testing of water samples collected Friday showed bacteria levels were below any risk to the public, said Cindy Callahan, an environmental health specialist with the department.
Carl Every, the county’s sewer division manager, said Friday the “effluent was fully treated, although a portion did not receive (ultraviolet) exposure during the disinfection stage due to a temporary system outage.”
“We immediately took samples and determined we did not exceed our discharge limits,” Every said.
