With all laboratory tests complete, the Salt Lake City-County Health Department said Wednesday a hazardous-waste spill at the site of a former Salt Lake City Fire Station poses no significant environmental danger.
A worker digging near a sump pump discovered the spill last November at 679 S. Second West, site of former Fire Station No. 12 and now the location of a used-car repair shop. Solvents from the pump leaked into the groundwater.Health department officials drilled three 15-foot-deep wells to take soil and water samples as well as to determine the extent of the contamination. The department recently completed laboratory tests on the samples.
"I don't see any danger with the site, said Garth Miner, water quality engineer for the health department. "We didn't find anything that would indicate any danger."
The largest concentration of chemicals found by the test wells is N-dibutyl Phthalate, a chemical used in plastics and detergents, Miner said. Samples taken from the site showed 34.8 micrograms of the chemical per liter of water, Miner said.
The chemical has not been standardized by the U.S. Environmental Protection Agency, but European governments have imposed a 200 microgram maximum for the chemical, he said.
Tests results from the site were given to Salt Lake City and then forwarded to the state Division of Solid and Hazardous Waste.
City Risk Management Director Jane Erickson said the city will wait for a response from the state to determine what measures must be taken to clean up the site.
The sump pump was supposed to carry effluent, including cleaning solvents and other materials, from the site into the city's sewer system. The pump, however, was not connected to the sewer when it was discovered by the worker, officials said.
