DEQ: Pharmaceuticals from Big Sky spill unlikely to pose human health risk
“A state report on pharmaceutical levels in the nearly 30 million gallons of treated wastewater that spilled into the Gallatin River last month said that risks to human health are unlikely but had no certainty about impacts to aquatic life.
The Montana Department of Environmental Quality tested for 46 different chemicals in the water ranging from antibiotics to caffeine and found 18 of them in the water spilling directly from a Yellowstone Club wastewater pond and 11 of the chemicals in the Gallatin’s tributaries. Chemicals found in the water ranged from penicillin to caffeine to a drug used for pigs. . . . “
“. . . . The chemical found most frequently was the antibiotic sulfamethoxazole. It was found at all of the sampling sites, which included at the spill and seven other spots on either tributaries of the Gallatin or the main river. It was the only chemical found downstream of the confluence of the West Fork and the main Gallatin River.
The antibiotic carbadox was also found in the water at low levels. The drug is used for pigs, and earlier this month the U.S. Food and Drug Administration moved toward taking the drug off the market. . . . “
