Scientists from the U.S. Geological Survey and the University of Colorado have found antidepressants, like Prozac, accumulating in the brains of fish near Boulder’s wastewater treatment plant, causing the reactions of the fish and their response to predators to slow down, according to the Denver Post: http://www.denverpost.com/ci_16037537.
Fish act as an early warning system for the presence of contaminants in water supplies. Studies have already documented the disruption to the reproductive systems of fish from contaminants finding their way into Colorado waterways.
In a recent article in The Durango Herald about personal care and pharmaceutical products in our water, Mike Meschke, environmental health director for the San Juan Basin Health Department, says, “Many of these compounds are not biodegradable and persist in our rivers and streams because they pass through treatment plants.” The chemicals may produce adverse developmental, reproductive, neurological and immune effects in humans and wildlife. “We’re rolling the dice,” according to Meschke, “We’re playing with an environmental cocktail in our water.”http://www.durangoherald.com/sections/Features/.
With concern growing over the potential danger to humans, wildlife and the environment, Colorado and federal authorities have ramped up efforts to test state rivers and reservoirs.
