EPA Doesn’t Expect Adverse Effects From Eldora Mine Leak

September 29, 2015

Environmental Protection Agency officials say they do not expect to see any adverse effects to drinking water in Boulder and Nederland after a mine near Eldora leaked 4,500 gallons of orange water into a creek last week.

The Boulder Daily Camera reports that the agency is continuing to investigate samples taken from the creek to see if the metal content in the water is higher than historic levels.

The orange water came from the Swathmore Mine on Sept. 21, temporarily turning the creek orange and leading officials to shut down water intake systems downstream.

EPA officials said the discharge from the mine was not toxic shortly after the spill and sent water samples for testing. They expect more results to be available later this week.
