Data from Gold King Mine Response

The EPA surface water samples collected on August 16 and 17, 2015 from along the Animas River have been validated.  EPA has done a review of the data which included a comparison to screening levels for exposure during recreational use to determine if the metal concentrations are consistent with pre-incident levels.

Based on the results of the surface water samples in the Animas River, surface water concentrations are trending toward pre-event conditions.
