Gold King Mine Data, September 17, 2015

Data from Gold King Mine Response

This data submission presents data for surface water and sediment samples collected on 8/24 and 8/25 from the Animas River. 

EPA has reviewed the data which includes comparison to screening levels for exposure during recreational use. The metal concentrations of the samples are below sediment/soil recreational screening levels, and are being maintained at pre-event conditions. Based on previous monitoring events it has been shown that metal concentrations may fluctuate from time to time because of water surges due to heavy rains or other events that may change the water flow rates or volume.


This data submission presents data for surface water and sediment samples collected on 9/10 from the San Juan River.


This data submission presents data for surface water samples collected on 8/21, 8/23-25, and 8/27-29; and, sediment samples collected on 8/21, and 8/23-28 from region 9.
