FAQ - What if there is contact with sediment on shore and in water?

Colorado Department of Public Health and Environment stated, "Sediment is just one indicator of a healthy river. There is some level of contamination in most Colorado rivers because of past mining activities and the geology of the state," the agency added. "The Colorado Department of Public Health and Environment does not anticipate adverse health effects from exposure to contaminants detected in the water and sediment during typical recreational activities."

The San Juan Basin Heath Department concurs with the state health department findings, and advises that there are no adverse health effects from exposure to the water and sediment during normal recreational use (incidental or limited exposure). The San Juan Basin Health Department advises the public to avoid areas with orange sediment or discolored standing water. Further, anyone coming in contact with any orange sediment or discolored standing water should wash with soap and water after exposure.
