Animas River Open To Public, Recreation After Contamination
DURANGO, Colo. (CBS4)- The Animas River has reopened to the public for recreational use after the wastewater contamination from an abandoned mine last week.
The La Plata County sheriff reopened the river at noon on Friday. Sheriff Sean Smith said his decision to reopen the river was made after he looked at the analysis of sediment from the Colorado Department of Public Health and Environment.
An EPA-supervised crew accidentally unleashed 3 million gallons of wastewater from an old mine that flowed into the Animas River on Aug. 5.
The health department said the data show levels of contamination below what would be a concern for human health during typical recreational exposure.

"My primary concern is the public health and safety of our community. In an abundance of caution, with the consultation of all our partner agencies, I issued the order to close the river to recreational uses on Thursday, August 6. With the release of preliminary results from the state health department and its accompanying recommendation, I am opening our river for recreation effective Friday, August 14, 2015 at noon with the health advisory," said Smith.
According to the health department, "Sediment is just one indicator of a healthy river, and there is some level of contamination in most Colorado rivers because of past mining activities and the geology of the state. 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 Agency for Toxic Substances and Disease Registry recommends the following recommendations are prudent public health practices regarding contact with sediments and surface water:
- Don't drink untreated water from the river
- Wash hands thoroughly with soap and water after contact with the sediment and surface water.
- Avoid contact in areas where there is visible discoloration in sediment or river water.
- Wash clothes after contact with sediments and surface water.
The EPA says the sediment samples collected in the Animas River from Baker's Bridge to north of Durango have been analyzed but not yet validated. The EPA has conducted a preliminary review of the data which included a comparison to background to determine if the metal concentrations are consistent with pre-incident levels.
The Gold King Mine is one of 200 mines in the state that has site water quality issues. The millions of gallons of contaminated water that came out of the mine all at once would have come out anyway but usually over several weeks, according to the head of Colorado's Inactive Mine Reclamation Program.
The agency said metal results that exceeded pre-incident levels were subsequently compared to risk-based screening levels. These preliminary results indicate that minor exceedances of background concentrations were observed for antimony, lead, silver, thallium. However, comparison to risk-based screening values found those to be below risk screening levels.
While the Animas River has been reopened to recreational use, irrigation ditches that draw from the river continue to be flushed. Agricultural users are encouraged to exercise patience until the process is complete.
La Plata County has flushed and allowed use of some irrigation ditches for watering crops such as wheat and alfalfa. The county said they are working to reopen all ditches.
Operators of ditches that use water from the Animas River are asked to call the La Plata County Call Center at 970-385-8700 so officials can coordinate reopening of all river head gates. Flushing may cause local, temporary discoloration of the Animas River, which should clear quickly.
Gardeners who use water from the Animas River and grow leafy vegetables and root crops should call the CSU Extension office at 970-382-6463. Answers to questions are site and crop specific.
The Colorado Department of Agriculture State Veterinarian's Office is confident that water from the Animas River can be used to water livestock.
"The information we have received shows that water quality levels are comparable to those prior to the spill," said Dr. Carl Heckendorf, State Veterinarian for the Colorado Department of Agriculture. "We will continue to monitor the situation and will provide updates if it becomes necessary."
Local, tribal, state and federal agencies will continue to test water and sediment routinely and will respond quickly to any potential issues.
