From the Bureau of Land Management via the The Chaffee County Times:
The Bureau of Land Management and Park County have discovered the presence of dioxane, an industrial chemical, within a closed municipal landfill and on surrounding public lands approximately one mile south of Fairplay.
According to the Colorado Department of Public Health and the Environment, the chemical exceeds regulatory limits but would not cause harmful health effects based on detected levels of exposure.
Currently, the dioxane has been detected only on public lands. The BLM and Park County will conduct additional monitoring efforts to determine the nature and extent of contamination.
The BLM leased 20 acres of public land to Park County in 1974 for use as a landfill under the Recreation and Public Purposes Act. Park County operated the landfill from the early 1970s to the early 1990s.
The BLM Royal Gorge Field Office has been working with Park County and CDPHE to bring the landfill into compliance.
As part of this effort, the BLM installed two groundwater monitoring wells earlier this year to evaluate water quality.
If you are concerned about your health, you can drink and cook with bottled water to limit your exposure. BLM is notifying adjacent landowners directly.
Local landowners can contact Sheila Cross, Park County, at 719-839-4272 or firstname.lastname@example.org to arrange groundwater testing or for more information on monitoring efforts.
