Abstract

Wetlands are known to be efficient filters of metals dissolved in ground and surface waters. This paper presents the results of geochemical reconnaissance sampling done at the request of the U.S. Environmental Protection Agency in wetlands in Vassar Meadow, Eagle County, Colorado. Ten wetlands were sampled and found to be variously enriched in chromium, molybdenum, and uranium. The uranium and chromium concentrations (and, to a lesser extent, molybdenum) represent an environmental concern should they be released as a result of anthropogenic disturbance. The metal accumulation in these wetlands documents that the wetlands have been functioning as filters that protect water quality in East Brush Creek by lowering the dissolved metal content in water.
