Watershed Summit Illuminates Issues and Risk of Emerging Contaminants

Dr. Larry Barber of the USGS and Dr. Alan Vajda of CU Denver delivered challenging and troubling presentations (The Boulder Creek Watershed Natural Laboratory and Landscape Endocrinology) on the presence of emerging contaminants in the Boulder Creek and other watersheds at the Boulder Waterkeeper Watershed Forum. Biologic and pharmaceutical chemicals that may not have been fully understood when the Clean Water Act was passed in 1972 are emerging as significant issues of concern for human and aquatic life. The number of new chemicals and the range of impacts are just now being researched. Boulder Creek is a leading site for investigations and analysis.
