Compounds of Emerging Concern

Working Collaboratively to Monitor Untreated Drinking Water  

The Northern Colorado Compounds of Emerging Concern Program (CEC Program) is a collaborative effort initiated in 2009 to take a cost-effective and proactive approach to monitor the presence and concentration of pharmaceuticals, personal care products, hormones, pesticides and other compounds of concern in the C-BT and Windy Gap projects and other source waters of interest associated with drinking water supplies in Northern Colorado. 

Northern Water partners with the cities of Fort Collins, Boulder, Longmont, Loveland, Broomfield, Greeley and the Town of Estes Park, to share the annual program costs of approximately $150,000.

The objectives of this program are to:

• Monitor current conditions, trends and changes in water quality; 
• Assess water quality impacts from adverse events such as floods and wildfires;
• Collect data to support the assessment of regulatory issues;
• Maintain a high-quality water supply by providing a long-term, reliable dataset to support source water protection measures; and
• Maintain a robust and evolving list of compounds.

The program monitors contaminants from a variety of sources including municipal wastewater, industrial waste, runoff from lawns and agriculture, recreation and stormwater runoff. Monitoring is conducted biennially at more than 20 sampling locations. In years when regular monitoring is not conducted, funds are used to support special studies and program development.
