Environmental Laboratory

The Environmental Laboratory is located at Broomfield's Water Treatment Facility at 4395 W. 144th Ave. (north west of the intersection of 144th Ave. and Lowell Blvd).  The Lab's mission is to assess, protect and improve water quality in our community. Worker in Environmental LabThis mission is achieved by developing and maintaining a water quality laboratory program to ensure that all standards for the protection of public health and the environment are met.  The lab staff promptly responds to consumer concerns and provides timely follow-up. The staff works diligently  to ensure that the city and county water resources are appropriately used and protected.

Program Description  

Broomfield maintains an independent water quality laboratory to serve the community. Our laboratory meets stringent Quality Assurance requirements set forth by the Environmental Protection Agency (EPA) and the Colorado Department of Public Health and Environment (CDPHE), and is Certified to analyze drinking water for contaminants that may pose a health risk.

The Environmental Laboratory staff currently consists of 5 full-time and 1 part-time employee whose duties range from collecting samples, to chemical and microbiological analyses, to program management. The goals of the program are to:

  • Ensure compliance with all Drinking Water Standards for the protection of public health established by the EPA and CDPHE. Our water supply has never violated a drinking water standard or any other regulatory requirement. The annual Drinking Water Quality reported for 2007 is available here Broomfield's 2007 Consumer Confidence Report
  • Respond to consumer concerns by answering questions about drinking water, preparing and distributing water quality reports, collecting and analyzing samples, and investigating problems involving water quality, seeps, or other environmental concerns. Fact Sheets are available for frequently asked questions.
  • Analyze our source water supplies to help determine what treatment is needed to produce high-quality drinking water.
  • Monitor the treated water to assess the effectiveness of the treatment process.
  • Test new water mains to ensure that they meet sanitation requirements before they are connected to the distribution system.
  • Provide an early warning of problems in the distribution system that may require changes in the treatment process, or in the operation and maintenance of the system.
  • Support national and statewide efforts to implement a watershed approach to improving the quality of U.S. waters by actively participating in planning, monitoring and management activities for our watershed.

The Environmental Laboratory provides analytical and regulatory services to various customers, including Broomfield water consumers, the Drinking Water Treatment Facility, Wastewater Reclamation Facility, Industrial Pretreatment Program, the Engineering Inspection and Utilities Divisions, state and federal regulators, and stakeholders within the watershed. Environmental Laboratory services are independent of other City Divisions so that operational and regulatory functions may be carried out in an unbiased manner. 

      Environmental lab analysis

The Environmental Laboratory and Wastewater Laboratory work together to make the best use of resources and avoid unnecessary duplication of instrumentation or services. The Environmental Laboratory follows approved analytical methods and adheres to a Quality Assurance program designed to ensure that the data produced are accurate, reliable and defensible. The Laboratory is Certified by the Colorado Department of Public Health and Environment to perform Chemistry, Microbiology, and Radiochemistry to assess compliance with the federal Safe Drinking Water Act . Both manual and instrumental analysisEnvironmental lab worker methods are used, and instrumentation consists of an Autoanalyzer, Atomic Absorption Spectrometer, Gas Proportional Counter, and a Gas Chromatograph/Mass Spectrometer. Sampling locations include Broomfield’s raw water supplies, water treatment processes, drinking water, wastewater, residential tap water, and surface water leaving the Rocky Flats Environmental Technology Site. The laboratory also gathers water-quality information for various wells, streams, ditches, and ponds, and responds to residents with water-quality concerns.

In addition to analytical services, Environmental Laboratory personnel research and track the development of new regulations so that the City is prepared to meet upcoming requirements. Lab personnel participate in the regulatory process by evaluating the impact of changes to the water and wastewater regulations, preparing input, formal comments and testimony for the rulemaking process, and participating in State implementation of recently promulgated regulations.

Environmental Lab personnel also participate in various stakeholder groups, such as the Big Dry Creek Watershed Association and the Rocky Flats Integrated Monitoring Plan work group, and interface with other agencies as needed.
