5 Colo. Code Regs. § 1005-1.1
The rules and regulations establish the minimum standards for environmental laboratories wishing certification to test samples under the Colorado Primary Drinking Water Regulations, and federal Safe Drinking Water Act (SDWA). Certification of laboratories is granted independently for each of the following testing areas: chemistry, microbiology, and radiochemistry. Under the Colorado Revised Statutes, Section 25-1.5-101(e), laboratory approval and certification is delegated to the Department.
Through the rules and regulations, the Department affords laboratories certification for state requirements, federal requirements and interstate recognition (reciprocity) by adopting the SDWA standards in their entirety. The rules and regulations provide for reliable, accurate, and comparable laboratory data for public and environmental health monitoring and safety decisions.
