Drinking water: Non-community groundwater inspections

The majority of public water systems in Colorado are classified as non-community groundwater (NCGW) systems. To assist with conducting sanitary surveys at NCGW systems, we've partnered with various local health departments throughout the stateLocal health departments participating in the program inspect under the following guidelines:
Response to the NCGW sanitary survey letter

About 30 days after the inspection, the local health department inspector or a department inspector will send you a letter detailing the sanitary survey findings. Regulation 11 states the public water system has:  

  • 45 days from the letter to respond in writing to any deficiencies/violations. 
  • 120 days from the letter to address any deficiencies/violations, unless we have approved the public water system’s corrective action plan.
