Well Inspection Program

The well inspection program was instituted for the protection of the groundwater resources and public health through enforcement of minimum well construction and pump installation standards. The program was created under Senate Bill 03-045. The objective of the program is to deal with the following concerns:  

  • Board of Examiners support
  • Complaint investigation
  • Education and outreach
  • Enforcement of the existing Colorado Revised Statutes and Rules and Regulations for Well Construction and Pump Installation
  • Monitoring/observation hole/well construction
  • Well and hole plugging and abandonment
  • Well construction and pump installation inspection

 

The Well Inspection Program currently has three inspectors including the Chief Well Inspector. Their contact information and locations they serve is available under Contact Us, Denver Office page, Well Inspection Section.
