What is tampering?
Tampering as defined in Regulation 11.2(1) is
- The introduction of a contaminant into a public water system or drinking water.
- To interfere with drinking water or the operation of a public water system.
One of the main aspects of tampering is that there is an intention of harming people or public water systems. Regulation 11 is also clear about what is not tampering. It states that tampering does not include the standard accepted treatment procedures performed by the supplier in preparing water for human consumption.
Tampering can occur along any one of the protected barriers of safe drinking water:
- Source water
- Treatment
- Storage
- Distribution

Why are there requirements to report tampering events?
The Colorado Department of Public Health and Environment is tasked with ensuring that drinking water is safe for human consumption throughout Colorado. Tampering presents an unacceptable risk to human health through potential contamination or other impairment of a drinking water system that could jeopardize its ability to provide safe water to the public. Once you inform the division of your tampering event, we will work with your system to determine next steps and connect you with state and federal partners to assist you in your recovery efforts.
Thank you for all you and your partners do to keep all Coloradans safe and healthy!
