Request Water Quality Test Records - Denver

Utilities and Infrastructure Colorado 4 Minutes Read · published February 07, 2026 Flag of Colorado

In Denver, Colorado, residents and businesses can request water quality test records from the utility that supplies their water and from city offices that hold public records. This guide explains what records are typically available, how to submit a records request, typical timeframes, inspection and enforcement pathways, and practical steps to appeal or escalate requests. It covers requests to Denver Water (the regional water utility that serves most of Denver) and to City and County of Denver open-records processes where municipal records apply. Use the steps below to prepare a targeted request so agencies can locate test results, chain-of-custody logs, sampling locations, and corresponding analyses.

What records are available

Common water quality documents you can request include laboratory test reports, Consumer Confidence Reports (annual water quality reports), sampling logs, chain-of-custody forms, corrective action records, and correspondence related to specific samples or events. Records maintained vary by provider and by whether the sample is private, commercial, or system-supplied.

Check the utility’s published Consumer Confidence Report first; it often answers basic questions about contaminants and compliance.

How to request records

To request water quality test records for water supplied by Denver Water, submit a records request describing the document types, date ranges, and sample locations. Denver Water publishes annual Consumer Confidence Reports and maintains sample reports that may be available on request via its records process. Denver Water - Consumer Confidence Report[1]

  • Describe the records you need: sample ID, date, street address or meter ID, and laboratory name.
  • Specify a date range and preferred delivery format (PDF, CSV).
  • Include a contact name, phone and email for clarifying follow-up.
Be as specific as possible to reduce search time and fees.

If the records are held by City and County of Denver offices rather than the utility, use the City Clerk’s Open Records request process and include the same specificity. Requests to city offices follow Denver’s open-records rules and routing. City and County of Denver - Open Records Requests[2]

Penalties & Enforcement

Enforcement for drinking water violations affecting public water systems is carried out by the water provider in coordination with the Colorado Department of Public Health and Environment and the U.S. Environmental Protection Agency where federal rules apply. Specific civil fines, penalty amounts, or per-day schedules for municipal-level violations are not specified on the cited pages. [1]

  • Enforcer: primary enforcement lies with the water utility and state regulators; municipal code enforcement may apply to related local permits and reporting.
  • Inspection and complaint pathways: file complaints with Denver Water customer service or the City Clerk’s office for records disputes; state public health conducts compliance inspections for system violations.
  • Fines and escalation: specific fine amounts and escalation (first/repeat/continuing offences) are not specified on the cited pages.
  • Non-monetary sanctions: orders to correct, public notices, mandatory sampling, and court actions are typical remedies under state and federal rules.

Applications & Forms

Many record requests are handled by submitting a written open-records request; Denver Water and the City Clerk provide online submission portals or email contacts. If a specific form number exists it is listed on the agency’s records page; if no form is required, the agency accepts a written request specifying the records sought. [1]

Action steps

  • Identify whether Denver Water or a City office holds the records you need.
  • Prepare a written request with sample identifiers, dates, and preferred format.
  • Submit the request through the provider’s open-records portal or customer service channel and save proof of submission.
  • Track statutory response deadlines and follow up promptly if clarifications are requested.
Keep a copy of every correspondence and reference any request ID the agency issues.
