The City of Longmont is pleased to announce that the 2025 Water Quality Report is available online.

Inside the report, you will find information about Longmont’s drinking water and the results of the most recent tests done on our drinking water. The City of Longmont is proud to report that we met all applicable federal and state drinking water standards in 2025.

The City’s state-certified Water Quality laboratory performs most of the tests on your drinking water, and the rest are performed by contract laboratories. This ensures that the water delivered to your tap meets the standards set by the Environmental Protection Agency and the Colorado Department of Public Health and Environment. The City of Longmont takes pride in delivering safe, clean drinking water to every person in our community.

Printed copies of the Water Quality Report are available to view at the Longmont Public Library (409 Fourth Avenue), Utility Billing office (350 Kimbark Street), and the Development Services Center (385 Kimbark Street). If you are not able to view the report online or pick up a publicly available copy, please call 303-651-8416 for assistance.
