W-3Develop a Strategic Water Quality Improvement and Enforcement Plan for consecutive systems

Actions to assess water quality:

• The City develops an annual drinking water quality report and is consistently achieving compliance with Regulation 11 Colorado Primary Drinking Water Regulations. A copy of the 2024 drinking water quality report can be found below.
• Although it doesn’t impact the City of Longmont directly, House Bill HB23-1257, passed in 2024, establishes a CDPHE-administered water testing program for mobile home parks. This program requires the Colorado Department of Public Health and Environment (CDPHE) to test water quality in these parks. The City of Longmont is tracking and supporting, where possible, state efforts to improve water quality for our residents.  For more information, visit the CDPHE's Mobile Home Parks page.
• The City of Longmont actively protects the quality of public drinking water and consecutive systems through the Backflow Prevention and Cross-Connection Control Program.
• The City of Longmont actively protects the quality of public drinking water and consecutive systems through the Lead and Copper monitoring program and through compliance with the Lead and Copper Rule Improvements (Colorado Primary Drinking Water Regulations 5 CCR 1002-11 - 11.17). The City's treated drinking water continues to surpass both state and federal standards for Lead and Copper. In 2021, the EPA announced updates to drinking water regulations requiring water systems to investigate the materials of water service lines in their system and develop a comprehensive inventory. The City completed this water service line investigation in 2024, which resulted in a Non-Lead classification for all water service lines within City boundaries. The in-depth investigation of the City’s water lines included:
  • Reviewed all available historical records related to existing water lines
  • Verified pipe material for a representative number of service lines
  • Evaluated reliability of historical records review
  • Submitted findings to the Colorado Department of Public Health and Environment
