Source Water Assessment Report
The Colorado Department of Public Health and Environment (CDPHE) has completed a source water assessment for the Town of Johnstown 
as required by the 1996 Safe Drinking Water Act amendments and in accordance with Colorado’s Source Water Assessment and Protection (SWAP) program. The purpose of this assessment is to analyze the potential susceptibility of each public drinking water source to contamination, and to supply pertinent information so that decision-makers voluntarily can develop and implement appropriate preventive measures to protect these water sources. The Safe Drinking Water Act requires that the public water system and its consumers be informed of the assessment results.
Please note: The Consumer Confidence Report is amended to include the correct state defined potential sources of contamination. No contaminents have been detected. If any contaminants were detected in our water their sources may be from: chemical storage, wastewater discharge,mine sites, leaking storage tanks, oil/gas wells, roads, transportation, residential, farming, forests, and other facilities.
