Analysis

What to know about Moffat's water

Moffat ranks #116 out of 246 cities in Colorado for water quality, placing it mid-range in the state.

Moffat relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.

As a small community water system, Moffat may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

The system has seen 8 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
