Summary

No limits exceeded in the data EPA has, but the record is incomplete: no federal PFAS results and no lead results since 2002.

PFAS
Supplier testedNo PFAS results of its own in EPA's 2023–2025 testing. It buys water from Denver Water Board. In that testing, Denver Water Board had no PFAS detected. What reaches your tap depends on how much of that water this system uses and blends.
Lead
Out of dateEPA's national database has no lead results for this system since 2002 (then 9 ppb, 90th percentile). Systems this size normally test every one to three years, so this most likely means newer results were not reported to EPA, not that testing stopped. Ask the utility for its latest results.
Violations
None health-basedNo health-based violations since 2016.
What you can do

PFAS (“forever chemicals”)

No EPA results. No PFAS results of its own in EPA's 2023–2025 testing. It buys water from Denver Water Board. In that testing, Denver Water Board had no PFAS detected. What reaches your tap depends on how much of that water this system uses and blends. Your state may have its own PFAS sampling results.

Lead and copper

Latest 90th percentile: 9 ppb lead (Jan 2002 – Dec 2002). No results since 2002

This is the newest lead result in EPA's national database. Utilities report lead results to their state, and states pass them to EPA. Gaps like this usually mean the newer results did not reach EPA's database, not that the utility stopped testing. Results this old may not reflect the water today. Ask the utility or your state drinking water program for the latest lead monitoring.

Monitoring periodLead (90th pct.)
Jan 2002 – Dec 20029 ppb
Jan 2001 – Dec 20017 ppb
Jan 2000 – Dec 20008 ppb

Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.

Violations

No violations on record in EPA's Safe Drinking Water Information System.
