From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
A federal limit (an MCL or action level) is an enforceable legal cap; a health goal is often stricter. Meeting the limit is a compliance fact, not a health clearance, and PurityMap publishes no overall compliance verdict.
What you can do
Test first, then treat what was found
01 · TestTest your own tap
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
iSpring RCC7AK Alkaline Reverse Osmosis SystemiSpring · It treats only the water from its own faucet and sends part of the water to the drain; the NSF listing for the plain RCC7AK covers dissolved solids, not lead or PFAS.Use code REFISPRING at checkout: 10% off your first iSpring order.
iSpring RO5004F Tankless Reverse Osmosis System with UViSpring · Its PFAS and lead reduction claims are iSpring's own, with no third-party certification named for this model, and it treats only the water at its own faucet.Use code REFISPRING at checkout: 10% off your first iSpring order.
Waterdrop X12 Reverse Osmosis SystemWaterdrop · Its IAPMO NSF/ANSI 58 certification covers TDS reduction only, so its PFAS and lead claims rest on Waterdrop's own SGS lab testing.

WILLOWS WD (PWS ID CO0103100) is a public water system serving 19,000 people in Willows Wd, Colorado.
Where does WILLOWS WD get its water?
WILLOWS WD is on record as drawing from surface water. The source shapes which contaminants matter most for this system.
What does WILLOWS WD's monitoring record show?
PurityMap's record for WILLOWS WD holds 1 finding: 1 detected within the reference, from 1 evidence record. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.
Is WILLOWS WD's water safe to drink?
PurityMap does not issue a safety verdict. It publishes WILLOWS WD's measured results against each contaminant's benchmark so you can read them in context. Safety depends on the specific finding, your plumbing, and how the water reaches your tap.
How current is this WILLOWS WD data?
The latest published record for WILLOWS WD is dated 2026-10-15. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.
Does this assessment represent my home's tap water?
No. It is assessed at the water-system level from WILLOWS WD's own monitoring. It does not cover the service line to your building or the plumbing inside it, which can add lead and other metals after the water leaves the system. A tap test is the way to know what reaches your glass.
What contaminants were detected in WILLOWS WD?
Lead (90th percentile) was detected in this record. Each finding shows its measured value, its reference and its source on this page.
What should I do if I'm concerned about lead in WILLOWS WD's water?
Start with what the record shows: the lead findings above list each measured value against its reference. This record cannot show your home's plumbing, so a tap test tells you what reaches your glass. If you decide to treat your water, look for a filter whose certification covers the specific contaminant in your record; the section "Certified for a concern found here" lists only products with a current certification record for these concerns.
