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.

Frequently asked questions
Is Lake Monticello tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Lake Monticello, PFAS were detected below their limits, and PFPeA 6 ng/L with no federal or state limit. LAKE MONTICELLO (PWSID VA2065480) has a Purity Score of 100/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Lake Monticello?
LAKE MONTICELLO (PWS ID VA2065480) is the public water system on record for Lake Monticello, Virginia, serving about 12,943 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Lake Monticello get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Lake Monticello's water?
In EPA's UCMR 5 testing (2024-02-22 to 2024-11-18), PFBS was detected at 3.7 ng/L, below the 2,000 ng/L EPA health advisory and PFHxA was detected at 5.5 ng/L, below the 400,000 ng/L state limit. PFPeA (6 ng/L) was also detected; it has no federal or state limit.
Is there lead in Lake Monticello's tap water?
Lead is not in Lake Monticello's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
What does the latest Lake Monticello water report show?
PurityMap's current record for Lake Monticello holds 31 findings: 2 detected within the reference, 1 detected with no limit and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.

Every value is the published result from the cited public record. A reporting limit is the lowest level the method could reliably quantify; a non-detect is not a guarantee of zero.

Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where Lake Monticello reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at Lake Monticello: not detected (90th percentile, 2023–2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
