Compliance record

Formal violations the EPA has on file for this supplier. A health-based violation means a contaminant limit or a required treatment was breached; the rest are monitoring or reporting failures — still violations, but not a measured health risk.

PFAS detected

PFAS are industrial “forever chemicals”. These are the EPA's latest nationwide test results (2023–2025).

Contaminant	Max	Detection rate	Period
PFBS	0.0037 µg/L	1/4	2024
Pfhxa	0.0055 µg/L	1/4	2024
Pfpea	0.0060 µg/L	1/4	2024

Other contaminants detected

Each bar shows the measured level as a share of the EPA limit: green is well under, amber is close to it, red is over. For lead and copper the limit applies to exactly the 90th-percentile figure shown, so red there means a real exceedance. For everything else the limit applies to a running annual average while the figure is the 95th percentile of this system's samples — over 100% is worth reading, but is not by itself a violation. Where a single sample came in higher than that percentile, it is noted under the bar. Formal violations are listed separately.

What contaminants were detected in Lake Monticello's water?

EPA monitoring detected TTHM, Total Haloacetic Acids (HAA5), Copper, Bromodichloromethane, Trichloroacetic Acid, and others. The full list with the level and data source for each is above.

How many people does Lake Monticello serve?

Lake Monticello reports serving 12,943 people in Virginia, per its EPA record.

Has Lake Monticello had any water quality violations?

The EPA has 4 violations on file for Lake Monticello, of which 4 are health-based (a contaminant limit or required treatment was breached) and 0 remain open. The rest are monitoring or reporting failures.

Where does this data come from?

Every figure is official EPA drinking-water monitoring — the Lead & Copper Rule, the UCMR-5 nationwide testing program, and the EPA Six-Year Review — not our own testing. Each number is labelled with its source and period.
