BRIGHTON CITY OF

BRIGHTON, CO · 56,304 people served · EPA PWSID CO0101025

The bottom line

BRIGHTON CITY OF (BRIGHTON, CO), which serves about 56,304 people, has recorded 1 health-based drinking-water contaminant in EPA violation records since 2016, most notably Total Trihalomethanes (TTHM). Its most recent lead 90th-percentile sample was 2.0 ppb, within the 15 ppb federal action level. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFPeA (0.0193 µg/L), PFOS (0.0106 µg/L), PFBA (0.0106 µg/L). PFOA/PFOS levels exceed the 2024 federal limit of 4 ppt (0.004 µg/L). A certified water filter can reduce these at the tap — see the certified options for each below.

What the testing found

Measured levels from EPA violation records, compared to the federal limit (MCL). The black line marks the legal limit.

Copper

1.77× the federal limit
Measured 2300 ppb · federal limit 1300 ppb · latest 12/31/1992 · 0 violations since 2016

Short-term: nausea/vomiting/cramps; long-term: liver/kidney damage. Leaches from copper plumbing, worse with corrosive water.

Total Trihalomethanes

1.2× the federal limit
Measured 0.0939 mg/L · federal limit 0.08 mg/L · latest 04/01/2023 · 1 violation since 2016

Chlorination byproduct; MCL 80 ug/L. Long-term bladder cancer and reproductive risk. Higher in surface-water systems.

Lead

Within federal limit
Measured 2 ppb · federal limit 15 ppb · latest 12/31/2023 · 0 violations since 2016

No safe level. Damages developing brain/nervous system in children; linked to lower IQ, kidney and cardiovascular harm in adults. Usually enters water from corroding pipes/solder, not the source.

Want certainty about your tap specifically (not just the system)? A certified mail-in lab test is the gold standard — system-wide records can differ from your home's plumbing. Some links above are affiliate links — see our disclosure.

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level. Your home's water can differ from the system average. Public domain data; we are not affiliated with the EPA.
