OTTAWA, OH · 4,393 people served · EPA PWSID OH6900711
OTTAWA VILLAGE (OTTAWA, OH), which serves about 4,393 people, has recorded 3 health-based drinking-water contaminants in EPA violation records since 2016, most notably Copper, Total Trihalomethanes (TTHM), Lead. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFPeA (0.0904 µg/L), PFHxA (0.0518 µg/L), PFBA (0.0124 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
29.23× the federal limitShort-term: nausea/vomiting/cramps; long-term: liver/kidney damage. Leaches from copper plumbing, worse with corrosive water.
Total Trihalomethanes
1.1× the federal limitChlorination byproduct; MCL 80 ug/L. Long-term bladder cancer and reproductive risk. Higher in surface-water systems.
Lead
Not detectedNo 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.
PFAS "forever chemicals"
Detected by EPA's UCMR5 monitoring. The 2024 federal limit for PFOA and PFOS is 4 ppt (0.004 µg/L).

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.
