3 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
DEL-CO WATER COMPANY, INC.
PWSID OH2101412 · OH · serves 150,000 people
PFAS and lithium
6 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 19 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 13 µg/L | 2 | 7/11/2023 |
| PFBA | 0.011 µg/L | 4 | 7/11/2023 |
| PFHxA | 0.0087 µg/L | 4 | 7/11/2023 |
| PFPeA | 0.0063 µg/L | 4 | 7/11/2023 |
| PFBS | 0.0043 µg/L | 4 | 7/11/2023 |
| PFOA | 0.0042 µg/L | 1 | 7/11/2023 |
A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.
Health-based violations
No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
Median hardness 271 mg/L as CaCO₃, measured at 59 stations serving this system across 596 results, 2015-04-16 to 2024-12-12. Measured in the water source and distribution area, not at a tap, and not in your home.
BEXLEY CITY PWS
PWSID OH2500103 · OH · serves 14,250 people · service area inferred by a model, not supplied by the state

| PFPeA | 0.011 µg/L | 3 | 8/25/2023 |

It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.

Median hardness 240 mg/L as CaCO₃, measured at 23 stations serving this system across 136 results, 2015-02-12 to 2024-12-12. Measured in the water source and distribution area, not at a tap, and not in your home.
What this report cannot tell you
Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
