What is in the water at 45030
3 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
SOUTHWEST REGIONAL WATER DISTRICT
PWSID OH0903912 · OH · serves 42,856 people
PFAS and lithium
1 compound detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 1 sample.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| PFBS | 0.0031 µg/L | 1 | 10/30/2023 |
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 295 mg/L as CaCO₃, measured at 9 stations serving this system across 21 results, 2017-06-27 to 2020-11-10. Measured in the water source and distribution area, not at a tap, and not in your home.
HARRISON CITY PWS
PWSID OH3100812 · OH · serves 11,400 people · service area inferred by a model, not supplied by the state
PFAS and lithium
Sampled, nothing detected. Tested for 30 compounds under UCMR 5 with none found at or above its reporting limit. A reporting limit is the lowest concentration the method can measure, so this means “below that” rather than “zero”.
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
Too few readings to state a hardness. 3 station(s), 3 result(s). Below two stations and five results this page will not state a number: a median of two readings from one creek is not your water.
CINCINNATI PUBLIC WATER SYSTEM
PWSID OH3102612 · OH · serves 750,200 people
PFAS and lithium
3 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 6 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| PFOS | 0.0061 µg/L | 2 | 6/22/2023 |
| PFBA | 0.0052 µg/L | 2 | 6/22/2023 |
| PFBS | 0.0041 µg/L | 2 | 6/22/2023 |

Hardness
Median hardness 276 mg/L as CaCO₃, measured at 31 stations serving this system across 164 results, 2015-03-17 to 2024-12-17. 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.
