The short answer

1 result is above the health goal. The worst: Arsenic, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: copper at 128 mg/L (2004) is left out of this report: it is one of the results Ohio sent EPA in 2006, all at µg/L magnitudes though EPA’s file marks them mg/L.

Arsenic, total trihalomethanes (TTHM), fluoride, chromium (total), haloacetic acids (HAA5) and nitrate: Ohio’s own results, samples taken from April 15, 2020 to Oct. 6, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

10.1ppb

Highest yearly average, 2020 to 2025

2025: not found

Averaged by year, the highest was 10.1 ppb, in 2020, which EPA rounds to 10 ppb to compare: at its legal limit of 10 ppb, not above it. Its highest single sample was 12 ppb. In 2025, the latest year on file, it wasn’t found in any of its four samples. EPA recorded no violation for arsenic at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.6 ppb, in 2012.

10.3ppb

Highest yearly average, 2020 to 2025

2025, one sample: 8.7 ppb

Averaged by year, the highest was 10.3 ppb, in 2024, below EPA’s legal limit of 80 ppb. In 2025, the latest year on file, its one sample was 8.7 ppb.

Below EPA’s limits

0.3ppm

Highest yearly average, 2020 to 2024

2024, one sample: 0.27 ppm

Averaged by year, the highest was 0.3 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2024, the latest year on file, its one sample was 0.27 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.34 ppm, in 2012.

What handles it

4 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)
  • Haloacetic acids (HAA5)
  • Lead
  • Nitrate

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

Hardness

Very hard, 248 mg/L (14.5 grains per gallon), at its one sampling point, in 2020.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

Violations since 2016

No health-based violations on file with EPA since 2016. There is 1 monitoring or reporting violation: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Arsenic, total trihalomethanes (TTHM), fluoride, chromium (total), haloacetic acids (HAA5) and nitrate results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Granger Lake Condo 4 PWS’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Ohio’s results run from April 15, 2020 to Oct. 6, 2025.

Testing your own tap

Granger Lake Condo 4 PWS’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Ohio certifies.

No lab Ohio certifies is within 75 miles of the area Granger Lake Condo 4 PWS serves on the state’s list. Some take samples by mail; the state’s page lists them all.
