Barberton water hardness, 194 ppm and a wide swing

Barberton has genuinely hard water

For sample year 2024 Barberton reported average total hardness of 194 ppm, taken at the plant tap.

The USGS classifies water above 180 mg/L as very hard. Barberton’s average clears that line. This isn’t a marginal call or a matter of opinion — it’s the city’s own measurement placed against a federal classification.

Barberton is one of the harder public supplies in Summit County, and it is noticeably harder than Akron’s. Akron reported 107 mg/L for sample year 2025. On the annual averages that’s about 1.8 times.

Two things to be careful about with that comparison. The years are different: 194 ppm is Barberton’s 2024 figure, and 107 mg/L is Akron’s 2025 figure. At the time of writing Barberton hasn’t published a 2025 report. And it holds on the averages, not at every moment — Akron’s high end of 150 is above Barberton’s low end of 90.

The cities are close enough that Barberton maintains two emergency water connections to Akron. It purchased no Akron water in 2024.

The swing is the real story

The average is 194 ppm. The range is 90 to 288 ppm.

That’s a three-fold spread inside one year, and it changes what a good installation looks like. A softener set for 194 is set for a condition that is often not true. During the hard stretch it under-treats and you get the scale and the soap scum you bought the machine to avoid. During the soft stretch it over-regenerates, and you pay for salt and water you didn’t need.

This is the argument for metered regeneration rather than a timer. A metered valve regenerates on water actually used against the hardness actually present, so a supply that moves doesn’t leave the setting stranded. It’s also the argument for sizing off a real test rather than off the city average, because the average is the one number in the report that’s never what is in your pipe on a given day.

Converting to the unit your softener uses

Softeners are programmed in grains per gallon. Barberton publishes ppm only.

Dividing 194 by 17.1 gives roughly 11.3 grains per gallon. We want to be clear about what that sentence is: it’s arithmetic we did, using the standard conversion, not a figure the city published. Barberton’s report prints the ppm value and stops there. Akron’s report happens to print both units, which is why the Akron numbers on this site never need converting.

One more caution about the source document. Barberton’s report labels the row “Total Hardness (ppm)” and notes it as primarily calcium and magnesium content, without stating the calcium carbonate basis the USGS classification assumes. Reporting hardness as calcium carbonate is standard practice for these reports, and the figures behave as expected against Akron’s, which does state its basis. We’re telling you the document doesn’t print it because it doesn’t.

Where the water comes from

Barberton draws from the Upper Wolf Creek Watershed, about 18,062 acres across Medina and Summit Counties, feeding the Barberton Reservoir — 200 acres holding 670 million gallons, inside Summit County.

Three backup groundwater wells on Pigeon and Wolf Creek can supply 5.0 million gallons a day, held for drought or a reservoir algae bloom.

A surface reservoir is the sort of source whose chemistry moves with the weather, which is a plain explanation for a range as wide as 90 to 288. We’re offering that as the obvious reading rather than as something the city stated, because the report gives the numbers without explaining them.

What we would actually do here

Test the water at your tap, on the day. Size to what comes back rather than to 194. Use a metered valve so the machine tracks a supply that moves.

If your softener is already in and running on a timer, the setting is worth looking at before anything gets replaced. Barberton’s swing is wide enough that a timer is very likely wrong part of the year, and adjusting a control costs considerably less than a system.

The systems themselves are on water softeners and on whole-home systems. The measurement that decides between them is the free in-home test.
