Cuyahoga Falls reports less hardness than it did in 2022

The number in the report has moved

Cuyahoga Falls states a finished hardness range in its annual water quality report. Reading four of them in a row, the stated range has come down:

• 2022 report — 160 to 180 ppm
• 2023 report — 140 to 180 ppm
• 2024 report — 120 to 140 ppm
• 2025 report — 100 to 130 ppm

That’s the city’s own line, in the city’s own documents, four years running.

We’re going to be careful about what that means, because it would be easy to oversell. None of those reports states a reason. No policy change is announced, no decision is described, no cause is given. The documents show the stated range changing and nothing more.

There’s a hint in the reports themselves as to why it might move without anyone deciding anything. The plant softens roughly two-thirds of the iron filter effluent by ion exchange and blends it back with the unsoftened remainder, and the report qualifies that share with “depending on the raw water hardness.” A blend ratio that responds to incoming water will produce a finished number that drifts. Whether what you’re seeing across four reports is an operational drift or a deliberate change, we can’t tell you, because the source doesn’t say.

How big is the change? On the midpoints, 170 down to 115, about 32 percent. Comparing the outside edges it runs anywhere from 28 percent to 38 percent. We would rather hand you both ranges than compress it into one tidy fraction that hides which two numbers we picked.

Why this is worth your attention

A softener doesn’t discover your hardness. It’s told, once, by whoever set it up, and it keeps using that number until somebody changes it.

If your unit was programmed against 160 or 180, and the city now reports 100 to 130, then the setting it’s running on is a number the city no longer prints. We aren’t going to claim that’s true of your house — nothing establishes how many softeners in Cuyahoga Falls carry an old setting, and we haven’t counted. But it’s a specific, checkable thing, and checking it’s quick.

Being set too high isn’t a dramatic failure. It’s a quiet one. The machine regenerates more often than the water calls for, and you buy salt and water to treat hardness that isn’t there any more. That’s money leaving slowly enough that nobody notices it.

At 100 to 130 ppm the current range straddles the USGS boundary between moderately hard and hard, which sits at 120 mg/L. That’s a real change in category, not just in digits.

Where the water comes from

The supply is a well field in Water Works Park, on the south bank of the Cuyahoga River, drawing from a buried valley aquifer.

The 2024 and 2025 reports say the field consists of 15 wells. The 2023 report said 18, and the city’s water department page still says 18. We’re going with 15 and telling you about the discrepancy, because the annual report is the document that gets compiled against sampling data.

On treatment, the report says the water is discharged into iron removal filters where chlorine is added to remove iron and manganese, then that roughly two-thirds of the effluent is softened and blended in a mixing tank. You will find longer descriptions of the plant elsewhere on the city’s site. We are quoting the report because the report is the document that’s maintained.

Iron and manganese matter here in a specific and limited way. The reports frame them as causes of staining and mineral buildup in home water systems, including staining of clothing. That’s what they say. If anyone tells you the iron in Cuyahoga Falls water is a taste problem or a health problem, ask which document they read it in.

The system serves roughly 55,000 people across Cuyahoga Falls, Munroe Falls and Silver Lake, per the city’s water department page.

What we would actually do here

Read the setting on the valve before touching anything else. If it’s carrying a number from an older report, correcting it costs nothing and starts saving salt immediately.

Then test the water at your tap rather than trusting any published range, including the current one. A finished-water range is a plant-side figure across a whole system. Yours is one address on it.

We do that as part of the free water test. Adjusting or rebuilding an existing unit is water softener service in Cuyahoga Falls; replacing one is water softeners.
