You turn on the tap every day without thinking twice. But if you've noticed scale buildup on your faucets, orange stains in your tub, or a faint chemical smell from the tap, your water is trying to tell you something.

Columbus tap water meets all federal safety standards — but "safe to drink" and "good for your home" are two very different things. Here's what Central Ohio homeowners actually find when they test their water, and why a free in-home test is worth your time this fall.

Columbus gets its water from the Scioto and Olentangy rivers, treated at the Dublin Road and Hap Cremean Water Plants. The city publishes an annual water quality report, and by the numbers, the water is safe.

But safe doesn't mean problem-free.

Columbus water is hard. Very hard. The city's water typically runs between 12 and 18 grains per gallon (gpg) — well above the 7 gpg threshold where most water treatment professionals recommend a softener.

What does that mean for your home?

• Scale buildup on faucets, showerheads, and inside appliances
• Reduced efficiency in water heaters (scale acts as insulation, forcing the heater to work harder)
• Spotty dishes and cloudy glassware from the dishwasher
• Dry skin and dull hair after showering — calcium and magnesium strip moisture
• Shortened appliance lifespan for washing machines, dishwashers, and ice makers

Most Columbus homeowners don't realize their water heater is working 20–30% harder than it should because of scale. Over a 10-year period, that adds up to hundreds of dollars in wasted energy.

Unlike many cities that use chlorine, Columbus treats its water with chloramines — a combination of chlorine and ammonia. Chloramines are more stable than chlorine and don't dissipate as quickly, which is why you can sometimes smell or taste them even after the water has been sitting out.

Chloramines are considered safe at the levels Columbus uses. But they do affect taste and smell, and they can be harder on fish tanks and home brewing setups than regular chlorine.

Standard carbon filters remove chlorine but are less effective against chloramines. If taste and odor are a concern, you'll want a filter specifically rated for chloramine removal.

If you live in an older Columbus neighborhood — Clintonville, Bexley, German Village, Grandview — you may have iron in your water. This can come from aging municipal pipes or, if you're on a private well, from the ground itself.

Signs of iron in your water:

• Orange or rust-colored stains in sinks, tubs, and toilets
• Metallic taste in drinking water
• Reddish tint when you fill a white bathtub
• Orange staining on laundry, especially whites

Iron levels above 0.3 mg/L are noticeable and can cause staining. Levels above 1–2 mg/L typically require treatment.

PFAS (per- and polyfluoroalkyl substances) — sometimes called "forever chemicals" — have been detected in water supplies across Ohio. Columbus's water treatment plants have implemented additional filtration to address PFAS, and current levels are below EPA action thresholds.

That said, if you have young children, are pregnant, or have health concerns, understanding your specific PFAS exposure is worth knowing. A reverse osmosis system is the most effective residential treatment for PFAS removal.

The city tests the water at the treatment plant and at various points in the distribution system. But by the time water reaches your tap, it has traveled through miles of pipes — some of them old.

Your water quality at the tap can differ from what the city reports, especially if:

• Your home was built before 1986 (possible lead solder in pipes)
• You're in a neighborhood with older infrastructure
• You have a private well
• You've noticed changes in taste, smell, or appearance

A city water report tells you what's in the water when it leaves the plant. An in-home test tells you what's coming out of your faucet.

A professional in-home water test from Pure Aqua Columbus checks for the issues most relevant to Central Ohio homes:

• Total hardness (grains per gallon) — the most common issue in Columbus
• Iron and manganese — tested for both dissolved and particulate forms
• pH — acidic water corrodes pipes; alkaline water can cause scale
• Chlorine and chloramine levels — taste, odor, and filtration implications
• Total dissolved solids (TDS) — an overall indicator of mineral load
• Bacteria (for well water customers)

The test takes about 20–30 minutes. A certified water specialist comes to your home, tests right at the tap, and explains the results in plain English — not lab jargon.

If your water has issues we can address, we'll explain your options honestly. If your water is fine, we'll tell you that too. There's no sales pressure and no obligation to purchase anything.

We've tested water across Franklin, Delaware, Licking, Fairfield, and Union counties. Here's what we see most often:

Dublin and Powell: Very hard water (often 15–18 gpg), occasional iron. Softeners are common and effective here.

Westerville and New Albany: Hard water, generally good otherwise. Many homeowners add a softener and a drinking water filter.

Hilliard and Grove City: Hard water, some iron in older neighborhoods. Combination softener/iron filter systems work well.

Gahanna and Reynoldsburg: Hard water, occasional chloramine taste complaints. Whole-house carbon filtration plus softening is a popular combination.

Well water areas (rural Franklin, Delaware, Licking counties): Iron, hardness, and bacteria are all common. Well water requires more comprehensive testing.

Hard water isn't a health risk — but it is an expensive inconvenience that compounds over time.

A water heater running in hard water loses efficiency every year as scale builds up inside the tank. A study by the Water Quality Research Foundation found that water heaters operating in hard water conditions (15+ gpg) lost up to 48% of their efficiency over 15 years compared to units operating with softened water.

Washing machines, dishwashers, and coffee makers all have shorter lifespans in hard water. You use more soap and detergent because hard water reduces lather. You spend more time cleaning mineral deposits off fixtures and glass.

Soft water pays for itself — typically within 3–5 years for most Columbus households — through reduced energy costs, longer appliance life, and lower soap and detergent use.

If any of these apply to you, a free water test is worth scheduling:

• You've noticed scale buildup on faucets or showerheads
• Your dishes come out of the dishwasher with white spots or film
• Your skin feels dry or your hair looks dull after showering
• You've seen orange or rust-colored stains in sinks or tubs
• Your water has a chemical smell or taste
• You're on a private well and haven't tested in the past year
• You're buying a new home and want to know what you're working with

Even if you haven't noticed any of these issues, knowing your water quality is useful information. Many homeowners are surprised to learn how hard their water actually is.

Through October 15, Pure Aqua Columbus is offering free in-home water tests to Columbus-area homeowners. Spots are limited — we schedule these by appointment and can only take a certain number each week.

Claim your free water test this fall before spots fill up. The test is completely free, takes about 30 minutes, and comes with zero obligation. You'll walk away knowing exactly what's in your water — and what, if anything, to do about it.

We serve Columbus and 52+ surrounding suburbs including Dublin, Westerville, Hilliard, Grove City, Gahanna, New Albany, Powell, Pickerington, Lewis Center, and more.
