If you’ve ever turned on your faucet and wondered what’s actually in your water, you’re not alone. Many homeowners across Cincinnati and Northern Kentucky are starting to take a closer look at their water quality—and for good reason. While municipal water is treated and considered safe, that doesn’t always mean it’s as clean or ideal as you might think. At True Flow Services, we believe homeowners should understand exactly what’s coming out of their taps and how it impacts their home and health.

Where Does Cincinnati’s Water Come From?

The majority of drinking water in Cincinnati comes from the Ohio River, along with contributions from a local aquifer system. This water is treated by the Greater Cincinnati Water Works before being distributed to homes.

The treatment process removes harmful bacteria and contaminants, ensuring the water meets federal safety standards set by the Environmental Protection Agency.

However, “safe” doesn’t always mean “perfect.”

What’s Actually in Your Tap Water?

Even after treatment, your water can still contain trace elements and additives. Here are some of the most common:

Chlorine

Chlorine is added during treatment to disinfect the water and kill bacteria. While effective, it can leave behind a strong taste and odor that many homeowners notice.

Disinfection Byproducts (TTHMs & HAA5)

When chlorine reacts with organic matter, it can form byproducts like trihalomethanes (TTHMs) and haloacetic acids (HAA5). These are regulated but still present in small amounts.

Lead

Lead typically doesn’t come from the water source itself—it enters through older plumbing systems, especially in homes built before 1986. Corroded pipes or solder can introduce lead into your drinking water.

PFAS (“Forever Chemicals”)

PFAS are man-made chemicals that have been detected in water systems across the country. They are persistent and don’t break down easily in the environment.

Minerals & Hard Water Content

Water in this region often contains calcium and magnesium, which contribute to hard water. While not harmful to drink, these minerals can cause buildup in pipes and appliances.

Why “Safe” Water Isn’t Always Ideal

Municipal water must meet legal safety limits, but those limits don’t always reflect the lowest possible health risk. Regulations allow small amounts of certain substances, meaning your water can still contain contaminants—even if it’s technically compliant.

There’s also another key factor:
Water can change after it leaves the treatment plant.

As water travels through aging infrastructure and into your home’s plumbing, it can pick up additional contaminants, especially if your pipes are older or corroded.

How This Impacts Your Home

Water quality doesn’t just affect what you drink—it impacts your entire plumbing system.

Common issues homeowners experience include:

  • Mineral buildup on fixtures
  • Reduced appliance lifespan
  • Dry skin and hair from hard water
  • Metallic or chemical tastes

Over time, these small issues can lead to costly repairs or replacements.

Do You Need a Water Filtration System?

Not every home has the same water quality. Whether you need filtration depends on a few factors:

  • Age of your home (older homes = higher risk of pipe-related contaminants)
  • Noticeable taste or odor issues
  • Hard water buildup on fixtures or appliances
  • Concerns about specific contaminants like lead or PFAS

A professional water test is the best way to determine exactly what’s in your water and what solution makes the most sense.

Why Local Testing Matters

Water quality can vary not just by city, but by neighborhood—and even from house to house. The condition of your plumbing, distance from the treatment plant, and local infrastructure all play a role.

That’s why at True Flow Services, we recommend starting with accurate, local water testing before choosing any system. Check out our recent post on Water Filtration 101 to get a better understanding about what water filtration systems can work the best for you.
