Better water for a growing Merced
Merced is building. New neighborhoods keep filling in north of town, the University Community plan south of UC Merced was approved in 2023, and Merced added more housing in 2025 than any other city in Merced County. [California Department of Finance E-1 population and housing estimates (2026)] Whether you just closed on a new build or have lived off Olive Avenue for twenty years, the goal is the same: showers that rinse clean, glassware that comes out clear, and drinking water you pour without a second thought.
Liquid Solutions has served the Central Valley since 1996, and Merced is the next stop down Highway 99 from our Modesto shop and our customers in Turlock and Hilmar. We start every Merced job the same way: a free water test at your kitchen sink.
Why Merced water varies from home to home
All of Merced’s city water is groundwater, pumped from 21 wells spread across town. [City of Merced 2024 Water Quality Report] Each well draws a slightly different mix of minerals, so hardness, taste and dissolved solids can differ noticeably between neighborhoods. Some homes see light film on the shower glass; others fight white crust on faucets and a water heater that wears out early. The city adds chlorine to keep the water safe in the pipes, and that is the faint pool smell some families notice in the shower and the coffee.
The city’s report shows its water meets federal and state standards. It also lists naturally occurring arsenic and chromium-6 below their limits, which is why many Merced families add a dedicated drinking-water system at the kitchen sink. [City of Merced 2024 Water Quality Report] Outside city limits, many homes run on private wells, and those need a full test of their own.

Local water challenges in Merced
- Hard water that changes by well: scale on fixtures, glass and water heaters
- Chlorine taste and smell in showers, coffee and ice
- Naturally occurring arsenic and chromium-6, both below the legal limits in city water
- Nitrate, iron and other well-water issues on rural properties outside the city system
How we help Merced homes
Every recommendation starts with your test results, not a package. Depending on what we find, a Merced home might use:
- A water softener for scale and the feel of soft water. Our softeners include built-in filtration, which most softeners don’t, so one system softens and improves taste and smell.
- A whole house water filter for chlorine taste and odor at every tap, using options such as backwashing carbon or a large-capacity cartridge.
- Reverse osmosis at the kitchen sink for crisp drinking and cooking water. RO reduces arsenic and chromium-6 along with a wide range of dissolved minerals.
- Well water treatment for homes on private wells.
Softener, saltless, backwashing carbon and sediment filtration tanks carry a lifetime limited tank warranty.

Merced water FAQs
Is Merced water hard?
Moderately hard on average, and much harder at some wells. The city’s latest available report lists an average of 115.4 mg/L with a range of 59 to 260 mg/L, so your neighborhood matters. A free test at your tap tells you exactly where you fall.
Does Merced water have arsenic or chromium-6?
Both occur naturally in Merced’s groundwater, and the city reports both below the legal limits. If you’d like an extra layer of protection for drinking and cooking, reverse osmosis at the kitchen sink reduces both.
Why does my Merced tap water smell like chlorine?
The city adds chlorine to keep water safe on its way through the pipes. A whole house filter with carbon reduces the taste and smell at every faucet and shower, and RO polishes drinking water further.
Do you install water softeners in new Merced homes?
Yes. New construction is a great time to add a softener or saltless conditioner, before scale reaches new fixtures and appliances. We test first and size the system to your home.
Do you work on private wells around Merced?
Yes. Rural wells can carry nitrate, iron, manganese or bacteria that city water doesn’t. We test and design well water treatment around the results.
