Keyes is a short drive down Highway 99 from our Modesto shop, right between our Ceres and Turlock customers. What Keyes families ask us for most is simple: drinking water they can trust for the kids, the coffee pot and the dog bowl, without hauling cases of bottled water home. We start with a free test at your kitchen sink and build from there.
What’s in Keyes water
Keyes Community Services District supplies the town from four groundwater wells. [Keyes Community Services District 2025 Consumer Confidence Report] Its 2025 report marks 1,2,3-TCP, a leftover from old farm soil fumigants, above the drinking-water standard. The district says it is building an activated carbon treatment system, and that system can be adapted for chromium-6 if needed. [Keyes Community Services District 2025 Consumer Confidence Report] Naturally occurring arsenic and chromium-6 are present below their limits, though one chromium-6 sample at Well 10 came in high; the district believes that result may have been an error, and its follow-up sample was below the limit. [Keyes Community Services District 2025 Consumer Confidence Report]
None of these can be seen, tasted or smelled. Until the district’s treatment is running, a drinking-water system at the kitchen sink is the most direct way to add protection.
On the comfort side, Keyes water is on the soft end for the Valley, so many homes don’t need a softener. That makes the conversation simpler: focus on the water you drink.

Local water challenges in Keyes
- 1,2,3-TCP above the standard while the district builds treatment
- Naturally occurring arsenic and chromium-6 below the limits
- Nitrate that spikes in some samples, plus private wells around town that need their own test
How we help Keyes homes
- Reverse osmosis with carbon stages at the kitchen sink, for drinking and cooking water. It reduces arsenic, chromium-6 and nitrate along with a wide range of dissolved minerals.
- A whole house water filter if you’d like carbon filtration at every tap, using options such as backwashing carbon or a large-capacity cartridge.
- Well water treatment and nitrate removal for rural homes on private wells.
- A water softener or saltless conditioner only if your test shows the hardness to justify it.
Backwashing carbon and sediment filtration tanks, like our softener and saltless tanks, carry a lifetime limited tank warranty.

Keyes water FAQs
Is there TCP in Keyes water?
Yes. Keyes CSD’s 2025 report lists 1,2,3-TCP at 0.034 ppb on average, with a high of 0.1347 ppb, against a 0.005 ppb standard, and marks it as a violation. The district is building activated carbon treatment. Reverse osmosis with carbon stages at the kitchen sink is a common way to add protection in the meantime.
Do I need a water softener in Keyes?
Often not. Keyes water is on the soft side for the Central Valley, so most families start with drinking-water filtration. We test hardness at your tap and only recommend softening or conditioning if it’s worth it.
Is there chromium-6 in Keyes water?
Yes, at levels below the state limit on average. One sample at a single well came in high, and the district’s follow-up was below the limit. RO reduces chromium-6 in drinking water.
Do you serve homes on wells around Keyes?
Yes. We test private wells for nitrate, arsenic, bacteria and more, then design well water treatment around the results.
