Clean, confident drinking water in Delhi
Delhi sits just south of Turlock, close enough that our trucks are already in the neighborhood. Families here want the same things everyone does: a glass of water that tastes clean, coffee and baby formula they don’t have to think twice about, and a home free of scale. We help Delhi homes get there with a free test at the tap and a system built around the results.
What’s in Delhi’s water
Delhi County Water District pumps all of the town’s water from four groundwater wells. [Delhi County Water District 2025 Consumer Confidence Report] Its latest report shows no violations, and it also shows why testing matters here. Nitrate, which comes from fertilizer and septic sources in farm country, averaged well under the limit but reached it in at least one sample. Naturally occurring arsenic ran close to its limit at the high end. And two PFAS compounds, PFOS and PFHxS, were detected above the state’s notification levels. [Delhi County Water District 2025 Consumer Confidence Report] None of these change how the water looks or tastes, so a lab-backed test is the only way to know what reaches your faucet.
The report doesn’t list hardness, so we measure it at your home before recommending anything for scale. Outside the district, many homes and orchards run on private wells, and those need a full test of their own.

How we help Delhi homes
- Reverse osmosis at the kitchen sink is the most common starting point. It reduces arsenic, nitrate and PFAS in the water you drink and cook with.
- Nitrate removal for the whole house. Anion exchange is our primary and most effective method for nitrate; RO reduces it in drinking water, though less effectively.
- Well water treatment for homes on private wells, including UV disinfection when a test shows bacteria.
- A water softener or saltless conditioner only if your test shows enough hardness to matter. Our softeners include built-in filtration, which most don’t. Don’t want salt? Ask about saltless options.
Softener, saltless, backwashing carbon and sediment filtration tanks carry a lifetime limited tank warranty.
Looking ahead
Merced County approved the Bradbury Ranch master plan on Delhi’s east side in 2023, so more families may call Delhi home in the years ahead. [Turlock Journal: County approves 1,000 housing units near Delhi] Whether your home is decades old or yet to be built, the water story starts with a test.

Delhi water FAQs
Is there nitrate in Delhi’s water?
Yes. Delhi County Water District’s 2025 report shows nitrate averaging 5.96 mg/L, with one or more samples at 10.6 mg/L against a 10 mg/L limit; no violation is listed. Whole-house anion exchange is our primary method for nitrate, and RO can reduce it in drinking water, though less effectively. Families with infants usually ask about nitrate first.
Does Delhi water have PFAS?
The district’s latest report lists two PFAS compounds, PFOS and PFHxS, above California’s notification levels. They aren’t listed as violations, but many families prefer a drinking-water system that reduces them. RO at the kitchen sink is one of the most effective options.
Do Delhi homes need a water softener?
Not always. The district’s report doesn’t list hardness, so we measure it at your tap. If your water is hard enough to cause scale, we’ll show you softener and saltless options side by side.
Do you test private wells around Delhi?
Yes. We test for nitrate, arsenic, bacteria, iron and more, then design well water treatment around the results.
