WATER TREATMENT · OUR GREENVILLE OFFICE IS IN TOWN
Greenville’s borough water is Shenango River water the plant has already treated for iron and dosed with chloramine. The wells around town hit rock at a median 18 feet, and they get no treatment until you add it.
Serving our communities since 1967
USGS sampled Mercer County wells between 1928 and 2023. That shows what is common here, and your own water test sets the size of the system.

WHAT WE INSTALL IN GREENVILLE
The Equipment Greenville
Water Tends to Need.
Chatfield Water Systems is one line, with one system per problem. Your water test decides which ones you need and in what order; the county record shows which are likely.
- HARD AT THE MEDIAN
Water softeners
59% of sampled Mercer County wells were hard or very hard, at a median of 7.6 grains per gallon. Your softener is sized to your own test.
EXPLORE - 58% OF WELLS ABOVE THE IRON LINE
Iron & manganese removal
58% of sampled wells were above 0.3 mg/L of iron and 54% above the manganese line. The FerronX goes in at the point of entry, ahead of the softener.

Chlorine removal
Greenville’s public water is disinfected surface water, so the chlorine is still in it at the tap. The CityLux takes it out of the whole supply.

A water test
Every system above starts with a test of your well or your tap water, from our Greenville office, in town. What it finds decides which equipment you need and the order it goes in.

What Greenville Water Says,
and What We Do About It.
What the borough plant does to river water
The borough system, listed with EPA as Aqua PA Greenville, draws from the Shenango River and serves about 8,600 people through 3,175 connections. Permanganate goes in for iron, and powdered activated carbon for taste and odor. The particle-removal steps are rapid mix, coagulation, flocculation, settling and rapid sand filters, with a pH adjustment ahead of filtration. Chlorine is added before and after, fluoride is added, and a polyphosphate inhibitor is fed to protect pipes.
The step you meet at the faucet is chloramine, entered on the list for disinfection by-product control. It lingers in the pipes longer than plain chlorine, and a CityLux removes both at the point of entry. The chlorine taste page explains the taste it can leave.
Four lead rounds, all under the action level
EPA publishes the system’s lead 90th percentile, the level that 90 percent of sampled homes came in at or under. The 2016 and 2019 rounds are recorded as 0 mg/L. The 2022 round was 0.00129 mg/L and the 2025 round 0.00084 mg/L. All four sit under the 0.015 mg/L action level.
Those figures describe taps across the borough, not your kitchen. Lead at a faucet usually comes from the plumbing between the main and the tap, the part the polyphosphate inhibitor is there to protect, so one house can read differently. A certified-lab lead test answers it for yours. If it finds lead, reverse osmosis at the kitchen sink is the usual answer.
Township wells and shallow bedrock
For homes on wells, PaGWIS holds 905 logs with a recorded depth within 5 miles. The median well is 105 feet, and the middle half run from 80 to 145. Bedrock is close to the surface: a median of 18 feet down, 12 to 35 for the middle half. The rock mapped at the town center is the Cuyahoga Group’s siltstone, shale and sandstone, from the Mississippian. Yields have a median of 25 gallons per minute and a middle half of 15 to 40.
Well logs cover depth, rock and yield, and none of it shows what is dissolved in the water. Orange stains point to iron, which the FerronX Iron System removes along with manganese. A rotten-egg smell calls for the CataPure Carbon System. Our crew works out of the Greenville office, and treatment for a township well starts with a test on site.
The Mercer County record
USGS samples from Mercer County wells, taken 1928–2023: 59% of wells hard or very hard, 58% over the iron line, 9% below pH 6.5. The full record, measure by measure, is on the Mercer County water treatment page.

A LITTLE CLARITY
Greenville Questions.
Straight Answers.
Is there chloramine in Greenville’s borough water?
Yes. Chloramines appear on the plant’s EPA treatment list, entered for disinfection by-product control, and chloramine holds up in the pipes longer than chlorine alone. A CityLux at the point of entry removes both chlorine and chloramine, so the shower, the laundry and the kitchen all get the same water.
Does the borough plant in Greenville soften the water?
Softening isn’t among the steps EPA lists for it. The plant treats for iron, for taste and odor, and for particles, and it adjusts pH ahead of filtration, but hardness isn’t named anywhere on the list. A hardness reading at your own tap tells you whether softening is worth adding. If it is, the CityLux does it while removing the chloramine.
What should a well owner near Greenville test for first?
Start with what you can see or smell. Orange or brown staining points to iron and often manganese, and a sulfur smell points to hydrogen sulfide. The test at your tap covers those first checks, and a certified lab handles bacteria and nitrate. Equipment gets chosen only after those results are in.
Do you test water in Greenville?
Yes. Chatfield’s water test and consultation cover Greenville from our Greenville office, which is in town. The test measures what is in your water and at what level, and any equipment it points to is quoted after the results.
