BUTLER COUNTY, PENNSYLVANIA · 68 MIN FROM OUR GREENVILLE OFFICE
EPA maps Connoquenessing inside Pennsylvania American Water’s Butler system, and that system’s lead record is steady: each sampling round listed from 2016 to 2025 came in under the 0.015 mg/L action level, the last two at 0.002. Local well logs run deep: sixth of 21 Butler County towns by median depth.

WHAT WE DO IN CONNOQUENESSING
Whether you’re on a private well or city water, the same crew handles the water source, the pressure, and what comes out of the tap.
The Butler system adds a polyphosphate corrosion inhibitor and adjusts pH to protect pipes, and its water carries chloramine, which a CityLux system removes. Lead at your own tap can differ from the system’s results. For homes on wells, a water test is the starting point.
Three in four logged wells in the area went at least 120 feet, and a quarter went past 225. Rock came within 25 feet in most logs, so casing is usually short and nearly all of the drilling goes into rock.
The median well here gave 13 gallons per minute, and a quarter gave 6 or less. On the weaker wells, matching the submersible pump to the well’s recovery, and sizing the pressure tank to limit starts, matters more than pump horsepower.

Pennsylvania American Water’s Butler system serves 43,286 people by EPA’s count. It draws on Oneida Reservoir, Thorn Run Reservoir and the Allegheny River, and also buys filtered water from Pennsylvania American Water’s Ellwood City system. EPA lists four lead sampling rounds, with 90th-percentile results of 0.006 mg/L in 2016, 0.0029 in 2019, and 0.002 in both 2022 and 2025. Each is under the 0.015 mg/L action level.
Those figures are measured across the system’s sampled taps, and a home’s own plumbing can change the picture. A water test at your tap is the way to know, and if it finds lead, reverse osmosis at the kitchen sink is the usual answer. The system’s polyphosphate inhibitor and pH adjustment are there to limit corrosion in the pipes.
The logs show what a new well meets. Three in four of the 736 depth logs within 5 miles went 120 feet or deeper. The Glenshaw Formation, Pennsylvanian shale, coal, sandstone and limestone, is the unit mapped at the town center.
Yields are middling: half the logs gave 13 gallons per minute or less. With a deep bore and moderate flow, the water standing in the hole acts as a reserve during heavy use, and the pump is sized so it doesn’t outrun the well. Submersible pumps and pressure tanks are chosen from the yield test at the end of drilling, and depth weighs heavily in what a new well costs.
WATER IN BUTLER COUNTY
In USGS samples from across Butler County, taken 1926–1997, 68% of wells were hard or very hard, 56% carried iron above the staining line, 86% had manganese above 0.05 mg/L. The full record, and what it means for treatment, is on the Butler County page; your own well gets its own test.

Rated 4.7 on Google across 104 reviews. Here is what working with us looks like, in a customer’s words.
“I had the pleasure of having Sam and Hunter for the installation of my new water softener, and I couldn’t be more impressed. The system is working great, and I can already notice a difference in the water quality.”

A LITTLE CLARITY
Our Greenville office (854 Mercer Rd., Greenville, PA 16125) is about 68 minutes and 48 miles by road from Connoquenessing. Service calls for Connoquenessing are scheduled from there.
Connoquenessing and the municipalities around it: Connoquenessing Township, Forward Township, Evans City, Butler Township, Penn Township, Callery, Jackson Township, Lancaster Township, Harmony, Prospect. Beyond those, the rest of the 21 Butler County communities on our service map, from the same office.
Pennsylvania’s groundwater database (PaGWIS) lists 736 domestic wells within 5 miles of Connoquenessing: the median is 165 feet deep, and the middle half fall between 120 and 225 feet. The median well was logged at 13 gallons per minute. Drillers reached bedrock at a median of 16 feet. Your own well's depth depends on the ground under your lot.
EPA lists a polyphosphate inhibitor for corrosion control, with a pH adjustment after treatment for the same purpose. Both help keep pipes and fixtures from corroding and releasing metals into the water. The system’s lead results, all under the action level, describe the system as a whole; a test at your own Connoquenessing tap shows what’s in your water.
Casing usually runs from the surface down to bedrock, and in the local logs rock came at a median 16 feet, within 8 feet in a quarter of them and by 25 feet in three in four. So casing is a short, fairly predictable part of the job. The depth of the open hole below it, where the water comes in, is the bigger variable.
