BUTLER COUNTY, PENNSYLVANIA · 58 MIN FROM OUR GREENVILLE OFFICE
Harmony’s water authority treats its own surface water: EPA lists one intake and the Harmony Plant, where the water is settled, filtered and chlorinated. The local well logs show deep, slow wells. The median log nearby gave 6 gallons per minute, so for a new well, planning the pump and stored water matters as much as finding water.

WHAT WE DO IN HARMONY
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.
Authority customers get water treated with permanganate for iron and manganese, filtered, pH-adjusted to limit corrosion and chlorinated. Their report comes from the authority. A private well gets none of that, so a water test comes before choosing a FerronX system, a softener or anything else.
Extra depth here is drilled in rock, and it adds to the cost. Soil is shallow, with rock at a median 17 feet. Harmony shares second place among 21 Butler County towns by median well depth, and a quarter of logs went past 260 feet.
A quarter of wells logged in the area gave 3 gallons per minute or less. On wells like those, pump size is set by what the well can sustain, and the tank and controls are chosen to keep the pump from running dry.

EPA’s record for the Harmony Borough Water Authority shows surface water from a single intake, treated at its plant and delivered through 661 service connections. The treatment list is long. Powdered activated carbon handles taste and odor, permanganate takes on iron and manganese, and chlorine gas goes in before treatment. The plant also uses coagulation, rapid mixing, flocculation, settling and rapid sand filtration, then adjusts pH for corrosion control and adds chlorine again at the end.
At the tap, that means water with its iron and manganese taken out at the plant and chlorine carried through the pipes. Where the chlorine taste is unwelcome, a CityLux system takes the chlorine out. Customers get their water report from the authority; homes on private wells start with a water test.
The 887 yield logs within 5 miles set the scene: a median of 6 gallons per minute, 3 or less in a quarter of them, and 14 or more in only a quarter. That is low for a household, and it shifts the focus from finding a big pump to protecting the one you have.
A pump that can deliver more than the well recovers can pull the water down to its intake and run dry, which wears it out. The fix is matching: a submersible pump sized to the well’s sustained yield, a pressure tank large enough to cover short bursts of use, and controls that shut the pump off before it runs dry. The yield test at the end of drilling gives the number all of it is built around.
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.
WHY HARMONY CHOOSES CHATFIELD
Rated 4.7 on Google across 104 reviews. Here is what working with us looks like, in a customer’s words.
“Chatfield Drilling replaced a submersible pump, extended our well casing above ground, and installed a sanitary cap at our farm house. This is our first experience with a well. Both Matt and Sam were happy to answer all of our questions, no matter how small, in a way that we could understand and enabled us to make informed decisions.”

A LITTLE CLARITY
Our Greenville office (854 Mercer Rd., Greenville, PA 16125) is about 58 minutes and 44 miles by road from Harmony. Service calls for Harmony are scheduled from there.
Harmony and the municipalities around it: Zelienople, Jackson Township, Lancaster Township, Marion Township, Evans City, Franklin Township, Connoquenessing, Forward Township, Callery, Cranberry Township. Beyond those, the rest of the 21 Butler County communities on our service map, from the same office.
Pennsylvania’s groundwater database (PaGWIS) lists 931 domestic wells within 5 miles of Harmony: the median is 175 feet deep, and the middle half fall between 120 and 260 feet. The median well was logged at 6 gallons per minute. Drillers reached bedrock at a median of 17 feet. Your own well's depth depends on the ground under your lot.
EPA lists six lead sampling rounds for the authority between 2016 and 2025. The 90th-percentile results ranged from 0.002 to 0.005 mg/L, with the latest at 0.0022, and every round was under the 0.015 mg/L action level. Those are system-wide figures; your own tap can differ with its plumbing, and reverse osmosis at the sink is the usual answer if a test finds lead.
It can be, if set up for the well. A constant-pressure pump ramps up to hold pressure, and on a well where a quarter of local logs gave 3 gallons per minute or less, it can outrun the water refilling the bore. Limiting its top output to the well’s recovery, with protection against running dry, avoids that. The yield test on your own well sets the limits.
