BUTLER COUNTY, PENNSYLVANIA · 71 MIN FROM OUR GREENVILLE OFFICE
Wells around Callery go deep and give modest flow. Three in four logs reached at least 125 feet, and three in four also yielded 15 gallons per minute or less. A new well here is planned around both facts: a longer bore, and a pump matched to a well that won’t give water quickly.

WHAT WE DO IN CALLERY
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.
Butler County’s USGS record puts median iron at 0.75 mg/L, above the 0.3 mg/L line where orange staining starts. That’s a county figure from older samples, so a test of your own well comes first, and the FerronX Iron System handles iron and manganese if the test calls for it.
Wells here go deep. Callery ties for second of 21 Butler County towns by median depth, and a quarter of logged wells reached 240 feet or more. Soil is thin by comparison, 17 feet to rock at the median, so almost all of that footage is drilled in rock.
The median yield is 10 gallons per minute, and only a quarter of logs top 15. A submersible pump sized to the well’s recovery, paired with a pressure tank that limits starts, gives steadier water than one sized to the fixtures.

Of the 834 logs near Callery that record yield, half gave 10 gallons per minute or less and a quarter gave 5 or less. A household can run on numbers like that, but the well sets the pace rather than the fixtures.
Depth helps. In a long bore, a column of water stands above the pump, and it carries the house through heavy use while the rock catches up. Agree with the driller in advance how far to keep going if a new well comes in light, because every foot adds to the cost of a new well. Pump system design covers matching pump and tank to the well.
Geologic maps place the Glenshaw Formation at Callery’s center: Pennsylvanian shale, coal, sandstone, limestone and other clastic rock. Soil over it is shallow. Among the 609 logs that note bedrock, the median depth to rock is 17 feet, a quarter reached it within 10, and three in four within 25.
Casing usually runs from the surface down to rock, so it’s a small part of most wells here. The bigger unknown is how far into the rock the bore goes before it crosses enough water, and the driller’s log records each layer and each water-bearing zone on the way down. Residential well drilling explains how that’s handled, and on an existing well a well inspection measures what the bore delivers.
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 CALLERY 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 71 minutes and 51 miles by road from Callery. Service calls for Callery are scheduled from there.
Callery and the municipalities around it: Evans City, Adams Township, Forward Township, Mars, Seven Fields, Cranberry Township, Jackson Township, Valencia, Connoquenessing, Harmony. Beyond those, the rest of the 21 Butler County communities on our service map, from the same office.
Pennsylvania’s groundwater database (PaGWIS) lists 877 domestic wells within 5 miles of Callery: the median is 175 feet deep, and the middle half fall between 125 and 240 feet. The median well was logged at 10 gallons per minute. Drillers reached bedrock at a median of 17 feet. Your own well's depth depends on the ground under your lot.
Usually, with the right setup. Peak demand comes in short bursts, and water stored in a deep bore covers them while the well recovers. The pump should match the well’s recovery rather than the number of bathrooms, and the pressure tank should be sized to limit starts. A quarter of local logs gave 5 gallons per minute or less, and that’s where the matching matters most.
Watch for pressure that fades during long showers or laundry, air spitting from faucets, or a pump that seems to run constantly. With a quarter of local logs at 5 gallons per minute or less, some wells here run close to their limit. A well inspection measures the flow and checks the pump and tank, so the fix matches the cause.
