VENANGO COUNTY, PENNSYLVANIA · 63 MIN FROM OUR GREENVILLE OFFICE
The Cuyahoga Group is mapped under Cooperstown: Mississippian siltstone, shale and sandstone. Wells drilled around the town run second-deepest of ten Venango County towns by median, and the middle half of 498 yield logs falls between 12 and 30 gallons a minute, so depth, more than flow, is the number to plan around.

WHAT WE DO IN COOPERSTOWN
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.
EPA lists two steps for Cooperstown Water Company, both disinfection: chlorine and 4-log treatment of viruses, which kills nearly all of them. It lists no iron removal or softening. Homes on private wells nearby start with a water test to see what their own water carries.
Rock sits at a median 27 feet in the 374 logs that record it and at 45 or more on a quarter of them. A quarter of the 514 depth logs went past 143 feet, so plan for a well that may run well beyond the median.
A median yield of 20 gallons a minute, with only a quarter of logs at 12 or less, suits a standard submersible pump and pressure tank. On the deeper wells the pump often hangs lower, so the pump, wire and drop pipe are chosen for depth as much as for flow.

PaGWIS records

Wells around Cooperstown run deep for Venango County. The median of 103 feet ranks second of ten towns, and three quarters of the 514 depth logs went past 70 feet. Rock itself is moderate, a median 27 feet down, and a quarter of the 374 logs that note it found rock within 15 feet. Since casing usually stops at rock, most of a typical well’s depth is drilling in rock, not casing.
Footage drives the bill for a new well, so the cost page is worth a look before you plan one. Residential drilling walks through the permit, the drilling and the pump, and the Greenville office drills with air rotary or cable tool rigs as the ground calls for.
EPA lists Cooperstown Water Company, a private system named for the town, drawing groundwater from one active well, Well #4. Two treatment plants appear on its record, and the steps listed are chlorine and 4-log treatment of viruses, the standard for wiping out nearly all of them. The company serves about 360 people through 128 connections, and its customers get their water report from the company.
Homes on their own wells rely on a water test instead. The county’s USGS samples are few, 7 wells for iron and 5 for pH, so they say little about one property. A test on site or through a certified lab does, and it shows what equipment fits, whether that’s sediment filtration, iron removal or nothing at all.
WATER IN VENANGO COUNTY
In USGS samples from across Venango County, taken 1928–2023, 43% of wells were hard or very hard, 43% carried iron above the staining line, 40% had manganese above 0.05 mg/L. The full record, and what it means for treatment, is on the Venango County page; your own well gets its own test.

A LITTLE CLARITY
Our Greenville office (854 Mercer Rd., Greenville, PA 16125) is about 63 minutes and 41 miles by road from Cooperstown. Service calls for Cooperstown are scheduled from there.
Cooperstown and the municipalities around it: Jackson Township, Canal Township, Oakland Township, Sugarcreek, Wayne Township, Plum Township, Utica, Frenchcreek Township, Franklin, Troy Township. Beyond those, the rest of the 10 Venango County communities on our service map, from the same office.
Pennsylvania’s groundwater database (PaGWIS) lists 514 domestic wells within 5 miles of Cooperstown: the median is 103 feet deep, and the middle half fall between 70 and 143 feet. The median well was logged at 20 gallons per minute. Drillers reached bedrock at a median of 27 feet. Your own well's depth depends on the ground under your lot.
The Cuyahoga Group mapped at the town center is siltstone, shale and sandstone, and the finer-grained siltstone and shale hold water mainly in fractures. A bore that crosses several open fractures can yield well, while one a short distance away that misses them gives less. Even so, the local logs keep the middle half between 12 and 30 gallons a minute, and a quarter came in at 12 or less.
Yes. A well inspection looks at the wellhead, pump and pressure tank, and a water test, on site or through a certified lab, shows what the water carries. With wells here running a median 103 feet, knowing the pump’s condition before closing is useful. The Greenville office does both; call (724) 588-2652.
