VENANGO COUNTY, PENNSYLVANIA · 42 MIN FROM OUR GREENVILLE OFFICE
Wells near Polk come in shallower than those around most Venango County towns, ninth of ten by median depth, with three quarters of 584 logs finishing at 120 feet or less. Yields hold up anyway, at a median 20 gallons a minute, so a new well here tends to be a comparatively short bore with a workable supply.

WHAT WE DO IN POLK
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.
Venango County’s few USGS samples lean acidic, so pH is worth testing on a Polk well. If it runs low, a calcite neutralizer raises it before the water reaches copper plumbing, and a water test shows whether iron calls for a FerronX Iron System too.
Of the 409 logs that note bedrock, half hit it within 24 feet and three quarters within 40. On most lots, then, the rig is into rock early, and the finished depth, far more than the soil above, sets the footage.
Half of the 561 yield logs show 20 gallons a minute or more, and only a quarter fall to 12 or less. At these depths a submersible pump is the usual choice, and the size of the pressure tank sets how often it starts.

PaGWIS records

The Cuyahoga Group, Mississippian siltstone, shale and sandstone, is mapped at the town center, and the logs within 5 miles describe fairly shallow wells around it. A quarter of the 584 depth records stopped at 59 feet or less, and only a quarter went past 120. Among ten Venango County towns, only one has a shallower median.
Shallower wells change the arithmetic of a new well. With casing usually down to rock and the rest open bore, a shorter total depth keeps the footage down, though what a well costs still depends on the lot. The cost page lays out the pieces. For an older well that has lost output, a well inspection shows whether the well, the pump or the tank is at fault.
Venango County has USGS pH results for only 5 wells, a pointer rather than a reading of your water. Even so, they stand out. The median was 6.3, and 60% of samples sat below 6.5, where water tends to corrode copper plumbing. Blue-green stains in sinks and tubs are the usual sign.
One test of your own well matters more than any county median, so ask for pH when your water is tested, on site or through a certified lab. If the result is low, a calcite acid neutralizer raises it at the point of entry. If iron turns up as well, a FerronX Iron System goes in line with it.
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.
WHY POLK 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 42 minutes and 29 miles by road from Polk. Service calls for Polk are scheduled from there.
Polk and the municipalities around it: Frenchcreek Township, Mineral Township, Victory Township, Sandycreek Township, Franklin, Utica, Sandy Lake Township, Mill Creek Township, Sugarcreek, Canal 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 584 domestic wells within 5 miles of Polk: the median is 90 feet deep, and the middle half fall between 59 and 120 feet. The median well was logged at 20 gallons per minute. Drillers reached bedrock at a median of 24 feet. Your own well's depth depends on the ground under your lot.
Jet pumps suit shallow wells where the water sits close to the surface. A drilled well around Polk, where the median depth is 90 feet, usually takes a submersible pump set down in the well, and yields near 20 gallons a minute leave room to size it for the house. The Greenville office installs and repairs both types.
From PaGWIS, the Pennsylvania groundwater database kept by DCNR, the state natural resources department, which holds drillers’ logs. The figures here use the logs within 5 miles of the town center: 584 for depth, 561 for yield and 409 for bedrock. They describe the area, not any one lot, and the log from your own well records what the driller actually found.
