BUTLER COUNTY, PENNSYLVANIA · 54 MIN FROM OUR GREENVILLE OFFICE
Near Eau Claire, the drill is in rock almost from the start: half the logs reached bedrock within 12 feet and three in four by 20. Bores went on from there, a quarter of them past 240 feet, so nearly every foot you pay for is rock and depth is the number to plan around.

WHAT WE DO IN EAU CLAIRE
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.
A water test of a well here usually looks at hardness, iron, manganese and pH, the four measures in Butler County’s USGS record. The results also set the order: iron and manganese come out first, then a LuxSoft water softener handles whatever hardness is left.
Depth is what moves the price on an Eau Claire well. The town sits mid-list, 13th of 21 Butler County towns by median well depth, but the deep end runs long, with a quarter of logs past 240 feet. With rock so shallow, casing is usually short.
The median yield is 12 gallons per minute, three in four logs gave at least 8, and a quarter gave 25 or more. A well at the low end needs its pump matched to recovery; one near the top can be sized to the house.

Of the 159 logs around Eau Claire that record depth to bedrock, a quarter hit rock within 5 feet and three in four within 20. That is thin cover. The casing usually runs down through it and seats in the rock, so on most lots it’s one of the smaller parts of the job, and the open hole below is where the water comes in.
The rock mapped at the town center is the Allegheny Formation: Pennsylvanian sandstone, shale, limestone, clay and coal. In these layered rocks, water sits in fractures and along bedding planes, and the driller’s log notes each layer and each water-bearing zone. Well drilling covers the air rotary and cable tool methods, and what a new well costs explains how depth adds up.
Butler County’s USGS record is the nearest guide to what’s in local wells, and it points three ways. Hardness had a median of 9.1 grains per gallon, with 68% of 28 wells hard or very hard. Iron was over the staining line in 56% of 27 wells, and manganese over 0.05 mg/L in 86% of 14.
Those samples are old and few, so they set the questions rather than the answers. Your own water test fills them in. Where iron and manganese show up, the FerronX Iron System goes first, so the metals don’t foul the softener’s resin; a LuxSoft water softener then takes care of the hardness.

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 EAU CLAIRE CHOOSES CHATFIELD
Rated 4.7 on Google across 104 reviews. Here is what working with us looks like, in a customer’s words.
“We bought a new home November 1st, 2024 and low and behold it had a collapsed well. After several quotes, we chose Chatfield drilling, and we’re glad we did! Matt & his team arrived quickly to assess the situation, and formulate a plan to get the H2O flowing again. Even through the holidays, they did not waiver. Eric their driller worked hard in the brutal NE Ohio cold to pound a well for us. We are beyond pleased, and have fantastic water!”

A LITTLE CLARITY
Our Greenville office (854 Mercer Rd., Greenville, PA 16125) is about 54 minutes and 41 miles by road from Eau Claire. Service calls for Eau Claire are scheduled from there.

Pennsylvania’s groundwater database (PaGWIS) lists 246 domestic wells within 5 miles of Eau Claire: the median is 145 feet deep, and the middle half fall between 91 and 240 feet. The median well was logged at 12 gallons per minute. Drillers reached bedrock at a median of 12 feet. Your own well's depth depends on the ground under your lot.
Ask for a well inspection: it checks the pump, its controls and the pressure tank, measures the flow, and tests the water. Around Eau Claire, a quarter of logged wells gave 8 gallons per minute or less and a quarter 25 or more, so the measured flow is worth knowing before you buy.
A quarter of logged wells did, so it’s worth planning for. The bore keeps going until it crosses enough water, and some spots take longer to get there. Before drilling, settle how far you’re willing to go and how extra footage would be billed. A deeper well can also mean a lower pump setting, which a submersible pump is built for.
