MERCER COUNTY, PENNSYLVANIA · 31 MIN FROM OUR GREENVILLE OFFICE
West Middlesex is the borough at the south end of the Shenango Valley, with Shenango and Lackawannock townships’ farms around it and the Ohio line a few minutes west. Most homes outside the borough are on private wells, and treating that water is what West Middlesex homeowners ask us about most. Chatfield comes from our Greenville office.

WHAT WE DO IN WEST MIDDLESEX
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.
Wells around West Middlesex carry the county’s iron and hardness, with sulfur smell and manganese in some. A water test shows what a home needs before anything is installed. Most often it is a FerronX ahead of a softener, with a carbon filter between them where there is smell.
New wells for homes and farms in Shenango, Lackawannock, and Wilmington townships, drilled with air rotary or cable tool as the ground calls for. PA DEP permitting is part of the job, along with setting the casing and pump and testing water flow before the rig leaves.
Around West Middlesex we service well pumps, switches, and tanks, whether the problem is low pressure, cycling, or no water. The crew diagnoses the system as a whole, replaces the part that failed, and carries the common sizes so most repairs finish in one visit.

West Middlesex has the deepest median well of 15 Mercer County towns. Of the 450 logs within 5 miles, a quarter reached 145 feet or more.
Rock itself isn’t far down. The 278 logs that note it put bedrock at a median 24 feet, with the middle half from 14 to 50, so a typical hole here spends most of its length in rock below a moderate run of casing. The rock mapped under the town is shale, siltstone and sandstone of the Cuyahoga Group. More footage in rock means more drilling, which shows in drilling cost, and the residential drilling page walks through how a well gets drilled.
Yield runs modest and tightly grouped: a median of 15 gallons a minute across 364 logs, with the middle half between 10 and 20. A deep hole helps a well like that in one way: water standing in the bore acts as storage the pump can draw on during a burst of use, and the well refills after. How much storage there is depends on where the water stands, which is measured in your own well.
A submersible pump sized under the yield, with a pressure tank large enough to stretch each run, makes the most of it. Where a house takes Aqua PA Shenango Valley water instead, there is no well pump to size, and West Middlesex water treatment covers that supply.
WATER IN MERCER COUNTY
In USGS samples from across Mercer County, taken 1928–2023, 59% of wells were hard or very hard, 58% carried iron above the staining line, 54% had manganese above 0.05 mg/L. The full record, and what it means for treatment, is on the Mercer County page; your own well gets its own test.
WHY WEST MIDDLESEX 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
A softener with a FerronX ahead of it is the common pairing here, because iron and hardness travel together in the county’s wells. Sulfur smell adds a carbon filter, and a coliform result adds a UV lamp. The water test decides which, and in what order.
Yes. Residential and agricultural wells across southern Mercer County, with the method matched to the ground, PA DEP permit assistance, and a flow test as part of the job.
Our Greenville office (854 Mercer Rd., Greenville, PA 16125) is about 31 minutes and 17 miles by road from West Middlesex. Service calls for West Middlesex are scheduled from there.

Pennsylvania’s groundwater database (PaGWIS) lists 450 domestic wells within 5 miles of West Middlesex: the median is 110 feet deep, and the middle half fall between 80 and 145 feet. The median well was logged at 15 gallons per minute. Drillers reached bedrock at a median of 24 feet. Your own well's depth depends on the ground under your lot.
It needs one built for the lift, which isn’t always a bigger one in flow. A pump is sized by how far it lifts water, measured from where the level sits while pumping, plus the pressure the house needs, and it shouldn’t pull more than the well gives. With modest local yields, that usually means a moderate-flow pump, set from the water level measured in your well.
It isn’t the usual result here. Three quarters of the 364 local yield logs came in at 20 gallons a minute or less, and a quarter at 10 or less. That still supplies a household when the pump and tank are sized to the well, and the flow test at the end of drilling gives your own figure.
