MERCER COUNTY, PENNSYLVANIA · 20 MIN FROM OUR GREENVILLE OFFICE
Jamestown is the borough at the north end of Pymatuning, where the Shenango leaves the lake, with Greene, West Salem, and Pymatuning townships’ farms and lake homes around it. Most homes outside the borough are on private wells, and their owners ask us what it takes to look after one. Chatfield is a few minutes away at our Greenville office.

WHAT WE DO IN JAMESTOWN
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 Jamestown and the lake carry the county’s iron and hardness, with sulfur smell and manganese in some. A water test tells us which, and the equipment follows from it. Where all three turn up, the FerronX comes first, a carbon filter second, and the softener last.
New wells for homes, farms, and lake properties in Greene, West Salem, and Pymatuning townships, drilled with air rotary or cable tool as the ground calls for. PA DEP permitting is handled, the casing is set to seal out surface water, the pump goes in, and water flow is tested before the rig leaves.
Jamestown wells get pump, switch, and tank service with one of the shortest drives on our map. 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.

Bedrock is seldom far down here. The 356 logs within 5 miles that note it put rock at a median 18 feet, and a quarter found it at 12 or less. Under the town, the mapped rock is the Late Devonian Berea Sandstone through Venango Formation, a sequence of shale, sandstone and siltstone.
For a new well, that usually leaves only a thin layer of loose ground for the casing to cross before it reaches rock, and the rest of the hole is open rock. Depth sits mid-county: by median, Jamestown ranks 9th of 15 Mercer County towns, and a quarter of the logged wells reached 120 feet or more. Short casing and moderate depth both bear on the cost of drilling a new well, and drilling a home well covers how the hole is finished.
Yield is the less predictable number. Its median across 608 logs is 20 gallons a minute, but the middle half stretches from 12 to 37, so the flow from one lot to the next is hard to call in advance. That is why the pump is chosen after the flow test, not before, and why a neighbor’s pump size is a poor guide to yours.
A well near the low end gets a smaller submersible and more tank capacity to cover heavy use; one near the high end can carry a larger pump or a constant-pressure setup. The borough’s own supply is groundwater as well, from three wells, and the authority sends its own water report to homes on the line. Water treatment in Jamestown covers what that system does.
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 JAMESTOWN 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
The wellhead and cap, the switch settings, the pressure tank’s air charge, and the water itself, tested for bacteria and the minerals. Our annual well checkup does all four and writes the readings down so the next year has something to compare against.
Yes. Lake-property wells with the casing set to seal out surface water, 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 20 minutes and 12 miles by road from Jamestown. Service calls for Jamestown are scheduled from there.

Pennsylvania’s groundwater database (PaGWIS) lists 679 domestic wells within 5 miles of Jamestown: the median is 93 feet deep, and the middle half fall between 70 and 120 feet. The median well was logged at 20 gallons per minute. Drillers reached bedrock at a median of 18 feet. Your own well's depth depends on the ground under your lot.
It can. With rock this close to the surface, there is little soil to filter water soaking in around the wellhead. That puts weight on a sound casing seal, a watertight cap and ground that slopes away from the well. A yearly bacteria test through a certified lab is the simple check that those are holding.
It can be either. A quarter of the logged wells here yield 12 gallons a minute or less, and on a well like that a pump set too large can draw the water down and lose pressure mid-shower. A worn pump, a failing switch and a waterlogged tank cause the same symptom, so each gets tested before anything is replaced.
