WHAT WE DO IN TOWNVILLE
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.
Bacteria isn’t part of Crawford County’s USGS record, so it’s worth adding to any test on a Townville well, especially after pump work or on a new well. Where a test finds it, Luminor UV treats the water after filtration.
Depths are mid-range for Crawford County: half the 184 depth logs fall between 60 and 100 feet, and the area shares 8th place among 16 towns by median. Where rock is deep, casing usually goes deep with it, so on some lots a good part of the hole is cased.
Yields are fairly even: a median of 15 gallons per minute, with the middle half of 181 logs between 10 and 20. A submersible pump and pressure tank matched to a flow test are the usual setup, with a booster pump for homes that need more pressure at the far taps.

Near Townville, some wells go a long way before reaching rock. A quarter of the 137 logs that record rock reached it by 21 feet, the median is 34, and a quarter went 63 feet or more. The casing usually follows the hole down to rock, sealing out the looser ground above, so on a lot at the deep end it’s a long run.
Your own depth to rock is found at the rig, and the log for your finished well records it, a number worth keeping with the house papers. Residential well drilling covers the job, and the new well cost page explains how depth and casing move the price.
A well in rock takes in water where the hole crosses fractures, and the Townville logs suggest those give fairly even results. Of 181 logs within 5 miles, the median yield is 15 gallons per minute, a quarter came in at 10 or less, and a quarter at 20 or more. Depths are similarly contained, with half of 184 logs between 60 and 100 feet.
Those are area figures, and the mapped rock is a guide rather than a measurement in each well, so a single hole can still land outside the ranges. Chatfield drills by air rotary and cable tool, and well drilling explains how ground conditions shape the choice of method. Once the yield is known, a submersible pump is sized to it and to the household.
WATER IN CRAWFORD COUNTY
In USGS samples from across Crawford County, taken 1928–2023, 77% of wells were hard or very hard, 35% carried iron above the staining line, 45% had manganese above 0.05 mg/L. The full record, and what it means for treatment, is on the Crawford County page; your own well gets its own test.
WHY TOWNVILLE 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 69 minutes and 43 miles by road from Townville. Service calls for Townville are scheduled from there.
Townville and the municipalities around it: Steuben Township, Troy Township, Randolph Township, Athens Township, Richmond Township, Centerville, Plum Township, Hydetown, Blooming Valley. Beyond those, the rest of the 16 Crawford County communities on our service map, from the same office.
Pennsylvania’s groundwater database (PaGWIS) lists 184 domestic wells within 5 miles of Townville: the median is 80 feet deep, and the middle half fall between 60 and 100 feet. The median well was logged at 15 gallons per minute. Drillers reached bedrock at a median of 34 feet. Your own well's depth depends on the ground under your lot.
It’s the rock’s age. The Cuyahoga Group mapped at the town center dates from the Mississippian period and is made up of siltstone, shale and sandstone. The age doesn’t tell you what a well will yield; the logs are the better guide there, and around here the median of 181 logged yields is 15 gallons per minute.
Sometimes. Over the years, buildup inside a well can cut its flow, and a well cleaning loosens it, pumps it out and disinfects the well. A well inspection first measures the flow and checks the pump, tank and wellhead. If a well gives much less than it used to, that check comes first.
