ASHTABULA COUNTY, OHIO · 61 MIN FROM OUR CORTLAND OFFICE
EPA's map puts the Unionville Center town center inside a Lake County system, the Lake County East Water Subdistrict, which draws Lake Erie water for 40,656 people. Homes on its lines get their water report from the subdistrict. Wells nearby vary a good deal: the middle half of logs run from 41 to 85 feet deep.

WHAT WE DO IN UNIONVILLE CENTER
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.
Homes on the subdistrict's lines get water with chlorine, fluoride and an orthophosphate corrosion inhibitor added, and a CityLux system takes out the chlorine if it bothers you. Well owners get none of it, so for them treatment begins with a water test.
Well depths here are level with the county's: a median of 60 feet across 663 local logs, tenth of 19 county towns. Half of the 509 logs that record rock reach it within 27 feet, and a quarter go 50 feet or more.
Water rests a median 12 feet down in 621 logs, and 27 feet or less in three of four, a moderate lift. Flow, with a median of 7 gallons a minute, varies more, and the pump is sized to your own well's test.

The Lake County East Water Subdistrict is run by local government and serves 40,656 people through 11,352 connections. It takes water from Lake Erie through an intake and lists one treatment plant and 7 storage tanks. Coagulation, flocculation, settling and rapid sand filtration take out particles. Permanganate treats organics, and powdered activated carbon handles taste and odor. Chlorine gas after filtration disinfects the water, and the list also has fluoride, a pH adjustment and an orthophosphate inhibitor for corrosion control.
The subdistrict's annual report covers the water as delivered. A water test at your own tap adds what a system-wide report can't, such as lead from your own plumbing, and reverse osmosis at the kitchen sink is the usual answer if it finds any.
A quarter of the 663 local logs stop at 41 feet or less, and a quarter go to 85 or more. The median is 60, level with the county's median across 5,480 domestic logs. Rock varies as well, from 13 to 50 feet down in the middle half of 509 logs. The rock mapped at the town center is Ohio Shale.
Ohio's private-well rules set casing at 25 feet or more, and it goes down to rock where rock is deeper, so it can stop at that minimum on one lot and run much longer on another. Only the drilling itself settles which. Residential well drilling covers the work, and the cost page explains what goes into a quote.
WATER IN ASHTABULA COUNTY
In USGS samples from across Ashtabula County, taken 1982–2016, 89% of wells were hard or very hard, 56% carried iron above the staining line, 78% had manganese above 0.05 mg/L. The full record, and what it means for treatment, is on the Ashtabula County page; your own well gets its own test.
WHY UNIONVILLE CENTER 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 Cortland office (7115 Hoagland Blackstub Rd. Unit C, Cortland, OH 44410) is about 61 minutes and 51 miles by road from Unionville Center. Service calls for Unionville Center are scheduled from there.
Unionville Center and the municipalities around it: Madison, Madison Township, Geneva, Harpersfield Township, Geneva Township, Geneva-on-the-Lake, North Perry, Trumbull Township, Perry, Thompson Township. Beyond those, the rest of the 19 Ashtabula County communities on our service map, from the same office.
Ohio’s well-log database lists 663 domestic wells within 5 miles of Unionville Center: the median is 60 feet deep, and the middle half fall between 41 and 85 feet. The median well was logged at 7 gallons per minute. Drillers reached bedrock at a median of 27 feet. Your own well's depth depends on the ground under your lot.
EPA lists four rounds: 0.0021 mg/L for 2017, 0.0023 for 2018, 0.0022 for 2021, and a round recorded as zero for 2024. All four are under the 0.015 mg/L action level. They are 90th percentiles across homes sampled on a system serving 40,656 people, so one tap can differ; a certified-lab test gives yours.
The 621 local logs that record a yield have a median of 7 gallons a minute, but the range is wide: a quarter show 2 or less and a quarter 15 or more. The yield measured when your own well is test-pumped sets the pump and tank; on a slower well, the water standing in the bore and a larger pressure tank carry the busy moments.
