ASHTABULA COUNTY, OHIO · 39 MIN FROM OUR CORTLAND OFFICE
Jefferson is the seat of Ashtabula County, a village on the state route with farm townships in every direction. In the village homes are on public water; a few minutes out, they are on private wells, and pump service and new wells are the reasons Jefferson calls us. The crew comes from our Cortland office.

WHAT WE DO IN JEFFERSON
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.
Jefferson-area well water tends to carry iron and hardness, sometimes with a sulfur smell, and the fix depends on the mix. A water test tells us what is in the water and at what level. Then a FerronX, a softener, or a carbon filter goes in, with the iron handled ahead of the rest.
Jefferson-area homeowners often need a new well, and this is the county where we drill a lot of them, for homes and farms in Jefferson, Denmark, Lenox, Dorset, and the townships between them. We match air rotary or cable tool to the ground, handle the permit, and test water flow before the rig leaves.
Well pump service is the most common Jefferson call. For low pressure, a pump that will not shut off, or no water, the crew diagnoses the pump, the switch, and the tank together and replaces the part that failed, with the common sizes on the truck.

Wells near Jefferson are short for the county, 17th of 19 Ashtabula County towns by median depth. Of the 679 logs within five miles, only one in four reaches 60 feet or more, which is the depth of the county's median domestic well.
Short doesn't mean the wells stop in loose ground. A well at the shallow-quarter mark, 45 feet, still goes past the deep-quarter mark for top of rock, 30 feet, so most logged wells here finish in rock. The rock mapped at the town center is Ohio Shale. For a new well, that means casing through the upper ground, usually sealed into the rock, and less drilled footage than a deeper county well would need. The cost page explains how depth and casing figure into a quote.
Water rises close to the surface in wells near Jefferson: three logs in four put the static level at 12 feet or less, and one in four at 5 or less. That is a lot of water standing in a short hole, but it says nothing about how fast the hole refills. Flow is modest, and even the best quarter of logs starts at 7 gallons per minute.
On a well like that, the pressure side of the system carries much of the load. A pressure tank holding more usable water lets the pump run longer and start less often, and a pressure switch set to suit the pump and tank keeps cycling in check. The pump itself is chosen for the flow the well can sustain. Water quality is a separate test, covered on the treatment page.
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.

Rated 4.7 on Google across 104 reviews. Here is what working with us looks like, in a customer’s words.
“I had the pleasure of having Sam and Hunter for the installation of my new water softener, and I couldn’t be more impressed. The system is working great, and I can already notice a difference in the water quality.”
NEARBY
We send the same crews to each of these towns. If you’re between towns, pick the closest one; the service doesn’t change.
A LITTLE CLARITY
Yes. Residential and agricultural wells in Jefferson and the surrounding townships, with the method matched to the ground on your property. We handle the permit paperwork, set the casing and pump, and test the flow before we are done.
Jefferson is a short drive from our Cortland office. Call the office and describe what the water is doing; no-water calls go to the front of the line, and the truck carries the common pump and tank sizes so most repairs finish in one visit.
Yes. Iron and manganese are treated with the FerronX Iron System at the point of entry, ahead of a softener if the test shows hardness too. The test comes first, because iron equipment sized to a guess does not last.
Our Cortland office (7115 Hoagland Blackstub Rd. Unit C, Cortland, OH 44410) is about 39 minutes and 31 miles by road from Jefferson. Service calls for Jefferson are scheduled from there.

Ohio’s well-log database lists 679 domestic wells within 5 miles of Jefferson: the median is 53 feet deep, and the middle half fall between 45 and 60 feet. The median well was logged at 4 gallons per minute. Drillers reached bedrock at a median of 22 feet. Your own well's depth depends on the ground under your lot.
The flow, the pump, the pressure switch and tank, and the water itself. A well inspection measures what the well gives today, and the local logs make a fair yardstick: one well in four around here gives 2 gallons per minute or less. A water test covers the rest, so you know what the house needs before it is yours.
Sometimes not. An open hose can draw more than a well giving 4 gallons per minute, the local median, and a long run pulls the water down toward the pump. Watering in shorter spells lets the well recover between them. If outdoor use matters to you, say so before the pump and tank are sized, so the system is built around it.
