ERIE COUNTY, PENNSYLVANIA · 91 MIN FROM OUR GREENVILLE OFFICE
Rock lies deep around Lake City. In the 200 logs that record it, the median depth to bedrock is 61 feet, nearly matching the 62-foot median well, and a quarter didn't reach rock until 90 feet. For anyone drilling here, the length of casing is the number to plan around.

WHAT WE DO IN LAKE CITY
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.
The borough's water comes from two wells named Copes Vulcan, and EPA lists sequestration, which keeps iron and manganese dissolved, plus chlorination. Private wells are a separate matter: a test shows what yours carries before any equipment is chosen.
Girard Shale, siltstone and shale, is the rock mapped under the town, but a long stretch of ground often lies on top of it. Half the rock readings fall between 43 and 90 feet, so casing, which usually runs down to rock, is a big share of many wells.
Yields are middling: a median of 10 gallons a minute across 453 logs, a quarter at 5 or less, a quarter at 20 or more. Most wells suit a standard submersible and pressure tank, sized after a flow test on the finished well.

Casing usually runs from the surface down to rock, and here that is a long way. Only a quarter of the logs that record rock found it by 43 feet; another quarter went 90 feet or more before reaching it. By median well depth the town ranks 6th of 16 in Erie County, but casing can set one estimate apart from the next as much as total footage does.
Nearby logs give a first read, and rock is confirmed as the hole is drilled. Residential well drilling walks through drilling and casing, and the cost of a new well covers why its length shows up in the price. Wells here are served by the Chatfield crew from our Greenville office.
The borough's municipal water system serves 1,091 connections from two groundwater wells, Copes Vulcan #1 and #2, and lists one water plant. EPA lists sequestration for manganese and iron, chlorination after treatment and 4-log treatment of viruses, a disinfection level that kills nearly all of them. The EPA record we draw on has no lead 90th-percentile results for it, and homes on the line get their water report from the borough.
Private wells nearby are tested on their own. In Erie County's USGS record, 68% of 349 sampled wells were hard or very hard, with a median of 8.2 grains per gallon, so a LuxSoft water softener is often worth considering. A water test shows where your well sits.
WATER IN ERIE COUNTY
In USGS samples from across Erie County, taken 1927–2023, 68% of wells were hard or very hard, 33% carried iron above the staining line, 83% had manganese above 0.05 mg/L. The full record, and what it means for treatment, is on the Erie County page; your own well gets its own test.

“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.”

A LITTLE CLARITY
Our Greenville office (854 Mercer Rd., Greenville, PA 16125) is about 91 minutes and 65 miles by road from Lake City. Service calls for Lake City are scheduled from there.
Lake City and the municipalities around it: Girard, Girard Township, Platea, Fairview Township, Springfield Township, Cranesville, Albion, Franklin Township, Elk Creek Township. Beyond those, the rest of the 16 Erie County communities on our service map, from the same office.
Pennsylvania’s groundwater database (PaGWIS) lists 515 domestic wells within 5 miles of Lake City: the median is 62 feet deep, and the middle half fall between 42 and 88 feet. The median well was logged at 10 gallons per minute. Drillers reached bedrock at a median of 61 feet. Your own well's depth depends on the ground under your lot.
As much as it takes to reach rock, since casing usually runs down to it. Around Lake City, the 200 logs that record rock range from 43 feet or less in the shallowest quarter to 90 or more in the deepest. The driller sets the final length from what the hole shows, so it is confirmed during drilling.
EPA lists sequestration on the borough system for manganese and iron. Sequestration generally means binding those metals so they stay dissolved rather than filtering them out. It is part of the borough's treatment, so it only applies to homes on the borough line. On a private well, a FerronX Iron System removes iron and manganese once a test shows the levels.
