North Lima Wells and the County Median
Wells near North Lima track Mahoning County closely. The median across 2,664 logs within five miles equals the county's median for domestic wells, 120 feet, and the quarter marks line up too: 86 feet at the shallow end against the county's 85, and 165 at the deep end, matching it. The town ranks 7th of 21 in the county by median depth.
Most of a typical well is rock: the top of rock sits a median 35 feet down, and the median well goes on to 120 feet. The rock mapped at the town center is the Allegheny and Pottsville Groups, layered sandstone, limestone, siltstone and shale of Pennsylvanian age, and a hole through layers like those picks up water where it crosses a productive bed or fracture. Well drilling explains the process. What the water carries is a question for a test, covered on the treatment page.
Setting a Pump in North Lima's Deep Wells
A deep well doesn't mean the water sits at the bottom of it. In the logs around North Lima, three in four record a static level of 43 feet or less, and one in four 15 feet or less. The hole below that stands full.
That shapes the pump job. A submersible pump hangs below the static level with room for the drop that pumping causes, and usually well off the bottom, so the drop pipe and wire run to the pump setting, not to the full depth of the well. The lift it works against runs from the pumping level up to the house, plus the pressure the house needs. When a pump is pulled for repair, the setting can be checked against how the water level behaves now.
