Erie County's town well logs show modest yields: medians of 5 to 10 gallons a minute at all 16 towns on our map. Around Girard and Lake City, bedrock also sits well down, at a median 53 and 61 feet.
Yields of 5 to 10 gallons a minute
North East and Wesleyville have the lowest median yield in the logs, 5 gallons a minute. Albion, Cranesville and McKean log 6, Platea 7, and Erie and Waterford 8. Corry, Edinboro, Elgin, Fairview, Girard, Lake City, Mill Village and Wattsburg reach 10. Each figure is a median across the logs within 5 miles of a town center, so one well can do better or worse.
On a slower well, the pump and pressure tank have to be matched to what the well gives, and Chatfield designs the pump system around the yield. A constant-pressure upgrade evens out the pressure at the tap. If a well that used to keep up starts running short, pump diagnostics and repair come before any talk of a new well, and well cleaning can be part of the answer.
Where bedrock sits deepest
Median well depths in the logs run from 50 feet around North East to 86 around Elgin, and the USGS county record of 1,755 wells has a median of 60 feet, with a middle half of 45 to 78. Depth to bedrock splits the towns. Around North East and Wesleyville the logs reach rock at a median 18 and 19 feet; around Girard and Lake City, at 53 and 61, against median well depths there of 60 and 62.
Girard Shale is mapped at the Fairview, Girard and Lake City town centers, and Northeast Shale at Erie, North East and Wesleyville. The Venango Formation is mapped at Corry, Edinboro, Elgin and Mill Village, and the Chadakoin Formation at the other six. With that much variation, the logs nearest a lot are worth reading before a new well goes in.
Lake Erie intakes and well-fed systems
Thirteen of the 16 towns sit inside a public system on EPA's map. The Erie City Water Authority, by far the largest, draws from two Lake Erie intakes and Presque Isle Bay and covers three of those towns, Erie and Wesleyville among them. North East Borough takes surface water from three reservoirs, Videtto Springs and Lake Erie. The rest pump groundwater. Albion draws from eight active wells, Corry and the Fairview Township authority's District 3 from seven each, and Waterford from five. Edinboro and Girard use three, Lake City two and Wattsburg one. Cranesville buys its water from Albion.
Elgin, Mill Village and Platea have no system on that map, which doesn't mean no home there is connected; a home on a public line gets its report from the utility. The Erie County treatment page covers what the systems do to their water.
