A Well, Three Springs and Greensand
Sandy Lake Borough serves 357 connections from four sources EPA lists as Well #1 (the Patton Well) and Springs 1, 2 and 3, with one plant, Patton Rd. The steps it records aim mostly at iron and manganese. A pH adjustment and chlorine come ahead of treatment, then permanganate, greensand filtration and sequestration, and then chlorine again, with 4-log treatment of viruses, which kills nearly all viruses. It also buys water from Stoneboro Water Works, which EPA notes is treated by the seller. The record we draw on has no lead rounds, and homes on the line get their water report from the borough.
A private well can take the same metals out at the house with a FerronX iron removal system, once a water test shows the levels.
Strong Flow Around Sandy Lake
Yield is seldom the constraint in these logs. Across 496 of them the median is 25 gallons a minute, and only a quarter show 15 or less. A standard submersible pump sized to the house seldom outruns wells like these, and a constant-pressure upgrade is usually an option.
Depth and casing vary more. A quarter of the 611 logs went to 115 feet or more, and rock came up at 22 feet or less in a quarter of logs and 65 or more in another, so casing, which usually runs down to rock, differs from lot to lot. Residential well drilling covers the process, with PA DEP permit assistance, and nearby Stoneboro has its own well picture.
