A water powered lime doser was installed by the Indiana County Conservation District at the Indiana County Waterworks Conservation Area, on Waterworks Road. A predetermined amount of hydrated lime is dumped into the R & P Lucerne 3A mine discharge to neutralize the acidic water. Raising the pH of the water results in the precipitation of iron.
There is a settling pond for collection of undissolved lime and iron. Treated water is discharged to Twolick Creek. Reports, maps, photos, and water sampling results have been posted on the Datashed website at www.datashed.org.
