Wells, rock and hard water
A Delaware River Basin Commission notice says two of the authority's wells are in Cambrian Leithsville and Richland formations and two are in Precambrian gneiss. The 1999 Western Berks plan describes most of Robesonia and Womelsdorf as underlain by Cambrian quartzite and dolomite, with gneiss in the hills south of Robesonia.
Carbonate rock usually means hard water. Water moving through limestone and dolomite picks up calcium and magnesium. Hard water →
Gneiss and quartzite can mean soft, acidic water. Private wells in the hills can be the opposite. Acidic water →
Older homes. Census data show 33% of Robesonia's homes and 20% of Womelsdorf's were built in 1939 or earlier.
