What Makes Hanover's Water Unique?
Local geology and source profile
Hanover, Pennsylvania, in York County — a York County city adjacent to McSherrystown and Spring Grove in south-central Pennsylvania near the Maryland border — receives its municipal water from the Hanover Water Division, drawing from Conewago Creek (York County) through the south Pennsylvania water treatment system.
The very hard 204 mg/L hardness and elevated TDS of 522.8 mg/L reflect the south Pennsylvania Conewago Creek watershed's intense Cambrian-Ordovician limestone character — among the hardest surface water supplies in Pennsylvania. The Conewago Creek (York County) drains the South Mountain Anticlinorium — Cambrian Conestoga Formation (very high purity calcareous limestone — primary hardness contributor at south Pennsylvania), Ordovician Jacksonburg Limestone (calcareous), and Cambrian Chickies Formation (calcareous quartzite). The concentrated Cambrian Conestoga limestone exposure in the Conewago watershed produces the very hard south Pennsylvania supply.
At 204 mg/L with TDS 523, Hanover's water is very hard. A water softener is strongly recommended. Scale builds rapidly on all surfaces, appliance lifespans are significantly shortened, and water heaters require annual descaling without softening. The PFAS level of 10.6 ppt warrants a certified reverse osmosis drinking water filter — Naval Air Station Patuxent River proximity (Maryland, AFFF — across the border), Aberdeen Proving Ground upstream PFAS migration, and the south Pennsylvania York County industrial corridor contribute to Hanover's very elevated readings.
