What Makes Glasgow's Water Unique?
Local geology and source profile
Glasgow, Delaware, in New Castle County — a New Castle County community adjacent to Newark and Brookside in northern Delaware — receives its water from the Artesian Water Company of Delaware or United Water Delaware, drawing from the Christina River and Coastal Plain groundwater (New Castle County) through the northern Delaware distribution.
The moderately hard 151.5 mg/L hardness and TDS of 468.6 mg/L (TDS elevated relative to hardness — reflecting the Coastal Plain aquifer's concentrated mineral content from long subsurface residence time) are harder than the Piedmont position Brookside (101 mg/L) — reflecting Glasgow's more southerly Coastal Plain aquifer position where the Cretaceous Potomac Formation and Pleistocene Columbia Formation provide greater calcareous mineral dissolution. The New Castle County Coastal Plain aquifer — Cretaceous Potomac Formation (slightly calcareous — primary hardness contributor), Pleistocene Columbia Formation (calcareous), and Quaternary alluvium (slightly calcareous).
At 151.5 mg/L, Glasgow's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 8.8 ppt warrants a certified reverse osmosis drinking water filter — Dover Air Force Base (Kent County — AFFF) and the northern Delaware Wilmington industrial PFAS corridor contribute to Glasgow's elevated readings.
Geology & Source: Glasgow in New Castle County draws from the Artesian Water Company on the Christina River and Coastal Plain groundwater (New Castle County, northern Delaware) — the Coastal Plain aquifer is developed in Cretaceous Potomac Formation (slightly calcareous) and Pleistocene Columbia Formation (calcareous) — Delaware New Castle County Coastal Plain Cretaceous-Pleistocene calcareous aquifer produces moderately hard water at 151.5 mg/L with TDS 468.6 mg/L.
