What Makes Brooklyn Park's Water Unique?
Local geology and source profile
Brooklyn Park, Maryland, in Anne Arundel County — an Anne Arundel County community adjacent to Glen Burnie and Baltimore in central Maryland — receives its water from Baltimore City Water or the Anne Arundel County Bureau of Utilities, drawing from Loch Raven Reservoir (Anne Arundel County) through the Baltimore metro distribution.
The hard 193 mg/L hardness and TDS of 506.1 mg/L reflect the central Maryland Baltimore Loch Raven Reservoir supply's hard Maryland Piedmont calcareous character — harder than typical New England gneiss supplies due to the Cambrian Cockeysville Marble dissolution in the Gunpowder Falls watershed. The Loch Raven watershed at Anne Arundel County drains the Maryland Piedmont — Precambrian Baltimore Gneiss (insoluble), Precambrian Cockeysville Marble (calcareous — primary hardness contributor), Cambrian Setters Quartzite (insoluble), and Ordovician calcareous formations.
At 193 mg/L, Brooklyn Park's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 10.6 ppt warrants a certified reverse osmosis drinking water filter — Fort Meade (Anne Arundel County — AFFF) and Martin State Airport (Baltimore County — AFFF) contribute to Brooklyn Park's elevated readings.
