What Makes Niagara Falls's Water Unique?
Local geology and source profile
Niagara Falls, New York, in Niagara County on the Niagara River at the Canadian border — home of one of the world's most famous natural landmarks, Niagara Falls (the most powerful waterfall in North America by volume), historically one of the first hydroelectric power centers in the world, and a diverse city with a complex industrial and tourism heritage — draws its municipal water supply from the Niagara River (Lake Erie outflow) via the City of Niagara Falls Water Board. Water hardness in Niagara Falls measures 161.5 mg/L — classified as hard.
Niagara Falls' hard supply reflects the Niagara River's Lake Erie calcareous Great Lakes Basin geology. The Niagara River is the outlet of Lake Erie — receiving tributary drainage from the Lake Erie basin calcareous calcareous till plain (Ohio, Pennsylvania, and Ontario calcareous glacial till recharge) and the Niagara Escarpment (Silurian Lockport Dolomite — the very calcareous dolomite caprock of the Niagara Escarpment that creates the falls through differential erosion of the softer Rochester Shale below). The Lockport Dolomite's calcareous dissolution in the Niagara Peninsula groundwater recharge contributes to Lake Erie and Niagara River hardness, producing the hard 161.5 mg/L at Niagara Falls.
At 161.5 mg/L, Niagara Falls residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. City of Niagara Falls Water Board consistently delivers water meeting all New York State DOH and EPA Safe Drinking Water Act requirements.
Geology & Source: Lake supply from Lake Erie and Lake Ontario via the City of Niagara Falls Water Board — the Niagara County Niagara River corridor (Silurian Lockport Dolomite and the Niagara Escarpment calcareous dolomite — the geology responsible for Niagara Falls itself); hard supply at 161.5 mg/L in Niagara County.
