Kirkland Lake at 210 mg/L is hard enough to scale kettles, but most residents solve taste and lead at the tap first. Carbon filtration + test strips; whole-house softener only if repeat hardness readings justify it.

Kirkland Lake's drinking water earns Grade B (Good). Hardness is 210 mg/L (very hard), and pH is 7.8 against Health Canada's 6.5–8.5 guideline.
Lead at 0.2 μg/L is below the 5 μg/L maximum, and fluoride is 0.6 mg/L against a guideline of ≤ 1.5 mg/L.
