Water Filtration in Peel Region

Brampton, Mississauga & Bolton

7–8 gpg · Lake Ontario · Chlorinated · Moderately hard

How hard is Brampton and Mississauga water? Moderately hard — about 7–8 grains per gallon on the South Peel Lake Ontario system, and Bolton runs the same supply. That's enough hardness for a softener to protect your plumbing and appliances, and a reverse-osmosis drinking-water system removes the chlorine taste.

Caledon

18–28 gpg · Groundwater · Chlorinated + greensand filtration · Extremely hard

Why is Caledon water so much harder than the rest of Peel? Because Caledon is on municipal groundwater wells, not the lake — and groundwater runs 18–28 grains per gallon here, very hard, with enough iron that the wells use greensand treatment. A water softener is the core system in Caledon, often paired with iron filtration.
