What's in Uxbridge's drinking water?
Uxbridge's urban area is supplied by three municipal wells, 58 to 77 metres deep, drilled into the Oak Ridges Moraine. The Region adds sodium silicate for iron and uses chlorine, plus UV disinfection at two of the wells.
- Chlorine: free chlorine in the distribution system ranged 0.69 to 1.84 mg/L in 2025. That's what keeps the water safe in the pipes, and what most people taste.
- Fluoride: not added (0.06 to 0.11 mg/L in 2025). Unlike the lakeshore towns, fluoride isn't added here.
- Sodium: 5.76 to 12.8 mg/L.
- Lead: One distribution sample in April 2025 was above half the limit but below it; there were no exceedances.

Why reverse osmosis
A reverse osmosis system under your kitchen sink removes chlorine taste, most dissolved solids, lead, fluoride and sodium from drinking and cooking water. It's bottled-quality water from its own faucet, without carrying cases home.
- Better-tasting water, coffee, tea and ice
- Removes most dissolved solids, lead and fluoride
- Fits under the sink with its own faucet
- Usually costs less than buying bottled water
