Reverse osmosis in Bowmanville

Clarington has three municipal supplies. Bowmanville has its own Lake Ontario plant, with an intake 1,260 m into the lake. Newcastle and Newtonville have their own lake plant, which adds UV disinfection. Courtice is on the Oshawa/Whitby/Ajax system, and Orono runs on two municipal wells.

• Chlorine: free chlorine in the distribution system ranged 0.32 to 3.70 mg/L in Bowmanville and 0.44 to 3.60 mg/L in Newcastle in 2025. That's what keeps the water safe in the pipes, and what most people taste.
• Fluoride: not added (0.06 to 0.09 mg/L in Bowmanville and 0.06 to 0.1 mg/L in Newcastle in 2025). Unlike the lakeshore towns, fluoride isn't added here.
• Sodium: 13.8 to 17.3 mg/L in Bowmanville and 15.5 to 40 mg/L in Newcastle.
• Lead: Bowmanville's 196 plumbing samples ranged from non-detect to 0.0038 mg/L in 2025, under the 0.01 mg/L limit.
