Premium filter strongly recommended
Your water has contaminants that require stronger filtration (heavy metals, PFAS, or limits exceeded). Reverse osmosis is the recommended tier.
See recommended water filters →What is in the water
Trihalomethanes (THMs)
DetectedDisinfection byproducts formed when chlorine reacts with organic matter. Long-term exposure linked to cancer risk.
Reported: ~25 ug/L
Chlorine
Within limitsAdded to disinfect water. Generally safe at treatment levels but reacts with organic matter to form disinfection byproducts.
Reported: typical residual maintained across the regional network
Lead
DetectedA heavy metal that leaches from older plumbing. No safe exposure level for children. Linked to developmental and cognitive harm.
Reported: older Kitchener housing stock remains the main point-of-use concern

Data from the Region of Waterloo Water Quality (2024). Last reviewed 2026-05-25.
Lead risk is concentrated in older private plumbing and legacy service lines rather than treated water leaving the plant.
Note: Contaminant levels vary by address (older plumbing can leach lead even when the source water does not), sampling location, and time of year. The figures above reflect utility-wide averages from the most recent public report. If you have specific health concerns, request a full report from your utility or test your own tap water.
