LiveSmart water-quality summary

Published water-quality measurements.

This page includes the available dated public measurements below. Hardness is shown in grains per gallon where the source provides enough information to report or convert it. Parameters not present in the published source should not be interpreted as zero.

Hardness in grains per gallon.

Conversions of the published hardness results retained on this page. Each row keeps its sample or supply context; these are not additional tests or a single current community average.

A dash means the source uses one merged result cell rather than separate minimum, maximum and average figures. Numbers attached to parameter names refer to footnotes in the source. The tables include reported treatment-performance measures as well as concentrations. Fluoridation resumed June 30, 2025; the annual fluoride statistics span that change.

A LiveSmart recommendation for every home

Better drinking water starts with HydroPure RO.

LiveSmart recommends a HydroPure reverse-osmosis drinking-water system in every home for cleaner, better-tasting water used for drinking, coffee, cooking and ice. Municipal treatment protects the public supply; point-of-use RO provides an additional treatment step at the kitchen tap. Reduction claims depend on the verified system configuration, certification and proper maintenance.

HydroPure RO

Recommended for every home. Final configuration is selected for the household and verified against the water at the tap.

Explore HydroPure RO ↗

Whole-home treatment

When testing confirms hardness, disinfectant taste or odour, iron, manganese, sediment or microbiological concerns, LiveSmart can add the appropriate SoftFlow, CarbonShield, IronShield or UV Guard treatment.

Explore treatment options ↗

Built for the home

Community results are a starting point. Household demand, flow, available space and plumbing are checked before equipment is sized and built.
