Lebanon Water Hardness & Quality Report (2026)

The City of Lebanon Water Department supplies water to about 10,050 residents in Lebanon, New Hampshire. This utility draws its water from protected groundwater wells within the Upper Connecticut River Valley watershed. Treatment processes are managed at the local water treatment plant. While no specific reservoirs or river intakes are mentioned, the supply relies on these aquifers, with recharge coming from forested uplands and glacial deposits. The City of Lebanon Water Department ensures compliance with all EPA standards, offering 24/7 emergency support at 603-448-1212.

The region's geology is characterized by Valley and Ridge province bedrock, including metamorphic and igneous formations like the Devonian Littleton Formation schists. These types of bedrock, prevalent in the Connecticut River Valley aquifer system, limit the leaching of minerals. The shallow, unconfined aquifer, found in alluvial sands and gravels, contributes to a very soft water profile. This softness stems from the absence of extensive carbonate rocks, resulting in water with minimal dissolved solids and a character resistant to scaling.

Because the water is naturally very soft, you'll notice soap lathers easily with less detergent, and fixtures tend to stay cleaner. This low mineral content spares appliances like water heaters, dishwashers, and coffee makers from damaging scale buildup, potentially extending their lifespan with less maintenance. While a water softener isn't necessary, homeowners might want to monitor for potential corrosion, a common issue with soft water supplies. Recent reports confirm the water meets all EPA guidelines, with treatment focused on turbidity and disinfection.
