Orchards Water Hardness & Quality Report (2026)

Orchards, Washington, is served by the Orchards Water Association or Clark Public Utilities in Clark County, providing water to this unincorporated community near Vancouver. Multiple groundwater wells tap local aquifers in the Vancouver Lake Lowlands; no major surface reservoirs or rivers serve as primary sources. Treatment involves chlorination for disinfection at wellhead facilities, with no large centralized plants noted. The service area covers residential neighborhoods in Orchards, focusing on domestic and irrigation needs throughout the community.

The supply originates in the Lower Columbia River watershed, drawing from unconsolidated glacial outwash and alluvial aquifers beneath the Orchards area. These overlie Pleistocene glacial deposits and Miocene Columbia River Basalts, with sands and gravels acting as the primary aquifer. Calcium- and magnesium-bearing minerals from volcaniclastics and sedimentary fragments dissolve during groundwater percolation, shaped further by regional basalt weathering and flood-deposited limestones from the Fraser Glaciation and Missoula Floods, yielding a moderately mineralised supply with balanced mineral content.

At moderately hard levels, scale buildup occurs gradually on fixtures and in pipes, most affecting water heaters, dishwashers, and washing machines by reducing efficiency and lifespan. Soap lathering is somewhat reduced, leading to higher detergent use. Maintenance includes regular vinegar descaling of faucets and showerheads, annual water heater flushing, and installing anode rods. A water softener is recommended for households with frequent scale issues. Water quality reports indicate pH of 7.2–7.8, full compliance with EPA lead and copper rules, no PFAS detections above advisory levels, and groundwater disinfected via sodium hypochlorite with orthophosphate corrosion control.
