Holland Water Hardness & Quality Report (2026)

Holland Board of Public Works (BPW) supplies water to the city of Holland and surrounding areas in Ottawa County, Michigan, primarily from groundwater wells tapping into local aquifers. The utility operates the Holland Water Treatment Plant, which processes water from multiple wells in the glacial drift aquifer. Service covers approximately 35,000 residents in the city and nearby townships, with no surface water sources reported in available quality documents. The Lake Michigan basin provides the broader recharge area for this groundwater supply.

The groundwater recharge area is part of the broader Lake Michigan basin, with precipitation percolating through glacial till and outwash deposits. Underlying Paleozoic bedrock includes Devonian-age dolomite and limestone formations such as the Rogers City Limestone, along with the Antrim Shale and Bell Shale groups of the Michigan Basin. These carbonate-rich formations dissolve naturally, imparting a hard character to the supply without aggressive treatment beyond standard filtration and disinfection.

At hard levels, scale accumulation affects water heaters, dishwashers, and washing machines most severely, reducing efficiency and lifespan. Fixtures like faucets and showerheads may clog, leading to higher detergent use and drier skin and hair. Regular maintenance includes deliming appliances annually; a water softener is strongly recommended for households to prevent spotting on glassware and extend plumbing life. Holland BPW water quality reports confirm compliance with EPA standards for pH, lead, and copper, with no PFAS detections noted in the 2021 CCR and treatment involving aeration, filtration, chlorination, and fluoride addition.
