Lodi Water Hardness & Quality Report (2026)

Lodi Borough Department of Public Works operates the municipal water utility serving Lodi Borough in Bergen County, New Jersey, a densely populated area near the Hackensack River. Water is sourced from local groundwater wells tapping into the unconfined aquifers of the Coastal Plain, with no named reservoirs or rivers directly used. Treatment occurs at the borough's wellhead facilities, including disinfection and basic filtration; no softening is applied as the minerals pose no health risks.

The supply originates from the local groundwater recharge area within the Hackensack Meadowlands watershed, underlain by Cenozoic Coastal Plain sediments. Key formations include the Miocene Kirkwood–Cape May aquifer system, featuring permeable sands and gravels with calcareous shells that dissolve calcium carbonate and magnesium into the groundwater through prolonged contact. This geology results in naturally mineralized, very hard groundwater with high total dissolved solids — around 510 mg/L — typical of New Jersey's glaciofluvial and marine deposits.

Very hard water promotes significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. White mineral deposits appear on fixtures and glassware, while soap scum forms in showers and baths. A water softener is strongly recommended; regular vinegar descaling and low-flow aerators also help, but professional treatment prevents costly appliance and plumbing repairs. The utility complies with EPA lead and copper standards showing non-detects or below action levels in tap sampling; pH is typically neutral to slightly alkaline. Treatment includes aeration at wells, chlorination, and corrosion control as needed.
