Woodland Park's tap water comes through the Passaic Valley Water Commission and is delivered by the Borough of Woodland Park. The borough's 2022 water quality report gives a computed median of 146 mg/L as CaCO₃, within a range of 118 to 174 mg/L. That is hard water by USGS classes, so expect limescale on kettles and water heaters.
USGS classes: soft 0–60, moderately hard 61–120, hard 121–180, very hard >180 mg/L.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
