Hard Water
Scale buildup, soap that won't lather, and spotted dishes are classic signs of New Jersey's naturally hard water in many areas.
Short answer: Hard water comes from dissolved calcium and magnesium, common in many New Jersey groundwater areas. It's a nuisance, not a health risk, and is addressed with a water softener matched to your hardness level.
Common signs
- White or chalky scale on faucets, showerheads, and coffee makers
- Soap and shampoo that don't lather well
- Spotting on dishes and glassware
- Dry skin or dull-feeling hair after showering
- Reduced water heater efficiency over time from scale buildup
Step-by-step
- Check your CCR for a hardness value, if reported, or have your water tested for hardness (measured in grains per gallon or mg/L).
- Compare your hardness level to typical softener sizing guidance.
- Choose a softener sized to your household's water use and hardness level (see Water Softeners).
- Maintain the softener's salt level and resin bed per manufacturer instructions.
Common mistakes
- Buying an undersized softener for household size and hardness level
- Confusing hardness with a health or safety issue
- Skipping regular salt refills, which reduces softener effectiveness
Official sources
- Your utility's current CCR

Is hard water unsafe to drink?
No. Hardness is an aesthetic and household-maintenance issue, not a recognized health risk at typical levels.
