Shorelands System water quality
Moderately Hard2 municipalities · Monmouth
Shorelands System reports water hardness of 4.3 grains per gallon — 74 mg/L as calcium carbonate, moderately hard on the USGS scale. Because the reading is taken on finished water leaving treatment, it is the figure for all 2 towns on this system rather than for any one of them.

Questions people ask
- How hard is Shorelands System water?
- Shorelands System reports hardness of 4.3 grains per gallon (74 mg/L as calcium carbonate), which the USGS scale classifies as moderately hard. The figure is a system-wide reading and applies to every municipality on the system.
- Which towns are served by Shorelands System?
- 2 municipalities on file are served by Shorelands System, across Monmouth County: Hazlet, Holmdel.
- Why do towns on Shorelands System publish the same hardness number?
- Hardness is measured at the treatment plant and at entry points to distribution, not street by street. Every town buying finished water from Shorelands System therefore reports the same value.
- How much sodium is in Shorelands System water?
- Shorelands System reports sodium at 4.1 to 69.9 ppm (avg ~69.9 max). That matters for anyone on a sodium-restricted diet, and it is also what rises if an ion-exchange softener is added downstream.
- Do I need a water softener on Shorelands System water?
- At 4.3 gpg, softening is optional — a maintenance and comfort decision rather than a necessary one.
Get your own tap tested
System-wide figures describe finished water leaving the plant. A test at your own tap is what tells you the hardness, iron and pH your plumbing actually sees.
Hardness is a nuisance parameter, not a regulated health contaminant. See the Learn hub for treatment comparisons, or how these figures are sourced.
