Delaware/Western System water quality
Hard25 municipalities · Burlington, Camden
Delaware/Western System reports water hardness of 7.5 grains per gallon — 128 mg/L as calcium carbonate, hard on the USGS scale. Because the reading is taken on finished water leaving treatment, it is the figure for all 25 towns on this system rather than for any one of them.

- How hard is Delaware/Western System water?
- Delaware/Western System reports hardness of 7.5 grains per gallon (128 mg/L as calcium carbonate), which the USGS scale classifies as hard. The figure is a system-wide reading and applies to every municipality on the system.
- Which towns are served by Delaware/Western System?

- Why do towns on Delaware/Western 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 Delaware/Western System therefore reports the same value.
- How much sodium is in Delaware/Western System water?
- Delaware/Western System reports sodium at Not listed as detected in this CCR. 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 Delaware/Western System water?
- At 7.5 gpg, ion-exchange softening is generally worth considering.
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.
