Water Softener Installation in Longport, NJ

Longport is supplied by Longport Water Department, which draws ground water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.

Where the water comes fromGround water in Longport

Ground water has spent time in contact with rock, and that contact is what puts calcium and magnesium into it. How much depends on what the rock is made of — limestone country produces the hardest water in the country.

Longport Water Department serves 1,192 service connections. The system reports that figure to the EPA itself; this is the 2026 Q2 data.

What to do with thatGet your hardness figure

Ask Longport Water Department for its water quality report, or find it online — hardness is on it, and it is the number the rest of this turns on. That figure comes in milligrams per liter. Divide by about 17 to get the grains per gallon a softener is rated in.

Then run the arithmetic: it tells you the capacity you need rather than the capacity you are offered. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
