Metairie water quality

Citywide service overview · East Jefferson Waterworks District 1 · PWS ID LA1051001 · Mississippi River (surface water)

The short answer

Metairie water is hard, 78 mg/l (about 4.6 grains), chloramine-disinfected Mississippi River water. The fix: a water softener, a whole-home filter, and reverse osmosis for drinking water.

Metairie water is treated Mississippi River water from East Jefferson Waterworks, the same system that serves Kenner. It is hard at 78 milligrams per liter, about 4.6 grains per gallon, and disinfected with chloramine. Its published report also shows individual disinfection-byproduct samples above the federal limits, while the running annual averages used for compliance stayed below them.

Scale is hard on your water heater

Hard water leaves scale that lowers water heater efficiency and shortens its life. In lab testing, tankless heaters run on hard water failed from scale in under two years, while the same units on softened water kept running.
