Mandeville water quality

Northshore · Mandeville Water Supply · PWS ID LA1103023 · Southern Hills aquifer (groundwater)

The short answer

Mandeville water is soft, chloramine-disinfected aquifer groundwater. The fix: a whole-home catalytic carbon filter plus reverse osmosis for drinking water.

Mandeville water comes from the Southern Hills aquifer and arrives soft, with chloramine as the disinfectant. Here is what that means at your tap, and exactly what whole-home filtration does about it.

What we'd install

Here is your system: whole-home catalytic carbon for the chloramine at every tap, plus reverse osmosis at the kitchen sink for the water you drink and cook with. It is the setup we put in most Mandeville homes, and it earns its keep every single day.

Easier on the parts that wear out

Sediment settles in your water heater and lowers its efficiency, and chlorine and chloramine embrittle the rubber seals, gaskets, and hoses inside your appliances over time. Filtering the whole house is gentler on all of it.
