Mandeville, St. Tammany Parish · PWS ID LA1103118
Greenleaves water carries chloramine at 1.8 parts per million, and it tests soft at 13.5 milligrams per liter, about 0.8 grains. The white film people here find on glasses and fixtures is the dissolved minerals the water carries, and a softener would never touch that.

Magnolia-Greenleaves (CSWR) · PWS ID LA1103118 · 2025 water quality report
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, cook with, and freeze. It is the setup we put in most homes on this water, and it earns its keep every single day.
Your water arrives with chloramine in it, at 1.8 parts per million. That is the disinfectant Magnolia-Greenleaves (CSWR) uses, and it is what people taste in coffee, in ice, and in the first glass of the day. Chloramine does not gas off in a pitcher the way chlorine does, so catalytic carbon is the piece that takes it out, at every tap in the house.
The white film on glasses and fixtures is the dissolved minerals the water carries, including sodium at 59 milligrams per liter, drying wherever the water evaporates. Reverse osmosis at the kitchen sink gives you clean drinking water, clear ice, and spot-free glasses at that tap.
The water here is groundwater, pumped from Greenleaves Well, Meadowbrook Well.
