The public recordResolved byproduct violation on record
EPA lists a Stage 2 disinfection-byproduct violation for this Magnolia Water system in 2022, when total trihalomethanes measured 0.086 mg/L against the federal limit of 0.080. It was resolved that year. Disinfection byproducts form when chlorine reacts with organic material in the water. Its operator, Magnolia Water, is under a Louisiana Public Service Commission investigative audit of its billing and service practices, due February 2027.

What this means at your house
Your water arrives with chlorine in it, at 1.4 parts per million. That is the disinfectant the Cherrywood system uses, and it is the taste people notice in coffee, in ice, and in the first glass of the day. For context, swimming pools are kept between 1 and 3 parts per million of chlorine. This water arrives in that same range. Carbon takes it out at every tap in the house.
The white film on glasses and fixtures is dissolved mineral left behind as water dries. In this system's published report that shows up as sodium at 193 milligrams per liter and a pH of 8.82. On the pH scale, where 7 is neutral, 8.82 leans toward the baking-soda end, and alkaline water leaves its minerals behind as it dries. Reverse osmosis at the kitchen sink gives you clean drinking water and spot-free glasses at that tap.
This is soft water. Hardness tests at 1.6 milligrams per liter, about 0.1 grains, and for a family using around 300 gallons a day that puts a couple of pounds of dissolved rock through the house in a year. Genuinely hard water runs well past a hundred pounds a year, and that difference is why a softener is not in the package for this neighborhood.
The water here is groundwater, pumped from Cherrywood Well. One chlorine byproduct sample came in at 87.6 parts per billion, above the federal limit of 80, while the annual average that decides compliance stayed under it. Whole-home carbon reduces byproducts, which is one more reason the carbon filter earns its place here.
How the report becomes the recommendation
Each finding decides a piece of the package, including the pieces we leave out.
| The report shows | At your house | The answer | Why that one |
|---|
| Chlorine at 1.4 ppm | The taste and smell in coffee, ice, and the first glass of the day | Whole-home carbon | Chlorine sticks to carbon on contact, and a full-size tank gives the water that contact time. |
| Dissolved solids, sodium at 193 milligrams per liter | White film on glasses and fixtures | Reverse osmosis at the kitchen sink | The membrane takes dissolved solids out, and the kitchen tap is where you taste them. |
| Hardness at 0.1 grains, soft | No scale problem to fix | No softener | The resin would have nothing to grab, so it stays out of the quote. |
| One byproduct sample above the federal limit | What the disinfectant leaves behind in the water | Whole-home carbon | Carbon reduces byproducts along with the chlorine itself. |
