Based on the report, whole-home carbon for the chlorine at every tap. Add reverse osmosis at the kitchen sink if better drinking water is part of why you're calling. If it isn't, the carbon system stands on its own, and the quote prices the two on separate lines.
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.
U.S. Dept. of Energy Energy Saver; ASTM D6284.The Town of Madisonville system has a clean record. EPA shows no drinking-water violations as of August 2026.
Your water arrives with chlorine in it, at 0.8 parts per million. That is the disinfectant the Town of Madisonville uses, and it is the taste people notice in coffee, in ice, and in the first glass of the day. Carbon takes it out at every tap in the house.
This is soft water. Hardness tests at 9.1 milligrams per liter, about 0.5 grains, and for a family using around 300 gallons a day that puts roughly 8 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 Wells 1 and 2 in the Southern Hills aquifer.
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 0.8 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. |
| Hardness at 0.5 grains, soft | No scale problem to fix | No softener | The resin would have nothing to grab, so it stays out of the quote. |
