What's in Madisonville Woods water

Madisonville, St. Tammany Parish · PWS ID LA1103147

The short answer

Madisonville Woods water is soft, about 0.4 grains per gallon, chlorine-disinfected groundwater. The recommendation for this water: a sediment prefilter when suspended material is confirmed at the house, a whole-home catalytic carbon filter, plus optional reverse osmosis at the kitchen sink.

If the tap water tastes like it came from the pool, this page is why. Madisonville Woods water carries chlorine at 1.4 parts per million, and it tests soft at 6.6 milligrams per liter, about 0.4 grains per gallon. For perspective, some people can taste or smell chlorine at levels as low as 0.3 parts per million.

If the tap water tastes like it came from the pool, this page is why. 4 grains per gallon.

What this report does not rule out

PFAS cannot be seen, smelled, or tasted

This report does not include a usable PFAS result. No result is not the same as no PFAS. Certified kitchen reverse osmosis reduces PFOA and PFOS in the water used for drinking and cooking.

That pool taste in your coffee and morning glass is chlorine, the disinfectant this system uses. Everything here is published data for this water. The recommendation follows from it.

What we'd install

Based on the report, whole-home catalytic carbon for the chlorine at every tap. Sediment can vary house to house in the Madisonville area. If we find grit or suspended material at your tap, a whole-home sediment prefilter goes first in the treatment line. Reverse osmosis at the kitchen sink is optional, for drinking water and coffee. The whole-house recommendation remains the catalytic-carbon system either way.

What this does for your home

Reduces the chlorine taste and smell in showers, coffee, tea, and cooking water
No unnecessary softener for water that already tests soft
Filtered drinking water from its own kitchen faucet

Cutaway of a water heater with sediment settled at the bottom

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.

Clear at the faucet does not show you the trip it took.

Before water reaches your glass, it travels through the public distribution system, your service line, and the plumbing inside your house. These are the surfaces people never see.

What this means at your house

Your water arrives with chlorine in it, at 1.4 parts per million. That is the disinfectant the Madisonville Woods system uses, and it is the taste people notice in coffee, in tea, and in the first glass of the day. For perspective, some people can taste or smell chlorine at levels as low as 0.3 parts per million. Catalytic carbon takes it out at every tap in the house.

This is soft water. Hardness tests at 6.6 milligrams per liter, about 0.4 grains, and for a family using around 300 gallons a day that puts roughly 6 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 Madisonville Wells 1 and 2.

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
Possible sediment after utility treatment	Grit in aerators, toilet tanks, and small valves	Sediment prefilter when confirmed at the house	Sediment can enter from mains, service lines, or home plumbing, so the annual report cannot tell us whether your house needs this stage.
Chlorine at 1.4 ppm	The taste and smell in coffee, tea, and the first glass of the day	Whole-home catalytic carbon	Chlorine sticks to carbon on contact, and a full-size tank gives the water that contact time.
Hardness at 0.4 grains per gallon, soft	No scale problem to fix	No softener	The resin would have nothing to grab, so it stays out of the quote.

It cannot say what is causing dry skin at your house. Hot water, soap, weather, and the disinfectant can all contribute, and the report only establishes that the disinfectant is present.

It cannot speak for the pipes inside your own walls. Lead sampling covers a handful of homes across the whole system, and your service line, solder, and fixtures are yours alone.

It says nothing about sediment at your particular faucet; annual reports do not measure what collects in one house.

Before anything goes on a quote, we ask what you are actually noticing and test whatever the published data cannot answer.
