Monterey water, explained

Slidell, St. Tammany Parish · PWS ID LA1103148

See my full recommendation
The short answer

Monterey water is chlorine-disinfected groundwater. The recommendation for this water: a whole-home catalytic carbon filter plus reverse osmosis at the kitchen sink.

If the tap water tastes like it came from the pool, this page is why. Monterey water carries chlorine at 1.5 parts per million. For perspective, some people can taste or smell chlorine at levels as low as 0.3 parts per million. The white film left where tap water dries here is dissolved mineral, and a softener is not what removes it. Film on dishwasher-washed glasses is its own story, mostly the dishwasher's.

If the tap water tastes like it came from the pool, this page is why. 5 parts per million.

What Monterey reports

More than one number matters

  • chlorine, 1.5 ppm, about 5 times the level some people can detect
  • dissolved solids the water carries

What this report does not rule out

PFAS cannot be seen, smelled, or tastedPFAS are a large family of long-lasting manufactured chemicals. They are often called “forever chemicals” because they break down very slowly.

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.

The film on your glasses and fixtures is the part people ask about first. These numbers come straight from your water utility's published report.

Water systems in this area interlock and no public map draws the line, so we confirm which one serves your address before we quote anything.

What we'd install

Based on the report, whole-home catalytic carbon for the chlorine at every tap. Reverse osmosis at the kitchen sink is in this package for the film: it is the piece that clears the glasses you rinse at that tap, and drinking water and coffee come with it.

What this does for your home
  • Reduces the chlorine taste and smell in showers, coffee, tea, and cooking water
  • Spot-free glasses from the kitchen tap
  • 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.

What this means at your house

Your water arrives with chlorine in it, at 1.5 parts per million. That is the disinfectant the Monterey Subdivision 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.

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 68 milligrams per liter. Reverse osmosis at the kitchen sink takes the dissolved solids out of your drinking water, and glasses rinsed at that tap dry without the film.

The water here is groundwater, pumped from Monterey Well.

How the report becomes the recommendation

Each finding decides a piece of the package, including the pieces we leave out.

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 publishes no hardness figure, so any softener conversation starts with a test at your tap, never with this page.

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.
