Penn Mill Place water, explained

Covington, St. Tammany Parish · PWS ID LA1103200

The short answer

Penn Mill Place water is soft, about 1.5 grains per gallon, chlorine-disinfected groundwater. The recommendation for this water: a whole-home catalytic carbon filter, a pH neutralizer, iron filtration, plus optional reverse osmosis at the kitchen sink.

If the tap water tastes like it came from the pool, this page is why. Penn Mill Place water carries chlorine at 2.3 parts per million, and it tests soft at 24.8 milligrams per liter, about 1.5 grains per gallon. For perspective, some people can taste or smell chlorine at levels as low as 0.3 parts per million. The published report also shows iron above the aesthetic limit, plus a pH of 5.72, on the acidic side.

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

Why this is the recommendation

What you may notice in your waterBeneath the surfaceWhat gets your attention?

What you notice

The smell and the way showers feel

Pool-like smell when the shower gets hot
Skin that feels tight or dry afterward
Hair that feels dry or harder to manage
Water, coffee, or tea that tastes off

What leaves a mark

The staining has a measured source

Iron and manganese can leave orange or dark marks in tubs, sinks, fixtures, and laundry. Treatment built for those metals goes ahead of the rest of the system.

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. The staining in tubs and laundry comes from the iron in the report, and filtration built for it takes it out.

What we'd install

Based on the report, whole-home catalytic carbon for the chlorine at every tap. A pH neutralizer goes in ahead of it to bring the water back to balance. Iron filtration handles the staining before it reaches your fixtures. Add reverse osmosis at the kitchen sink if better drinking water is part of why you're calling. If it isn't, the catalytic-carbon system remains the whole-house recommendation, and RO stays off the quote.

What this does for your home

Reduces the chlorine taste and smell in showers, coffee, tea, and cooking water
Built to remove the iron and manganese behind the tub and laundry staining
A neutralizer raises the low pH before the water reaches your copper plumbing
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.

The water keeps interacting with plumbing after the meter.

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 2.3 parts per million. That is the disinfectant the Penn Mill Place 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 24.8 milligrams per liter, about 1.5 grains, and for a family using around 300 gallons a day that puts roughly 23 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 Penn Mill Place Well. The report also shows iron above the aesthetic limit. That is what causes the staining that shows up in tubs, sinks, and laundry over time, and iron filtration is built for exactly that. The pH here runs acidic, at 5.72. Acidic water works on copper plumbing, which is where blue-green stains around drains come from. A neutralizer brings the pH back to balance ahead of everything else.

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 2.3 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 1.5 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.
pH of 5.72, acidic	Blue-green stains around copper drains	pH neutralizer	Bringing the pH back to neutral stops the water from working on your copper.
Iron above the aesthetic limit	Orange or dark staining in tubs, sinks, and laundry	Iron filtration	It is built for exactly this kind of staining.

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.
