Kenner city core water, explained

Kenner, Jefferson Parish · PWS ID LA1051001

The short answer

Kenner city core water is hard, about 4.6 grains per gallon, chloramine-disinfected Mississippi River water. The recommendation for this water: a dedicated water softener and a separate whole-home catalytic carbon filter plus optional reverse osmosis at the kitchen sink.

The scale on faucets, shower glass, and inside water heaters starts with the hardness in this water. Kenner city core water is treated Mississippi River water. It tests hard at 78 milligrams per liter, about 4.6 grains per gallon, and carries chloramine at 1.9 parts per million. At typical household use, that moves roughly 71 pounds of hardness minerals through the house each year. Those minerals react with soap and collect as scale anywhere water is heated or allowed to dry. For perspective, chloramine in drinking water typically runs from 0.5 to 2 parts per million. At 1.9 parts per million, this system is near the high end of that range. Unless a pitcher or refrigerator filter specifically lists chloramine reduction, do not assume it removes it. A softener handles the hardness. It does not remove chloramine. That requires a separate catalytic-carbon tank.

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.

hardness at 4.6 grains per gallon · Scale inside water heaters and appliances, spots on fixtures, and soap residue on skin and hairA dedicated water softener handles it

Chloramine is made by combining chlorine with ammonia. It lasts longer than chlorine and can be much less obvious at the tap. These numbers come straight from your water utility's published report.

What we'd install

Based on the report, a dedicated water softener for the hardness and a separate whole-home catalytic-carbon tank for the disinfectant. Add reverse osmosis at the kitchen sink if better drinking water is part of why you're calling. If it isn't, the softener and catalytic-carbon system remains the whole-house recommendation, and RO stays off the quote.

**Dual-tank softener + catalytic carbon**One coordinated whole-house system for hardness and the disinfectant

**Reverse osmosis**Drinking water at the kitchen sink

What this does for your home

Stops hardness scale from continuing to collect inside water heaters and appliances
Soap lathers more easily without forming hardness residue on skin, hair, and shower surfaces
Fewer mineral deposits on faucets, fixtures, dishes, and glass
Reduces chloramine throughout the house, including showers and the water used for coffee, tea, and cooking
Filtered drinking water from its own kitchen faucet

Hard water leaves its record inside the equipment you depend on.

At 4.6 grains per gallon, hardness minerals can collect as scale on heating surfaces, inside fixtures, and throughout water-using appliances. That buildup makes water heaters work harder and can shorten equipment life.

A dedicated softener removes the hardness minerals before they can keep accumulating inside the house. Catalytic carbon handles the chloramine separately.

The public recordNo violations on record

The East Jefferson Waterworks system, which serves Metairie and Kenner, has a clean violation record. EPA shows no drinking-water violations as of August 2026. State surveys have repeatedly flagged finished-water-storage deficiencies, which are findings, not violations.

What this means at your house

Your water arrives with chloramine in it, at 1.9 parts per million. Utilities make chloramine by combining chlorine with ammonia so it remains effective farther through the distribution system. It can be less obvious than chlorine: some people notice a faint chemical taste or odor, while others notice nothing at all. Ordinary pitcher and refrigerator filters should not be assumed to reduce it unless chloramine is specifically listed. Catalytic carbon reduces it before the water reaches the house.

This is hard water. Hardness tests at 78 milligrams per liter, about 4.6 grains, and for a family using around 300 gallons a day that puts roughly 71 pounds of dissolved rock through the house in a year. That is why a softener goes in the package for this neighborhood.

The water here starts in the Mississippi River and is treated at the East Bank plant complex on Jefferson Highway before the trip across town to your tap. Chlorine also leaves traces behind as it works, called disinfection byproducts. This system's published reading is 125 parts per billion, and the carbon filter reduces those too.

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
Chloramine at 1.9 ppm	The taste and smell in coffee, tea, and the first glass of the day	Whole-home catalytic carbon	Chloramine holds together inside plain carbon. Catalytic carbon is processed to break it apart.
Hardness at 4.6 grains per gallon, hard enough to form scale	Scale inside water heaters, dishwashers, fixtures, and small appliance parts	Water softener	A softener stops hardness minerals from building up on heating surfaces and inside equipment.

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.
