Greater Hammond water, explained

Hammond, Tangipahoa Parish · PWS ID LA1105008

The short answer

Greater Hammond water is soft, about 0.3 grains, chloramine-disinfected groundwater. The fix for this system: a whole-home catalytic carbon filter plus reverse osmosis at the kitchen sink.

Greater Hammond water carries chloramine, and it tests soft at 5.8 milligrams per liter, about 0.3 grains. The white film on glasses and fixtures here is dissolved mineral left behind as water dries, and a softener is not what removes it.

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

Water system boundaries interlock around here, so we confirm yours by address before we quote anything.

What we'd install

Based on the report, whole-home catalytic carbon for the chloramine 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

Easier on the rubber seals, gaskets, and hoses inside your appliances
No chloramine taste or smell in your coffee, tea, and ice
Spot-free glasses from the kitchen tap
Bottled-quality drinking water on tap for pennies a gallon

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 public recordInventory-deadline paperwork only

EPA shows a Lead and Copper Rule item for the Tangipahoa Parish Water District dated October 2024. This was the federal service-line inventory reporting deadline that thousands of systems nationwide missed. It is a reporting deadline, not lead found in the water, and it was resolved. State surveys have flagged finished-water-storage deficiencies, which are findings, not violations.

What this means at your house

Your water arrives with chloramine in it. That is the disinfectant Tangipahoa Parish Water District uses, and it is what people taste in coffee, in ice, and in the first glass of the day. Chloramine does not gas off in a pitcher the way chlorine does, so catalytic carbon is the piece that 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 62.2 milligrams per liter. Reverse osmosis at the kitchen sink gives you clean drinking water and spot-free glasses at that tap.

This is soft water. Hardness tests at 5.8 milligrams per liter, about 0.3 grains, and for a family using around 300 gallons a day that puts roughly 5 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 the aquifer under your feet.

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	The taste and smell in coffee, ice, 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.
Dissolved solids, sodium at 62.2 milligrams per liter	White film on glasses and fixtures	Reverse osmosis at the kitchen sink	The membrane takes dissolved solids out, and the kitchen tap is where you taste them.
Hardness at 0.3 grains, soft	No scale problem to fix	No softener	The resin would have nothing to grab, so it stays out of the quote.
