Greater Hammond water, explained

Hammond, Tangipahoa Parish · PWS ID LA1105008

See my full recommendation
The short answer

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

Chloramine is easier to miss than chlorine because its smell is less obvious. Greater Hammond water carries chloramine at 1.9 parts per million, and it tests soft at 5.8 milligrams per liter, about 0.3 grains per gallon. 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. 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.

Chloramine is easier to miss than chlorine because its smell is less obvious. 3 grains per gallon.

What you may notice in your waterBeneath the surfaceWhat gets your attention?
Why it is easy to miss

Chloramine can be present without a strong smell

The report confirms chloramine in this water even if you do not notice the obvious pool smell associated with chlorine. Ordinary pitcher and refrigerator filters should not be assumed to reduce it unless chloramine is specifically listed.

  • A faint chemical taste or odor, or no obvious warning at all
  • Skin that feels tight or dry afterward
  • Hair that feels dry or harder to manage
  • Water, coffee, or tea that tastes off
What Greater Hammond reports

More than one number matters

  • chloramine at 1.9 ppm, near the high end of the typical 0.5 to 2 ppm range
  • hardness at 0.3 grains per gallon
  • 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.

chloramine at 1.9 ppm, near the high end of the typical 0.5 to 2 ppm range · Made to last longer and often less noticeable than chlorineCatalytic carbon removes it throughout the house
hardness at 0.3 grains per gallon · Already soft water, with no hardness problem to treatNo softener recommended
dissolved solids the water carries · White film where tap water dries on fixtures and glassReverse osmosis handles it at the kitchen tap
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 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
  • Reduces chloramine throughout the house, including showers and the water used for coffee, tea, and cooking
  • Spot-free glasses from the kitchen tap
  • 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 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, 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.

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 takes the dissolved solids out of your drinking water, and glasses rinsed at that tap dry without the film.

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.

Chloramine at 1.9 ppmThe taste and smell in coffee, tea, and the first glass of the dayWhole-home catalytic carbonChloramine holds together inside plain carbon. Catalytic carbon is processed to break it apart.

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.
