Alderstone Water Company is a locally owned Louisville water treatment company. A Better Standard of Water. Better Water Starts Here.
Short answer: yes — Louisville-area city water is commonly disinfected with chloramine (often labeled total chlorine on utility language). That is related to pool chlorine, at a much lower dose, and it is more stable in the distribution lines. Hot showers release the odor into the air. Coffee and tea pick up the taste. None of that means city water is unsafe. It means the disinfectant is doing its job — and some homes want that taste and smell gone.

Does Louisville water have chloramine?
Louisville Water treats Ohio River water for metro customers and keeps disinfectant in the system so lines stay protected end to end. Homeowners usually say “chlorine.” On this utility’s city supply, what you are often smelling and tasting is chloramine — ammonia combined with chlorine — also discussed as total chlorine.
We are not rewriting a utility lab report on this page. We are naming what Louisville-area city homes actually notice at the faucet:
- Pool or “medicinal” smell in a hot shower
- Flat or chemical taste in coffee, tea, or ice
- The same note at more than one cold tap after the line has run
City water is treated and regulated. This is not a scare page and not a contaminant scorecard. If the glass of water smells fine and only the drain smells, start with the drain — same practical check described on chlorine smell in water.
Chloramine vs free chlorine (why the pitcher trick fails)
Free chlorine (the classic pool chemical) can air out of a glass more readily. Chloramine is more stable. Leaving a pitcher on the counter, boiling a pot, or running the tap longer usually does little for shower smell. A fridge pitcher may take the edge off one glass. It does nothing for the upstairs bath, the laundry, or every other fixture.
That stability is why “we already have a softener” and “we already boil water” still leave the bathroom smelling like the plant. Softening and boiling are different jobs from disinfectant reduction at the point of entry.
What chloramine is (and is not) for Louisville homeowners
Chloramine / total chlorine in city lines is a taste and odor conversation at the house — especially the shower and the drinking glass.
It is not:
- Hardness (spots, film, lazy soap) — that is a water softener / Do I Need a Water Softener in Louisville? conversation
- Well sulfur (“rotten egg”), iron stain, or cloudy grit — that is a city or well fork first
- A claim that Louisville tap water is unsafe to drink
- Something a softener “also handles” as a bonus
If spots and shower smell both bother you, you usually have two jobs. Spots = hardness. Pool smell / chloramine taste = filtration. Mixing those into one vague “water system” pitch is how people buy the wrong tank. Meta and phone intake use the same split: spots/soap/scale · chlorine smell/taste · drinking water · city or well — so say it that plainly on the call.
Softener ≠ chloramine fix
A conventional salt softener exchanges hardness minerals on resin. It does not adsorb chloramine the way carbon media is used for taste and odor. Softened water can still smell like the plant in a closed bathroom.
Full answer: Does a Water Softener Remove Chlorine?. Softener local page: water softener installation in Louisville. Hard-water symptoms: Hard Water Louisville.
Keep the softener if spots and scale are real. Add a filtration conversation for chloramine smell — do not expect the softener alone to clear it.
What helps chloramine taste and smell (high level)
Match the fix to where it bothers you. We stay high-level here — no media brand names, no certification stacks, no “removes everything” language.
Every tap, including the shower
A whole-home filter (point-of-entry) is the usual city-home path when the pool smell hits you in the bathroom. Showers, laundry, and every faucet see the same treated water. Louisville whole-home filter page: whole-home filter in Louisville. How that class of equipment is framed: whole-house water filter Louisville.
Catalytic / carbon-style whole-home paths are the common industry approach for chloramine taste and odor at every tap. Exact media and layout belong on the quote call — not in a blog claim table.
Just the drinking and cooking glass
Reverse osmosis is kitchen equipment with its own faucet. It will not change the shower. People pick it for coffee, cooking, and fewer cases of bottled water. RO is the glass — not the softener, not the whole-house smell fix.
Both shower smell and the glass
That is often whole-home filtration plus kitchen RO — two jobs, clearly named. Pairing page: /whole-home-systems/.
Spots on glasses at the same time

City vs well — say it first
Chloramine talk is a city-line story. Wells are a different service type.
- City (Louisville Water and similar metro city service): disinfectant taste/odor + hardness are the usual pair.
- Well: iron, sulfur, sediment, and hardness often matter before anyone talks city carbon. Do not quote a city chloramine filter for a sulfur well.
Start-here fork: City or Well Water in the Louisville Area — Start Here. Town hubs for local context: Louisville, Middletown, Jeffersontown, Prospect, Crestwood, La Grange, Shelbyville, and the other GBP towns on the site. North Shelby / Shelbyville / La Grange / Middletown homeowners on city lines still use the same city-vs-well question — we do not invent a separate utility claim for each town on this page.
Local intent: where Louisville-area homeowners notice it
Calls sound the same from Highlands and Crescent Hill to Middletown, Jeffersontown, Prospect, Crestwood, Lyndon, St. Matthews, Hurstbourne, Anchorage, and out toward La Grange and Shelbyville:
- “The shower smells like a pool.”
- “Coffee tastes off.”
- “We put a softener in and the smell is still there.”
- “Is it chlorine or chloramine?”
Those are chloramine / disinfectant questions on city water — not a reason to invent hardness numbers or toxin lists. If you only care about spots and soap, start with hard water Louisville instead.

How to decide in one phone call
You do not need a house visit to start.
- City or well?
- What bothers you most? Chlorine/chloramine smell or taste · spots/soap/scale · drinking glass · well iron/sulfur/cloudy · or more than one.
- Town or ZIP (Louisville Metro and surrounding GBP towns).

FAQ
Does Louisville water have chloramine?
Louisville-area city supply is commonly disinfected with chloramine (total chlorine). Homeowners often call it chlorine. For smell/taste context: chlorine smell in water.
Is chloramine the same as pool chlorine?
Related chemistry, different use. Utility chloramine is a low-dose, stable disinfectant in the lines — not a pool. Hot showers make the odor more noticeable.
Will a water softener remove chloramine?
No. Softener = hardness. Filtration = chloramine taste/odor. Does a Water Softener Remove Chlorine?
What system helps chloramine smell in the shower?
A whole-home (point-of-entry) filter path — see whole-home water filter and /whole-home-systems/. Kitchen RO alone will not fix the shower.
Does reverse osmosis fix chloramine in the whole house?
No. RO is the kitchen drinking/cooking faucet. /reverse-osmosis/louisville-ky/
I’m in Middletown, Shelbyville, or La Grange — does this still apply?
If you are on city water, the chloramine / disinfectant conversation is the same class of issue. If you are on a well, start with city or well. We do not invent town-by-town utility chemistry on this page.
Will you come to the house to decide?
No. We quote by phone or text. Call or text 502-865-9330 or use get a chloramine filtration quote.
