Let's be real—nobody likes opening a utility bill. But for Garden City residents, the latest water bill wasn't just an annoyance; it was a shock.
If you live near Stewart Avenue, the Estates Section, or heavily residential blocks like Eleventh Street, you've likely noticed your water costs climbing significantly. You aren't imagining it. Rates have jumped nearly 20% this year.
For years, Garden City residents enjoyed relatively low water rates compared to other Long Island towns. But that era is over.
Why? It's not just inflation. It's not just "administrative costs." You are paying for a massive, necessary, and expensive infrastructure project designed to fight a chemical you can't taste, smell, or see: 1,4-Dioxane.
I've been testing water on Long Island for over 15 years, and I tell my customers the same thing: The Village is doing its job to meet the legal standards. They are spending millions to upgrade the treatment plants. But meeting a "legal standard" at the source and delivering pristine water to your tap are two very different things.
This guide will explain exactly what you are paying for, what 1,4-Dioxane actually is, and why your expensive municipal water might still taste like a swimming pool by the time it reaches your shower.
To understand your bill, you have to understand the construction you've seen at the Eleventh Street water plant and well sites (specifically Well Nos. 7, 8, 9, 10, 11, 13, and 14).
The Village has been forced to install Advanced Oxidation Process (AOP) systems. This isn't just a standard filter; it's a chemical reactor.
"All the wells owned and operated by the Village of Garden City have the AOP treatment systems, and we are now in full compliance with New York State's mandate."
1,4-Dioxane is a synthetic chemical used in industrial solvents, degreasers, and even some cosmetics. According to Garden City Park Water District, it's used in "everyday household products such as cosmetics, detergents, shampoos, deodorants, sunscreens and more."[2]
For decades, it was used in manufacturing across Long Island, and because our sandy soil (the Magothy Aquifer) is so permeable, it seeped into the groundwater.
The EPA identifies it as a "likely human carcinogen." Unlike other contaminants, it doesn't break down easily in nature—hence the nickname "forever chemical."
For a long time, water districts didn't know how to handle it. Standard carbon filters—the kind used in simple pitchers or old-school systems—do not target 1,4-Dioxane effectively. It slips right through.
To fight it, Garden City had to build AOP reactors at all well sites. Here is how it works:
Industrial-strength hydrogen peroxide is injected into the water supply.
Water passes through a massive chamber filled with high-intensity Ultraviolet Light.
UV + Peroxide create "hydroxyl radicals" that tear 1,4-Dioxane molecules apart.
According to official documentation from Garden City Park Water District: "The primary treatment mechanism involves the reaction of UV light with a strong oxidizing agent like hydrogen peroxide or chlorine to generate highly reactive hydroxyl radicals."[2]
This technology is incredible. It works. But it is expensive. It requires massive amounts of electricity and constant chemical resupply. That is what your rate hike is paying for.
"We're proceeding with Advanced Oxidation Process (AOP) reactors in Wells 6 and 9. Preventive treatment puts us ahead of the curve. Things may look a bit messy during construction, yet this is our tax payer dollars at work."
You might remember receiving notices over the last two years about a "Deferral" from the New York State Department of Health. Many residents tossed these in the trash, but they were important.
A "Deferral" is essentially a hall pass.
When New York State set strict new limits for 1,4-Dioxane at 1 part per billion (ppb) effective August 26, 2020, Garden City's wells were testing above the limit.[3] Because they couldn't build the AOP plants overnight, the State granted them a deferral to continue serving non-compliant water while construction was underway.
According to the Village of Garden City's 2024 Water Supply Report: "The Deferral ended on May 25, 2023 and the Village is in full compliance."[3]
This history highlights a critical fact about Long Island water: The infrastructure is often reactive, not proactive. We often find out about contaminants only after we've been drinking them for years.
So, you are paying ~$8.87 per 1,000 gallons for this high-tech, AOP-treated water. It should taste like mountain spring water, right?
Wrong.
Residents in Garden City are still complaining about two major issues:
The AOP system does not target hardness. You are paying a premium for water that still ruins your appliances.
When residents see their water bill go up, the knee-jerk reaction is to stop drinking tap water and buy bottled water. I see pallets of Poland Spring and Fiji being delivered to driveways on Stewart Avenue every day.
This is a financial and environmental mistake.
The Cost Calculation
Let's do the math for a standard family of four in Garden City:
You are now paying a premium water bill to the Village AND an $1,800 "tax" to Nestlé or Coke for bottled water.
The Microplastic Problem
It's not just the money. A recent study by Columbia University (and others) found that bottled water can contain hundreds of thousands of nanoplastic particles per liter. You are paying to drink plastic.

You are already paying for the "Heavy Lifting" (AOP) at the street level. The Nell System is the "Final Polish" for your home.
Think of the municipal treatment as a "Shotgun" approach—it blasts the big threats. The Nell System is the "Sniper"—it targets the specific residual contaminants, tastes, and textures that ruin your daily experience.
Most "old school" softeners use massive bags of salt. They replace calcium with sodium.
Many people ask about Reverse Osmosis (RO) for the whole house. We generally advise against it for whole-home use because it strips everything out, leaving water acidic and "dead."
To fix that "Pool Smell," we use a specific catalytic carbon blend.
It's not just drinking water. You shower in it. Your pores open up in hot water, absorbing chlorine. You wash your clothes in it.

The Situation:
The Miller family lives in a beautiful historic home on Stewart Avenue in Garden City. In January 2026, right as the new AOP plant ramped up, they noticed a change.
The Fix:
We installed a pHountain Nell System on January 20, 2026. The installation took one day. Our in-house plumbers (we never subcontract) handled the connection cleanly in their finished basement.
"I was skeptical that a filter could fix the smell, but honestly, our tap water tastes like Fiji water now. The chlorine smell is gone instantly. My daughter's skin is calmer, and we canceled the water delivery service the next day." — Sarah M., Garden City
The ROI:
The Millers are saving $1,920/year by cutting bottled water. The system pays for itself in just over 2 years, while protecting their new $4,000 tankless water heater from scale.

How much does a whole house filter cost?
Every home is different (plumbing size, water usage), but generally, the system costs less than what a family spends on bottled water over 2-3 years. It pays for itself.
Does this target PFAS and 1,4-Dioxane?
Yes. While the Village AOP system does the heavy lifting, our systems are designed to target specific "forever chemicals" found in Long Island groundwater, acting as a final barrier to what the municipal plant might miss or what enters through the pipes.
Is Garden City water safe in 2026?
The Village meets EPA compliance standards. However, "compliance" allows for trace levels of contaminants. If you want zero worry, you need a final barrier.
What is the difference vs. a traditional softener?
Traditional softeners use salt bags and waste water. Our Nell system is salt-free, wastes no water, and requires zero weekly maintenance. It is the modern solution for Garden City homes.
Why is my water bill so high?
You are paying for the new AOP treatment plants. The best way to get value from that money is to ensure the water is actually perfect when you drink it.
Do you test for 1,4-Dioxane?
We offer comprehensive free water testing. While standard field tests check for hardness, chlorine, and iron, we can arrange for detailed lab analysis for specific contaminants if requested.
