Source water

Atlanta drinks from a river.

The Chattahoochee starts in the North Georgia mountains, fills Lake Sidney Lanier, and runs southwest past the city's intakes.

0people on the City of Atlanta's water system1

One river. Three plants. 2,790 miles of pipe.

Hemphill, treating water since 1893, and the Chattahoochee plant make 75 percent of Atlanta's water. The Atlanta-Fulton County plant makes the rest. That's about 105 million gallons a day.23

Then comes the last mile.

Most testing happens at the plant and in the pipes up to the curb. From the curb to your tap is the last mile, and almost nobody measures it at scale. Atlanta's 2025 report found no lead service lines. Inside buildings, it's another story.2

0of Atlanta school buildings had high lead in at least one fountain or sink6

Then you fill your glass.

The city screens for more than 150 contaminants. Twelve show up in the public record. Here they are, one reading at a time.2

Legal isn't always clean.

Each reading is real, with its date. Hover over a particle with the test strip, or over a name here.

PFOA and PFOS weren't detected. Also tested and inside the limits: chlorine 1.13 ppm (limit 4), turbidity 0.09 NTU, total organic carbon 1.4 ppm, total coliform 2.0% of samples in the highest month (limit 5%).

62ELEVATED

Finding: lead at home taps (90th percentile, 2024) is 7 times California's public health goal. Everything else measured in 2024–25 is under its health limit in our method.

Basis: measured, from the City of Atlanta 2025 Water Quality Report and EPA testing. Method v2.0.0, October 15, 2026. An independent science panel is forming to review the method.

AquaScore describes what was measured or modeled against health benchmarks. It is not a determination that water is safe or unsafe to drink.

Aquagenuity®

The credit score for water quality.

Aquagenuity® is a water intelligence company. We turn public water data into a score anyone can read, for every home, school and city.

We use the most advanced data science and proprietary AI foundation models to score the water at locations across the country — then put that data in the hands of the people who drink it.

We don't sell water. We grade it.

  • Credit scoreOne number anyone can read, built from records most people never see.
  • Weather serviceWe alert. Officials declare.
  • Lab reportWe say what was measured. We never call water safe or unsafe.

How it works

Two numbers. One gap.

Every contaminant has a legal limit. Science often sets a far lower health limit. The distance between them is the AquaGap™, and it's where most of the story lives.

  1. Gather

    We start with the public record.

    Federal and state drinking-water data, utility reports and permits. Then Guardians test the last mile, from the curb to the tap, where the public record stops.

  2. Score

    We hold it to both numbers.

    Every address gets an AquaScore™ from 0 to 100 and one plain word for what was found, from TRACE (barely there) to SEVERE (over the legal limit). Every score also tells you if it was measured or estimated, and when.

  3. Alert

    We tell you when it changes.

    A spill upstream, a new reading, a new rule. AquaAlert™ is being built to send alerts to people when it matters most.

What you can do

We are W.A.T.E.R.

We Are the Earth's Restorers. Five things anyone can do, and why each one matters.

  1. Watch

    Know your AquaScore™ and get notified when something changes near you.

    Water changes with the weather, with new construction, with farms and factories upstream. Last year's report can't tell you about last week.

  2. Ask

    Ask for the record. Every utility publishes a water quality report once a year. Read it, and ask what isn't in it.

    The report covers the plant and the pipes to the curb. It doesn't cover the last mile to your tap.

  3. Test

    Test the water where you actually drink it: your tap.

    Federal lead rules ask a city Atlanta's size to sample about 100 homes, for more than a million people. Home tests fill that gap and teach our models to predict what nobody's measured.

  4. Equip

    If you filter, match the filter to what's in your water.

    Filters don't all remove the same things. Look for independent certification that names the contaminant. Buy the claim, not the box.

  5. Report

    Report a water problem the moment you see it.

    When Atlanta's water mains broke in 2024, residents criticized the city for poor communication. One report, in one place, reaches the people who can act.

From the news

There's a lot of us and we're sick. We don't know what's next.

Stormy Bost, Calhoun, Georgia, speaking to the Associated Press, May 2026

Stormy Bost grew up in Calhoun, a carpet-mill town in northwest Georgia, and is raising two daughters there. Her family drank from the faucet. Then she learned the tap water carried PFAS, the "forever chemicals." An AP investigation found that Georgia officials had known about the pollution for years.

Nobody told her. Telling people is the whole job.

Why it matters

A lot of America's water has never been tested at the tap.

The Flint River, Georgia 20,000 gal.

Jet fuel leaked from the world's busiest airport into a drinking-water river, and nobody caught it for eight days.

The Flint River starts beneath Hartsfield-Jackson and supplies drinking water to more than 400,000 people in five counties. Downstream in Griffin, residents were told not to drink the water. In July 2026, the Flint Riverkeeper and the Southern Environmental Law Center gave notice they'd sue, saying the airport has "repeatedly spilled jet fuel, sewage, deicing fluid, and other pollutants."

Georgia schools 96

Georgia offered schools money to test for lead. 96 signed up.

More than 2,300 schools and 3,100 day cares were eligible. Of the facilities that tested, 37 percent had at least one tap above the federal action level.

Honest answers

What people ask first.

Is my water safe?

We don't call water safe or unsafe. Your score tells you what was measured or modeled against health benchmarks, how sure we are, and what to do next: watch, ask, test, equip or report.

Where does the data come from?

Public records first: federal and state drinking-water data, utility reports and permits. Then citizen-science tests from Guardians, and lab results where we have them. Every source is listed.

Does anyone pay to change a score?

No. We don't sell water, and nothing we rate is something we sell. Certification is separate and runs behind a firewall.

What if there's no score for my address yet?

You'll see the federal limits that apply everywhere, the public record upstream of you, and how to get your water tested. Guardians help us fill the map.

What don't you know yet?

A lot of America's water has never been tested at the tap. Where we model instead of measure, we say so, and we show our confidence.

Guardians of H2O™

Someone was always watching. Never every tap. Now fewer are watching.

Utilities and regulators watch the plants and the pipes. Nobody has ever watched every tap. And in 2025, EPA eliminated its research and development office. Guardians watch the last mile.

Guardians of H2O™

Guardian Season 2027

March 15 to June 5. 82 days, about one school semester. It opens on World Consumer Rights Day and closes on World Environment Day.

What happens

Guardians in every community gather a baseline for the water where they live, at the same time and the same way:

  • testing at home and at school, where kits are available
  • reading the local water record, from the utility's report to permits upstream
  • bringing what they find to a community conversation about their local water

Why a season

The public record stops at the curb. One coordinated season of Guardians testing the last mile gives every community a baseline it never had, makes results comparable from town to town, and gives our models the ground truth they need to predict what nobody has measured.

Why spring

Spring brings heavy rain and runoff from roads, farms and construction. It's when a baseline matters most, and it fits inside the school year.
