Hartenwell Field Report

At a Congressional Hearing, the Chairman of the EMP Commission Was Asked If 9 in 10 Americans Could Die Within a Year of Losing the Grid. His Answer: “In the Correct Range.” — And the Overlooked Reason Why

Updated October 2026

Map of the United States with thick red marker circles around cities that lost safe tap water, Wichita circled twice — FIG. 1 — US cities placed under boil-water orders after power or pressure failures, 2021–2026. Circled: Wichita, September 16, 2026.

It wasn't the blackout he was worried about. It was what stops when the power stops.

Your faucet is an electrical appliance. The plant that cleans your water, the motors that push it, the pressure that brings it up to your sink: every piece of it draws from the same grid as your lights.

Nobody says that in the alert. The alert says “boil your water.” It arrives on your phone, in the dark, next to a stove that doesn't work.

Here is what has actually happened in American cities in the last five years. And what the families who stopped waiting are doing about it.

The Dependency Nobody Puts in the Alert

When the Power Dies, the Water Follows — Sometimes Within the Hour

Ask around: almost everyone assumes the water will still run after the lights go out. It's underground, it's piped in, it feels permanent.

It isn't. Every drop that reaches your kitchen gets there because a motor somewhere is turning.

Wichita, Kansas, September 16, 2026. A thunderstorm cut power to the city's treatment plant for forty-five minutes. Forty-five. Pressure fell below the safety line, and roughly half a million people were told not to drink from their taps — for one to four days depending on the town. Three weeks ago.

Here is how it falls apart, in the order it has actually happened:

Hour 1 — The plant goes darkPumps, filters and treatment all run on power. In Cleveland in August 2003, all four pumping stations fell at the same time. The mayor's words: “This wasn't supposed to happen.” 1.5 million people without water.

Hours 2–6 — The pressure dropsNothing is pushing anymore, so whatever was left in the mains drains downhill. Faucets sputter, then go quiet. When pressure drops, whatever is in the ground around a cracked pipe gets pulled in. That is why the boil notice follows.

Hours 6–12 — The tower runs outA water tower is a reserve for a short outage: hours of pressure, not days. Houston, Thanksgiving weekend 2022: one power failure at one plant, and 2.2 million people were boiling water. Schools closed.

Week 1 and after — Nobody comes as fast as you thinkRichmond, Virginia, January 2025: a winter storm knocked out the plant, the backup batteries had never been maintained, and a state capital went six days without safe water. The state's own investigation called it “completely avoidable.” Asheville, North Carolina, after Helene: seven weeks under a boil notice.

None of those cities were attacked. Nobody dropped a bomb. A storm, a cold snap, a battery nobody checked.

And this summer it got stranger. In the last week of July 2026, the FBI said hackers had broken into municipal water systems in at least seven states, changed passwords, and locked operators out of their own controls. Some of the biggest intrusions “resulted in boil water notices.” Twenty months earlier, the EPA's own Inspector General had counted 97 drinking water systems serving 26.6 million Americans with critical or high-risk security flaws.

The water doesn't disappear. The electricity behind it does.

The Garage Math Nobody Finishes

Every Case of Bottles Has a Date on It

A garage wall stacked with cases of Dasani, Aquafina and Poland Spring bottled water — FIG. 3 — Fifteen cases. For a family of four at the federal minimum, that is about eleven days.

There are a few cases of water in the garage. It feels like enough. Finish the math, just once.

The federal guideline is one gallon per person per day — minimum, “for drinking and sanitation,” and it tells you to store it “for several days.” Not three. Several.

A case of 24 bottles is about 3 gallons. A family of four needs 4 gallons a day just to stay at the minimum — before the pasta water, the dog, the toothbrushes, the baby's bottles.

Six cases = Thursday.

Twelve cases = next Wednesday.

Now look at how long it actually lasts:

Texas, February 2021 — more than 14 million people under boil notices in the same week. Store shelves were empty by the second day.
Jackson, Mississippi, 2022 — about seven weeks under advisory, days with no pressure at all, the National Guard handing out bottles.
Asheville, 2024 — 52 days.
Paterson, New Jersey, August 2025 — a 140-year-old pipe cracked; 200,000 people, more than a week. A resident told the news: “Every day, it's two more days.”

A stack of bottles only gets shorter. And the day it reaches the floor, the notice is still on your phone and the store shelf is still empty.

A stack of bottles isn't a plan. It's a calendar.

The Families Who Stopped Counting Bottles

Don't Store Water. Make It.

A hand holding a glass jar of murky brown creek water in a suburban backyard — FIG. 4 — There is almost always water nearby. The question is what's living in it.

Here's the part the alert never mentions: you are almost never out of water. There is a creek behind the school, a pond at the end of the development, a rain barrel, a swimming pool, a bathtub you filled when the warning came.

The problem is what's living in it.

Bacteria. Salmonella, E. coli and the rest of that family multiply in still water and in anything a pipe break pulls in from the ground. One mouthful and you're losing fluids faster than you can replace them. When there's nothing clean to drink to make up for it, dehydration is what puts people in the hospital.
Parasites. Giardia and cryptosporidium can't be seen, and no state is free of them. In 1993 cryptosporidium got through a treatment plant in Milwaukee: 403,000 people sick, 69 dead — from “treated” city water.
Runoff. Every rain washes animal waste and fertilizer off lawns and fields into whatever water is downhill. The retention pond at the end of your street is usually the dirtiest water for miles.
Algae and sludge. Stagnant water goes green and foul.
Sediment. Sand, silt, rust — and everything hiding in it.

Drink it untreated and you've swapped a water problem for a hospital problem.

So prepared families changed one question. Instead of “how many gallons can I fit in the garage?” (every answer to that runs out), they ask “how do I make the water around my house safe to drink?”

Here's how they're doing it.

Fill from the lake. Hang it. Clear water comes out the other end.

The System That Needs Nothing From the Grid

Creek Water Goes In the Top. Drinking Water Comes Out the Bottom.

Hartenwell gravity water filter kit: fill the bag, hang it, drink — FIG. 5 — Fill. Hang. Drink. Gravity does the work.

The Hartenwell Gravity Water Filter Kit turns a creek, a pond, a rain barrel or a bathtub into drinking water for your whole household at once. No power. No pump. No chemicals. No sucking on a straw.

Fill the one-gallon bag. Hook it on a branch, a nail, a cabinet handle. Gravity drives the water down the hose and through the filter core while your hands are busy with everything else. Drinking water runs out the bottom on its own.

The core is a 0.1-micron hollow-fiber membrane. Picture a bundle of microscopic straws with walls full of holes smaller than a bacterium. Water passes. Bacteria and parasites are physically too big to follow. No chemical, no tablet: a sieve they can't get through.

Removes 99.99% of bacteria, parasites and microplastics
A full gallon per fill — water for the family, not one sip
Works with no power. Hang it, gravity does the rest
Stores flat for years in a drawer or a car trunk

In the box: the gravity bag, the filter core, the hose, the hanging strap. Three steps: fill, hang, drink.

Every kit ships with 3 free preparedness guides (a $70 value): The Home Water Emergency Handbook, the Food & Water Storage Workbook and 16 Emergency Prep Checklists. Sent to your inbox the moment you order.

Pond in. Drinking water out.

Frequently Asked Questions

Why not a cheap filter straw?

A straw gives one person a hard-won mouthful, face down at the creek. The Hartenwell kit fills a gallon on its own while you do something else, and that gallon feeds the whole house: drinking, cooking, rinsing. One keeps a hiker going. The other keeps a family going.

Why not just boil water?

Because the notice to boil usually arrives when the stove is dead too. Boiling takes a working stove or fuel, a pot and twenty minutes per batch, and the moment you most need it is exactly the moment the stove is dead. It also does nothing for silt, sand or taste. The kit needs only gravity and starts working the moment you hang it. (When your utility tells you to boil, follow their instructions. The kit is for the hours and days when you can't.)

Does it take out viruses, or chemicals like lead?

No. We'd rather tell you than have you find out. A 0.1-micron hollow-fiber membrane stops bacteria, parasites and particles — the things that make creek, pond, rain and stored water dangerous in an emergency. It isn't made for chemical spills or lead plumbing.

Will it go bad sitting in a drawer?

It stores flat and dry for years in a drawer, a closet or a car trunk. One rule: never let the core freeze while it's wet. Dry it fully before you put it away.

Is it hard to use?

Fill, hang, open the valve. No pumping, no charging, no squeezing, so a child or a grandparent can run it alone.

How much water do I need to store anyway?

The federal guideline is one gallon per person per day, for several days. The kit doesn't replace that — it's what you use when the stored water runs out and the tap still isn't safe.

What if it isn't right for me?

You have 90 days. If it isn't what you expected, for any reason, return it and we refund you in full.
