The Hidden Dangers in Every Drop
Bad water doesn't just taste bad -- it damages your health, your home, your appliances, and your wallet. Explore the full scope of problems lurking in unfiltered water.
Cancer-Linked Contaminants
EWG's 2025 database found nearly 100 known or probable carcinogens in American tap water. Treating multiple contaminants simultaneously could prevent up to 50,000 lifetime cancer cases nationwide.
Chromium-6 in LA Water
The 'Erin Brockovich' contaminant is in LA tap water at 0.20 ppb -- ten times EWG's health guideline. Linked to stomach and gastrointestinal cancers. 264 million Americans are exposed.
Arsenic Exposure
A known carcinogen linked to bladder, lung, skin, and kidney cancers. The EPA's legal limit was set based on cost of removal -- not health safety. LA levels exceed EWG's 0.004 ppb guideline.
PFAS Forever Chemicals
CDC detected PFAS in 99% of Americans, including newborns. 177 California water systems serving 18.9 million people exceed EPA limits. Linked to kidney cancer, thyroid disease, and immune suppression.

What Our Customers Are Saying
“Water₂O completely transformed our home's water quality. The team tested our water, designed a custom system, and had it installed in just a few hours. The difference was immediate -- no more hard water stains, and the drinking water tastes incredible.”
Sarah & Mike T.
Pasadena, CA
“I've dealt with several water companies before and none come close to Water₂O. They actually test your water first instead of just selling you the most expensive system. Our system is perfectly sized for our home and the 12-year warranty gives us total peace of mind.”
James R.
Beverly Hills, CA
“What sold us was the 24/7 support. When we had a question at 9pm on a Saturday, Zeke responded within minutes by text. That level of care is unheard of. The water quality is outstanding and the system looks great in our garage.”
The Chen Family
Santa Monica, CA
“From the initial water test to the final installation, everything was professional and transparent. No pressure sales, just honest recommendations based on our actual water conditions. Our skin feels softer, clothes are brighter, and we stopped buying bottled water.”
Maria G.
Calabasas, CA
“We chose Water₂O because they use USA-made components and offer a real warranty -- not the fine-print kind. The installation was clean and fast, and the post-install water test showed exactly what they promised. Highly recommend.”

“Best investment we've made for our home. The reverse osmosis water tastes better than any bottled water we've bought. Installation was quick, the team was respectful of our home, and the follow-up testing proved the system works perfectly.”
Robert K.
Altadena, CA
“We had terrible hard water that was destroying our appliances. Water₂O tested our water, showed us exactly what was wrong, and designed a complete system. Three months later, our water heater is working better and our dishes come out spotless.”
The Martinez Family
Corona, CA
“Zeke is genuinely passionate about water quality. He spent an hour explaining our test results and never once pressured us. The softener system he designed has made a huge difference -- our hair and skin feel amazing, and the water spots on our shower glass are gone.”
Amanda S.
Palos Verdes, CA
“After years of dealing with hard water stains and dry skin, we finally called Water₂O. The difference is night and day. Our plumber even noticed less buildup in our pipes during a recent visit. The system paid for itself in peace of mind alone.”
Patricia & Tom W.
Calabasas, CA
“We were skeptical at first, but the free water test opened our eyes to what was actually in our tap water. Water₂O recommended exactly what we needed -- nothing more, nothing less. Six months in and we couldn't be happier with the results.”
