What’s Really in Your Tap Water — And Why Millions Are Switching
What contaminants are in tap water? Most US tap water legally meets federal safety standards, but it can still contain chlorine, chloramines, lead from aging pipes, PFAS “forever chemicals,” microplastics, and disinfection byproducts. The quality varies dramatically by city, infrastructure age, and source water. Millions of households are switching to alternative water sources as awareness of these issues grows.
What Tap Water Contaminants Are Most Common Across the US?
The US Environmental Protection Agency (EPA) regulates over 90 contaminants in public water supplies under the Safe Drinking Water Act. Meeting the legal standard does not mean your water is optimal for health — it means it is within permitted limits. Here are the most widespread issues:
- Chlorine and chloramines — Used as disinfectants but react with organic matter to form trihalomethanes (THMs), which have been linked to bladder cancer risk in long-term exposure studies.
- Lead — The EPA estimates approximately 9 million lead service lines still deliver water to US homes. Lead has no safe exposure level, particularly for children.
- PFAS “forever chemicals” — Per- and polyfluoroalkyl substances detected in water supplies serving over 200 million Americans. They accumulate in the body over time and are associated with immune disruption, thyroid issues, and certain cancers.
- Microplastics — A 2020 study found microplastics in 93% of tap water samples tested globally. The long-term health implications are still being studied.
- Agricultural runoff — Nitrates, pesticides, and herbicides from farming can contaminate groundwater sources and surface water intakes in rural and suburban areas.
How Does Tap Water Quality Vary by Location?
Water quality is highly localized. Two cities supplied by the same river can deliver significantly different water depending on their treatment infrastructure, pipe age, and local industrial history. The Environmental Working Group (EWG) Tap Water Database covers over 48,000 utilities and consistently finds that while most water is legally compliant, it contains detectable levels of dozens of chemicals at concentrations that exceed health guidelines (which are stricter than legal limits).
★ Important Distinction“Meeting EPA standards means your water is legal — not that it’s optimal. The EPA’s maximum contaminant levels are set based on what is technically and economically feasible to remove, not solely on what science says is safe. Health-protective thresholds are often significantly lower.”
Skip the Pipe Entirely
The Kara Pure 2 makes water from air — bypassing municipal pipes, aging infrastructure, and plastic bottles entirely. 10 liters of pure, alkaline water daily.

Consumer awareness of water quality issues has accelerated sharply since the Flint, Michigan lead crisis brought municipal water safety into national focus. The CDC reports rising rates of home water filtration adoption, and market research consistently shows water quality as a top household concern.
But not all alternatives solve the problem. Many consumers switch to bottled water, only to discover it carries its own risks: a 2018 study by Orb Media found microplastics in 93% of bottled water brands tested. Point-of-use filters help but must be maintained and cannot address all contaminant classes.
How the Kara Pure 2 Solves the Tap Water Problem at Its Source
The most elegant solution to tap water contamination is not to filter tap water — it is to bypass it entirely. The Kara Pure 2 makes water from atmospheric air, meaning it has no exposure to municipal pipes, lead service lines, agricultural runoff, or PFAS-contaminated groundwater.
Its multi-stage purification then removes any airborne contaminants that might enter during the generation process, adds six essential minerals, boosts alkalinity to 9.2 pH, and UV-sterilizes every pour. The result is water that is not just clean — it is better than clean.
