Most people assume that if their water meets government regulations, it must be safe. But legal doesn’t always mean healthy.
Water treatment standards are outdated, and many harmful contaminants aren’t fully regulated. Just because your city allows certain levels of chemicals and metals doesn’t mean they’re safe for long-term exposure.
What’s Allowed in “Legal” Water?
🚱 PFAS ("Forever Chemicals") – The EPA only recently started limiting PFAS, but many cities still have levels that exceed what health experts recommend. These chemicals have been linked to cancer, immune disorders, and fertility issues.
🚱 Lead – No Safe Level – The EPA’s “action level” for lead is 15 parts per billion (ppb), but medical experts say even 1 ppb can cause brain damage in children.
🚱 Chlorine & Disinfection Byproducts – Cities use chlorine to disinfect water, but it reacts with organic material to form trihalomethanes (THMs), which have been linked to cancer.
🚱 Arsenic & Heavy Metals – The legal limit for arsenic is 10 ppb, but studies show even 5 ppb can increase cancer risk.
Why Legal Limits Aren’t Enough
✔ Regulations are outdated – Many water safety laws haven’t been updated in decades, and new contaminants aren’t always tested for.
✔ Testing doesn’t catch everything – Water quality can change between tests, meaning contamination can go undetected.
✔ Household plumbing adds risks – Even if city water is “safe,” lead pipes and aging plumbing in homes can introduce new contaminants.
The Only Real Solution: Home Filtration
The best way to ensure truly safe water is to filter it before it reaches your tap.
💧 Reverse osmosis removes PFAS, lead, and heavy metals for ultra-clean drinking water.
🚿 Whole-home filtration eliminates chlorine, sediment, and bacteria for healthier water throughout your home.
🛁 Water softeners prevent mineral buildup, protecting pipes and appliances.
