I’m a mom of two (wildly energetic) boys, and I used to assume tap water was safe—just like you might. But after I started digging into what’s actually in our water, things changed.
Here’s why I no longer let my kids bathe in unfiltered tap water—and how I ensure their water is as safe as possible.
1. From Pond to Faucet — Your Water Isn’t Always “Clean”
So, where does our water come from?
It didn’t just magically appear in your kitchen sink or the tub. Most of our tap water starts its journey in nature — in rivers, lakes, reservoirs, or deep underground wells. These sources are often open to everything around them:
☠️ Pesticides from nearby farms
🏭 Chemical waste from factories
🚗 Oil, road runoff, and microplastics after storms
💊 Even leftover medications that people flush down their toilets
Once that water is collected, it gets sent to a municipal water treatment plant.
2. Treatment Plants Use Chemicals That Create Byproducts
Yes, plants add chlorine to kill unsafe bacteria—and that’s good because none of us want E. coli in our baths. However, chlorine can react with naturally occurring substances in the water to form byproducts, such as:
- Trihalomethanes (THMs)
- Haloacetic Acids (HAAs)
- Chlorite
These chemical byproducts have been linked to cancer, reproductive issues, and developmental problems, especially for babies, children, and pregnant women. These byproducts are linked to reproductive problems and even cancer.
After treatment, that water travels through miles of old pipes—some of which may be corroded, contaminated, or even made of lead—before finally reaching your home.
This matters, especially when it’s your toddler splashing in that tub!
3. Toxins That Should Never Be There—But Are
I had no idea just how many harmful chemicals could be hiding in something as basic as tap water. From heavy metals to hormone disruptors, here are some of the most common contaminants found in unfiltered tap water — and why they’re especially risky for our kids.
Lead is a toxic metal that can leach from old pipes. Even tiny amounts can damage your child’s brain and nervous system.
PFAS (Forever Chemicals) are man-made chemicals found in nonstick pans and waterproof clothes that build up in the body and are linked to cancer, thyroid issues, and hormone disruption.
Arsenic is a naturally occurring metal in groundwater that’s been linked to cancer, developmental delays, and skin problems.
Nitrates are often found in fertilizer runoff, especially dangerous for babies, where they can interfere with oxygen in their blood (“blue baby syndrome”).
Fluoride is added to water for dental health, but excessive intake can cause tooth discoloration, bone issues, and may impact brain development in young children.
Chlorine & Byproducts (THMs) are used to disinfect water, but they can form harmful byproducts like trihalomethanes (THMs) that are linked to cancer and reproductive issues.
Manganese is naturally present in some water systems. High levels can impact memory, behavior, and attention in young children.
VOCs (like benzene, 1,4-dioxane) are industrial chemicals that sneak into water from factories and landfills. Some are known to cause cancer and liver/kidney damage.
Pharmaceuticals (hormones, antibiotics) are trace amounts of medications that are flushed into water systems, which may interfere with hormones and increase antibiotic resistance.
Microplastics are tiny plastic particles from bottles, clothing, and packaging that can accumulate in the body and potentially disrupt hormone function.
Uranium or Radium, naturally found in some groundwater, are radioactive and increase the risk of cancer and kidney damage.
Pesticides & Herbicides are chemicals used in farming that often run off into water supplies. Many are hormone disruptors and linked to birth defects and cancer.
4. Kids Absorb More—And Detox Less
Here’s the part that got me: my boys are more exposed than me.
They drink more water per pound, soak in it for longer, and their skin soaks up more chemicals, especially during warm baths.
And their livers and kidneys are still developing, so they’re not as good at flushing toxins out as adults are.
5. “Legal” Doesn’t Always Mean Safe — And That’s the Scariest Part
You might assume that if our tap water passes federal safety tests, it must be safe — but here’s the truth:
Most legal limits for water contaminants haven’t been updated in over 20 years.
That means what’s “allowed” in your water today might be way above what health experts now consider safe, especially for babies and young kids.
Meanwhile, large industries are dumping chemicals (such as PFAS and pesticides) into our water sources, and water treatment plants aren’t equipped to remove all of them.
The system is broken — and it’s families like ours who pay the price. That’s why I stopped waiting for someone else to protect my kids and started filtering our water myself.
Because clean water shouldn’t be a luxury — it should be a basic right.
What You Can Do Today
- Check your water report on EWG.org or get your CCR (annual report from the city).
- See which chemicals are in your tap water.
- Choose certified filters that remove the contaminants found in your water.
- Don’t stop at drinking water—filter your bath/glass/skin-contact water, too.
- Start small. One filter now is better than none at all.
