PFAS and pregnancy: what Houston parents should know about drinking water
I’m writing this at 6 months pregnant and if you’re expecting, you know… pregnancy changes how you look at EVERYTHING.
How many times have you googled “can I eat __?” in the last week..
Yup, me too.
A zillion.
So I get why you’re thinking about your water. It’s the #1 thing that goes into your body everyday and you’re probably trying to consume more of it than every before just to stay hydrated.
I’m guessing you’ve even googled...
Should I be concerned about PFAS exposure during pregnancy?
Understanding what PFAS are, why pregnancy is a sensitive window, and how families reduce exposure can help you make confident, informed decisions.
We never want to elicit fear, please continue reading with a lens of education and making the best decision for your family.
What are PFAS and why are they a concern?
PFAS (per- and polyfluoroalkyl substances) are a large group of man-made chemicals used for decades in products designed to resist heat, oil, stains, and water.
They’re often called “forever chemicals” because:
They do not break down easily
They persist in water and soil
They accumulate in the human body over time
PFAS enter water supplies through industrial activity, firefighting foams, landfills, and wastewater runoff. Once present, they are difficult to remove using standard municipal treatment.
Why pregnancy is a sensitive period for PFAS exposure:
During pregnancy, the body undergoes complex hormonal and developmental changes. Research indicates that PFAS can cross the placenta, meaning exposure may affect both the parent and the developing baby.
Health agencies have associated PFAS exposure with:
Hormonal and endocrine disruption
Effects on fetal growth and development
Changes in immune system development
Potential impacts on birth outcomes with long-term exposure
Because PFAS accumulate, even low-level exposure over time can be meaningful, especially during pregnancy.
How PFAS exposure can occur at home:
For pregnant individuals, PFAS exposure may come from:
Drinking tap water
Cooking with unfiltered water
Washing produce
Making beverages like tea or coffee
Daily hydration needs
Importantly, boiling water does not remove PFAS. In some cases, it can slightly concentrate them.
That’s why families often focus on improving drinking and cooking water first.
What Houston parents should know about local water:
Houston’s municipal water meets regulatory standards, but PFAS regulations are still evolving. Testing frequency and PFAS types vary by location, and allowable limits continue to change as science advances.
Many expecting parents choose to:
Test their home’s water directly
Reduce PFAS exposure where practical
Use precautionary filtration during pregnancy
This approach is about minimizing unnecessary exposure — not reacting to an emergency.
What actually removes PFAS from drinking water:
Not all filters are effective against PFAS.
The most reliable household treatment methods include:
Reverse osmosis (RO)
High-quality activated carbon systems designed for PFAS reduction
Reverse osmosis is widely recognized because it removes contaminants at the molecular level, including many PFAS compounds.
Why reverse osmosis is often chosen during pregnancy:
Reverse osmosis systems are commonly installed at the kitchen sink, where drinking and cooking water is used most.
Parents choose RO because it:
Reduces PFAS and other dissolved contaminants
Improves overall water purity
Provides consistent water quality
Supports peace of mind during pregnancy
For many families, this is a long-term upgrade focused on health during an important life stage.
