If you have children in Durham, this article is for you. PFAS forever chemicals have been detected in Durham's drinking water — and while the city has a plan to fix it, that plan doesn't finish until 2029. Here is everything a Durham parent needs to know.
What Are PFAS?
PFAS stands for per- and polyfluoroalkyl substances. They are a family of over 12,000 synthetic chemicals that were invented in the 1940s and went on to be used in thousands of consumer and industrial products — Teflon cookware, Scotchgard fabric protectors, food packaging, firefighting foam (AFFF), waterproof clothing, dental floss, cosmetics, and more.
They are called "forever chemicals" for a specific reason: the bond between carbon and fluorine — the bond that makes PFAS so durable and water-resistant — is one of the strongest bonds in all of chemistry. It does not break down in sunlight. It does not break down in soil. It does not break down in water treatment. And critically: it does not break down in the human body.
⚠️ Durham Specific: Where Are PFAS Coming From?
Durham draws water from the Neuse River watershed. North Carolina has a well-documented PFAS contamination history tied to Chemours' manufacturing plant on the Cape Fear River (which discharges GenX and other PFAS compounds). While Durham's source water is not the Cape Fear, PFAS contamination has spread broadly across North Carolina's water systems. Durham has confirmed PFAS in its treated drinking water and is spending $15 million to address it.
Why PFAS Are Especially Dangerous for Children
Adults have developed immune systems, completed neurological development, and have larger body mass to dilute exposure. Children have none of these protections. Here is what the research specifically shows about PFAS exposure in children:
1. Disrupted Immune Development
Multiple peer-reviewed studies have found that children with higher blood PFAS levels show significantly reduced immune responses to vaccines. The Faroe Islands birth cohort study — one of the most significant PFAS health studies ever conducted — found that children with PFAS exposure had antibody concentrations up to 50% lower than unexposed peers after diphtheria and tetanus vaccination. The vaccines were less effective because PFAS had suppressed immune development.
2. Thyroid Disruption
The thyroid gland is essential for growth, metabolism, brain development, and hormone regulation. PFAS are endocrine disruptors — they interfere with thyroid hormone signaling. In children, whose brains are still developing, thyroid disruption during critical developmental windows can cause permanent cognitive impairment. Studies have linked childhood PFAS exposure to lower IQ scores and behavioral problems.
3. Early Puberty in Girls
Higher PFAS exposure has been linked to earlier onset of puberty in girls — specifically, earlier first menstruation (menarche). Early puberty is associated with increased lifetime risk of breast cancer, reproductive health issues, and psychological harm. The mechanism appears to be PFAS interference with estrogen signaling.
4. Developmental Delays
Prenatal PFAS exposure — during pregnancy — is associated with lower birth weight, reduced head circumference, and delayed developmental milestones. PFAS cross the placental barrier freely. A developing fetus cannot choose whether to be exposed; exposure is entirely determined by what the mother drinks.
What Durham's City Data Says
Durham began voluntarily testing for PFAS in 2018 — ahead of most utilities. Results have consistently shown PFAS presence in treated drinking water, with some compounds approaching or exceeding the new EPA maximum contaminant levels (MCLs) of 4 parts per trillion for PFOA and PFOS.
The city's response has been transparent: Durham has publicly shared its monitoring data, held community meetings, and commissioned the $15 million powdered activated carbon (PAC) upgrade. This is commendable. But the upgrade completion date of 2029 means Durham families are currently consuming water that, by the EPA's own new health-based standards, contains concerning levels of PFAS.
What Should Durham Parents Do Right Now?
The good news: protecting your children from PFAS in drinking water is not complicated or expensive. Here are the steps we recommend, in priority order:
- Step 1: Stop making infant formula with unfiltered Durham tap water. Formula concentrates exposure because it's 100% water-based. Use a PFAS-certified filter or bottled water (from a verified clean source) for formula until you have a proper filter installed.
- Step 2: Get a reverse osmosis (RO) filter installed at your kitchen tap. RO is the gold standard for PFAS removal — 99.9% reduction. A professionally installed under-sink RO system costs $800–$2,500. A DIY unit from Amazon (NSF/ANSI 58 certified) runs $150–$200. Either protects your drinking and cooking water effectively.
- Step 3: Replace your filter pitchers. Standard Brita and PUR pitchers do not remove PFAS effectively. Look for pitchers specifically rated for PFAS removal.
- Step 4: Get a whole-home or shower filter for chlorine removal. Chlorine and chloramines absorb through skin in the shower. For children who bathe daily, a shower filter that removes chlorine reduces a separate but real exposure pathway.
One more thing: Don't let perfect be the enemy of good. An imperfect filter installed today protects your child better than a perfect filter you're still researching in six months. Start with the drinking water. Everything else can follow.
Frequently Asked Questions from Durham Parents
Q: My child has been drinking Durham tap water for years. Should I be worried?
PFAS accumulate over time, but the body also slowly excretes them — with a half-life of roughly 3–8 years for different compounds. Your first step is to reduce ongoing exposure by filtering your water. Long-term health monitoring with your pediatrician is reasonable if you have specific concerns. Avoid panic — but do act.
Q: Does boiling the water remove PFAS?
No. Boiling does not remove PFAS. It can actually concentrate them by reducing water volume while PFAS remains. Boiling is not a solution for PFAS contamination.
Q: What about bottled water?
Some bottled water brands have been found to contain PFAS. If you use bottled water as a temporary measure, look for brands that publish their independent testing results. Long-term, a certified home filter is safer and dramatically cheaper than bottled water.
