What's in Martha's Vineyard's Water?
Martha's Vineyard serves approximately 17,000 residents (peak season). Water source: Island aquifer.
Why Cape Cod Has PFAS Problems
Joint Base Cape Cod (formerly Otis Air Force Base) used PFAS-containing firefighting foam for decades. These "forever chemicals" have contaminated the region's sole-source aquifer, affecting drinking water across the Cape.
Limited freshwater source
Detected in Martha's Vineyard water. RO filtration removes 99%+.
Nitrates

Saltwater intrusion risk
Detected in Martha's Vineyard water. RO filtration removes 99%+.
PFAS Health Risks
PFAS (Per- and Polyfluoroalkyl Substances) are linked to:
- • Cancer: Kidney, testicular, and other cancers
- • Thyroid disease: Hormone disruption
- • Immune suppression: Reduced vaccine effectiveness
- • Reproductive issues: Fertility problems, developmental delays
- • Liver damage: Elevated cholesterol, liver enzyme changes
Note: PFAS don't break down in the environment or your body — hence "forever chemicals."
The Solution: Reverse Osmosis Removes 99%+ of PFAS
Standard carbon filters reduce but don't eliminate PFAS. Reverse Osmosis is the gold standard for PFAS removal.
Frequently Asked Questions
Why is Cape Cod water contaminated with PFAS?
Joint Base Cape Cod used AFFF (aqueous film-forming foam) containing PFAS for firefighting training for decades. These chemicals leached into the sole-source aquifer that supplies drinking water to the entire Cape.
Is bottled water safer than Martha's Vineyard tap water?
Not necessarily. Many bottled waters also contain PFAS. A home RO system is more reliable and cost-effective long-term.
Should I get my water tested?
Testing can confirm PFAS levels, but given regional contamination, installing an RO system is prudent regardless of test results.
