Contaminants in Your Water
0 Exceed EWG Guidelines
0 Total Contaminants
01. "Legal" Does Not Mean Safe
Federal legal limits for water contaminants were set decades ago and are often 10x to 100x higher than what scientists now consider safe.
02. The EWG Health Guidelines
The Environmental Working Group (EWG) establishes stricter health guidelines based on the latest peer-reviewed science—not outdated regulations.
03. Why This Matters
Your report compares your local water quality against EWG guidelines to show which contaminants exceed levels considered safe for long-term health.
Top 4 Contaminants in Your Tap Water
Health Risks Linked To Contaminants In Your Local Water Source:
Cancer
A 2025 USC Keck School of Medicine study found communities with PFAS-contaminated water experience up to 33% higher rates of certain cancers. Separately, NIH research links chlorination byproducts to approximately 13,000 bladder and rectal cancer cases annually in the US.
Fertility Issues
Mount Sinai researchers found PFAS exposure can reduce women's fertility by up to 40%. A Minnesota study of nearly 50,000 births showed PFAS-contaminated water increased premature births by 45% and low birth weight by 36% before filtration was installed.
Child Development
The EPA reports 1 in 6 US children are affected by developmental disabilities linked to environmental exposures. A University of Maine study found children drinking well water with elevated arsenic showed significant reductions in IQ, working memory, and verbal comprehension.
Hormone Disruption
NIH research identifies multiple endocrine-disrupting chemicals in tap water including BPA, phthalates, and pesticide residues. Studies show PFOA and PFOS exposure impairs reproductive hormone function, while common herbicides interfere with thyroid hormone production.
Cosmetic Issues
Research published in the Journal of Allergy and Clinical Immunology found chlorinated tap water is associated with a 33% higher risk of eczema in children. The National Eczema Association confirms hard water minerals damage the skin barrier, causing dryness, irritation, and flare-ups.
Organ Damage
A Nature Scientific Reports study found that combinations of heavy metals, fluoride, and water hardness cause severe kidney damage—even at WHO-approved levels. The EPA confirms arsenic exposure is linked to liver and kidney damage, while PFAS compounds accumulate in these organs over time.
