Every one of us, even unborn fetuses, are continually exposed to microplastics which have become such ubiquitous global environmental pollutants that they now contaminate the everyday air, food and water we take in.

Given a growing body of evidence that many chemicals in plastics pose human health risks, Californians should welcome recently passed legislation putting the state on path to be the first to track microplastics in tap water.

Because plastics are highly resistant to biodegradation – fragmenting instead into ever smaller bits eventually reaching micron and nanometer dimensions – they travel unseen in wind and waterways so that even the most remote regions of the globe, like the Arctic seabed and summit of Mount Everest, are contaminated with microplastics.

Global plastics production exceeded 360 million metric tons in 2019 and shows no signs of leveling off, so it’s no surprise microplastics (smaller than 5mm) are increasingly showing up in disturbing places like house dust, beer, table salt, indoor air, drinking water, seafood, plankton, and human poop.

Many constituents of plastics and the pollutants they pick up from the environment are known to be endocrine disruptors, carcinogens or developmental toxins which pose the greatest threat to developing fetuses. Bisphenol-A (BPA)) for example, a building block of certain plastics, was banned nationwide from use in baby bottles and sippy cups in 2012 because its mimicry of the hormone estrogen tampers with sexual development in both males and females. Fetal exposure to phthalates, chemical additives that render plastics soft and pliable, lowers sperm counts.

The placenta in humans has historically been viewed as a reliable barrier protecting the fetus from potential dangers lurking in the mother’s bloodstream. This fantasy has been shattered by shocking revelations in recent decades, like a 2005 report from Environmental Working Group that umbilical cord blood of U.S. babies contains an average of 200 industrial chemicals and pollutants.

Americans have grown suspicious of tap water quality, yet it’s doubtful many could name a single contaminant they imagine spewing from their faucets.  Blind faith once placed in the public water supply is being transferred to bottled water, even though the average citizen probably knows equally little about pollutants that might lurk there too.

Thanks to the non-profit organization Environmental Working Group (EWG) for creating the largest-ever national drinking water-quality database, most everyone now can read about the levels and health risks of specific pollutants found in their tap water.  Unfortunately, the news is not great overall.

EWG’s database covers 48,000 communities in 45 states and catalogues millions of water quality tests performed by water utilities between 2005 and 2009.

Among the nation’s most populous cities, Pensacola, FL, Riverside, CA and Las Vegas, NV were rated the worst for water quality, testing positive for between 33 and 39 different contaminants across five years.  Arlington, TX, Providence, RI and Fort Worth, TX ranked best with just four to seven pollutants each.  The national average was eight pollutants.
