Many people assume their tap water is safe because it's treated, or that bottled water is pristine. Unfortunately, both can harbor a surprising array of contaminants that can contribute to a "toxic buildup" impacting cellular function, hormone balance, gut health, and more.
Here are some of the toxic materials that could be lurking in your tap or bottled water:
Chlorine and Chloramine: These are used to disinfect public water supplies. While effective at killing pathogens, they can react with organic matter in water to form harmful disinfection byproducts (DBPs) like trihalomethanes (THMs) and haloacetic acids (HAAs). These DBPs are linked to increased risk of cancer and reproductive issues.
Lead: Often leaches into water from old lead pipes, fixtures, or solder. Even low levels of lead exposure can cause developmental problems in children, and neurological and kidney damage in adults.
Arsenic: A naturally occurring metalloid that can contaminate groundwater, arsenic exposure is linked to various cancers, skin lesions, and cardiovascular disease.
Fluoride: While added to some water supplies for dental health, excessive fluoride can have adverse effects, including skeletal fluorosis and potential neurological impacts.
Pesticides and Herbicides: Runoff from agricultural areas can introduce chemicals like atrazine, glyphosate, and 2,4-D into water sources. These can disrupt endocrine function and pose cancer risks.
Pharmaceuticals: Traces of medications (e.g., antidepressants, pain relievers, hormones) can enter the water supply through human waste and improper disposal, and current treatment methods don't always remove them completely. Their long-term effects on human health, even in trace amounts, are a growing concern.
Industrial Chemicals (e.g., VOCs, PFAS): Volatile Organic Compounds (VOCs) like benzene, trichloroethylene (TCE), and vinyl chloride can enter water from industrial spills or leaky underground storage tanks. Per- and polyfluoroalkyl substances (PFAS), known as "forever chemicals," are widely used in industrial applications and can contaminate water sources, persisting in the environment and the human body, linked to various health issues including cancer and immune system dysfunction.
Heavy Metals (other than lead): Cadmium, mercury, and chromium can enter water from industrial discharge or natural mineral deposits, leading to kidney damage, neurological disorders, and other chronic health problems.
Microplastics: Increasingly found in tap water, the long-term health effects of ingesting these tiny plastic particles are still under investigation, but they are a concern given their ability to absorb other toxins.
While often marketed as pure, bottled water isn't immune to issues:
Microplastics: A significant concern in bottled water due to plastic degradation from the bottles themselves. Studies have shown high levels of microplastic particles in many popular brands.
Phthalates and BPA (Bisphenol A): These endocrine-disrupting chemicals can leach into water from plastic bottles, especially when exposed to heat or sunlight. They are linked to hormonal imbalances, reproductive issues, and other health concerns.
Lack of Regulation: While tap water is regulated by the EPA, bottled water is regulated by the FDA, often with less stringent testing requirements, and frequency of testing can vary significantly. Some bottled waters are simply filtered tap water, and their source may not be as "pure" as advertised.
Variable Source Quality: The quality of "spring water" or "artesian water" can vary widely depending on the source and its surrounding environment, potentially picking up natural contaminants. (Look up the latest scandal with Perrier and Nestle in France!)
