Water
We all drink water – whether it’s from the tap, from a well, or bottled water. However, did you know that chemicals linked to breast cancer have been detected in various types of drinking water?
In general, tap water is cleaner than plastic bottled water, which can leach chemicals that interfere with our hormones. However, even treated tap water can contain chemicals that may impact your health.

Science: Water and breast cancer
There are many different contaminants that can enter our water systems. Water utilities are required by law to treat the water to remove dirt, metals, certain chemicals, viruses, and bacteria before it reaches our home. Some chemicals found in tap water, like PFAS, arsenic, lead, pesticides, and phthalates, are harmful to our health, but the U.S. Environmental Protection Agency (EPA) does not regulate all toxic chemicals.
Tap water study
In a UC Davis Study of water contaminants across California, many endocrine disrupting chemicals were found almost exclusively in bottled water. Study findings
What’s happening in policy
Plastic bottles can leach harmful chemicals into water. A 2024 California bill, Reducing Toxics in Packaging Act of 2024 (CA AB 2761 – Hart) would remove PFAS and PVC, two very toxic substances, from packaging. Californians: Take Action Now for Safe Drinking Water!
