The jury is still out.
A recent high-profile lawsuit against the Nalgene Company has brought water bottles into the spotlight in terms of their link to cancer. An Iowa woman sued that company after she developed two rare cancers, which she claims were caused by her habit of drinking water from a Nalgene bottle filled with tap water. Plaintiffs’ attorneys assert that when heated, something about these containers releases chemicals which act like estrogen in the body and affect hormone levels to increase breast cancer risk.
