Switch to tap water !  There’s very little evidence that bottled water is any safer, as tap water must meet stricter federal and local standards for chemical contaminants. Furthermore, drinking tap water helps eliminate the waste associated with single-use plastic bottles, only 10 percent of which are recycled each year. If you’re concerned about water quality, buy a reusable bottle, and invest in a tap-water filters that eliminate lead, which can leach into water from decaying pipes, and chlorine, often added to sanitize water and eliminate bacteria. Filters generate less waste than bottles. Source - http://www.thegreenguide.com
