At EWG, our team of scientists, engineers, policy experts, lawyers and computer programmers pores over government data, legal documents, scientific studies and our own laboratory tests to expose threats to your health and the environment, and to find solutions. Our research brings to light unsettling facts that you have a right to know.

Thanks for your help! When you send us your labels, we'll send you a Shopper's Guide magnet. And if you're 1 of the top 3 people who sends the most labels, you'll win a 100% organic cotton shopping bag and a Klean Kanteen water bottle! Questions? Email Nneka.
While Environmental Working Group encourages you to drink filtered tap water, we do think it's important to study what's in bottled water.
