The documentary "Tapped" will bring its "Get Off the Bottle Tour" to the University of Colorado on Wednesday night to raise awareness about the bottled water industry.

"Every day, 30 million single-serve bottles end up in the land fill and a lot of the time our recyclables are being exported to other countries because we don't have the capacity to recycle all of them," said Stephanie Soechtig, the director of "Tapped."

A half-hour before the 6 p.m. screening, Soechtig and producer Sarah Olson will collect plastic water bottles and exchange them for Klean Kanteen bottles. The empty plastic containers will be thrown in a clear recycling compartment on the back of their touring vehicle with the goal of filling it up by the time they reach New York on Earth Day, April 22.

The tour began in Los Angeles and will stop in 21 other cities to collect bottles and screen the film. "Tapped" explores the bottled water industry and how it has created a commodity out of water and its dependence on oil. The film also investigates harmful plastic additives such as the chemical known as PET and Bisphenol-A (BPA).

"You are led to believe that you are getting a pure product that is safer than tap water," said Soechtig. "But what you are really getting in the case of BPA is a chemical that was originally invented as a synthetic estrogen, so you aren't getting a clean product."

Each year, approximately 1 million pounds of BPA end up in the environment, according to the Environmental Protection Agency.

The EPA announced Monday that its investigation of BPA will start measuring levels in drinking and ground water due to concerns about its effects on infant growth and development. The EPA's decision follows a statement by the Food and Drug Administration in January that it has some concern about the chemical's effects on the brain, behavior and prostate gland in babies and young children.

"The bottled water industry is a microcosm of other issues in this county such as a lack of regulation of products we consume," Soechtig said. "We need to be more aware of things we buy and be your own advocates."
