Many bottled water companies use polycarbonate plastic for their 3- and 5-gallon water cooler bottles. Many international studies have been conducted to assess the potential for trace levels of BPA to migrate from lined cans or polycarbonate bottles into foods or beverages. The water samples from two of HDPE bottles were estimated to contained concentrations of BPA significantly above the theoretical mean for the 0.05 ng/ml detection limit of the assay (bottle no.1 p=0.049; bottle no. 2 p=0.046 as calculated using a one sample t-test). The toxicity level in drinking water and human exposure via drinking water is a matter of concern, particularly when halogenated disinfection such as chlorination and bromination are commonly used . The bottled water industry promotes an image of purity, but comprehensive testing by the Environmental Working Group (EWG) reveals a surprising array of chemical contaminants in every bottled water brand analyzed, including toxic byproducts of chlorination in Walmart's Sam's Choice and Giant Supermarket's Acadia brands, at levels no different than .
