More on Bottle Water Contamination

According to WebMD:

• In its test of 10 best-selling brands of bottled water, the Environmental Working Group (EWG) found mixtures of 38 different pollutants including bacteria, fertilizer, and industrial chemicals in some of the tested brands at levels that were similar to tap water.
  
• Samples of the Sam's Choice water purchased at a San Francisco area Wal-Mart had levels of the disinfection byproducts trihalomethanes that exceeded the California legal limit for these chemicals.
  
• Samples of Giant's Acadia brand water also had levels of the chemicals that exceeded California safety standards, although the brand was sold only in mid-Atlantic states, where it met standards.
  
• Samples of the Sam's Choice brand also had higher-than-allowed levels of the chemical bromodichloromethane, which is a known carcinogen.
