Unsafe levels of toxic chemicals found in drinking water for 6M Americans
A small PSA: "Brita" brand water filters seem to be very popular in US, but they're also some of the worst in tests.  For example in this test ...http://www.goodhousekeeping.com/health-products/g684/water-f...?... "Brita" filters were found to remove around 55% of PFOA, whereas "ZeroWater" filters remove more than 95%.  I.e. "Brita" filters leave 9x more stuff in the water.  The performance difference is similar for other unwanted stuff, like lead.
