What’s in your drinking water?

Hawaii’s tap water contains more contaminants than you may realize: known carcinogens, heavy metals such as Arsenic and Chromium Hexavalent (Hex6)...and in Honolulu this includes 88x the safe limit of toxic Hex6, the poison that Erin Brockovich exposed in 1996. (95x on the west side!) Highlighted in orange are those NOT filtered out by standard carbon filters.

Some with high risk factors are highlighted with orange borders.
