Hello, Dr. Metcalf continues to mentor Tom Carter, Director of Aqua Pura Para El Pueblo, a group that also works internationally teaching basic water quality testing for coliforms and distributes simple pasteurization indicators made from a wax that melts at 65 C. These indicators have the potential to save much fuel for those folks that are currently boiling water to ensure having reached adequate temperature for pasteurization. Kind regards, Jeff Holiman
