Linda Powers spent part of her summer biking around Tanzania testing wells for bacteria using a unique instrument designed at the UA. As you know, I am obsessed with the fact that 1.5 billion people go without clean water every day. You are not going to believe what she and doctoral student Aminata Kilung accomplished as they were out cycling and testing for as much as 15 hours a day. In this case, hearing will be believing because I doubt this kind of excursion is in my future, but one never knows. Again, can’t wait. This show sponsored by Goodwill Industries of Southern Arizona.
