The centerpiece of the mission was drilling a new well in Alyet Village, whose residents previously had to walk five kilometers to the nearest water source. And that water carried diseases including typhoid fever, yellow fever and hepatitis, as well as causing diarrhea that was all too often fatal.
"In the states, we don't usually take diarrhea that seriously, because we have access to medicine and we drink clean water," Olsen notes. "But it's one of the biggest killers of children under five in the developing world."
