Julia Phelan talked to the students about the solutions for clean water they are bringing to rural Alaska. CampWater Industries, a local Delta Junction company produces filtration systems that are used worldwide.

Students then  mixed up a batch of really dirty water and they got to try various materials to make water filters.  Last of all, she showed them the filtration system being used in the Alaskan villages, and they got to pump some water through it using a hand crank.
