ERDC researcher joins State Department delegation to Botswana
A small portion of the flooded Okavango Delta is shown where the water is clear for about a foot or more. Locals claim this water is so clean that a person can drink directly from it. Dr. Mark Chappell, U.S. Army Engineer Research and Development Center (ERDC) senior research physical scientist, traveled to Botswana with a team to assess opportunities for supporting water management and water security in the country’s Okavango Delta Region.
