Najwa Obeid worked as a water resources engineer for Parsons Brinckerhoff in
Boston, MA, from 2005 to 2008. At the same time, she was volunteering for the NGO
Engineers without Borders in the Dominican Republic, where she visited two water
treatment plants that used slow sand filters. At one plant, the phosphorus removed
from the treated water was being disposed of in a nearby river undergoing
eutrophication. The same river was used downstream as a water supply.
