Since 2012, graduate students from the Water: Systems, Science and Society Program at Tufts University have been working in Bethlehem to develop and maintain water quality monitoring programs in Palestinian communities. Last year, together with the Najee Center (a Palestinian NGO in the Aida refugee camp) and 1for3 (an American NGO that addresses environmental health and quality of life issues in Palestinian communities), they started a water quality monitoring and education program in Al-Walaja village.
