The Delaware River Watershed Initiative: Improving Water Quality, Involving 50+ NGOs and Building on Sound Science

Nathan Boon,

William Penn Foundation

Stefanie Kroll, PhD

Academy of Natural Sciences

Abstract:  The Delaware River Watershed Initiative takes a strategic, targeted, scientific approach to improving water quality through work at the land-water interface.  The Initiative, kick-started by the William Penn Foundation, targets subwatershed “clusters” with potential for restoration or preservation in order to effect water quality improvements.  This program is composed of many unique features, one of which is monitoring and assessment of aquatic ecosystems to measure effectiveness of the on-the-ground actions. This integrated approach will be used to model outcomes and to evaluate ecosystem response in the short- and long-terms. In addition, the Academy is forming a team to develop a research agenda for the basin.  The objective of this work is to provide information on the effectiveness of specific conservation strategies, scale up these efforts across the watershed and to contribute to collaboration, research and investment in restoring and protecting water quality within our region. 

As a Program Officer with the William Penn Foundation, Nathan Boon supports science and data-driven approaches to protect and restore the Delaware River Watershed - drinking water source for 17 million from New York City to  Philadelphia, Trenton, and Wilmington. Nathan was previously imbedded in francophone Cameroon with the 501 (c)(3) nonprofit Breaking Ground, engaged with a local municipality in water quality analysis and health impact assessment. Nathan's nonprofit experience also includes time as a board member with the American Water Resources Association, National Capital Region Section and membership with the American Public Health Association, Environment Section.


Nathan holds Bachelor's and Master's degrees in Earth and Environmental Science from Wesleyan University and a graduate certificate in Environmental Science, Health and Policy from the George Washington University School of Public Health. Before joining the Foundation in 2012, Nathan worked with the management consulting firm Booz Allen Hamilton. He is a certified Project Management Professional and Geographic Information Systems Professional

Stefanie Kroll's work focuses on using aquatic insects and other indicators to examine the impacts of human activities on aquatic ecosystems.  Stefanie is the Project Science Director for the Delaware River Watershed Initiative at the Academy of Natural Sciences.  She has a PhD in ecology from SUNY College of Environmental Science and Forestry in Syracuse, NY and a master's-equivalent on ecology of arid watersheds at the University of Castilla-La Mancha in Albacete, Spain. She did her post-doctoral work in the Department of Entomology at Cornell University. Dr. Kroll is currently an adjunct faculty member at Drexel University and has taught at Onondaga Community College and Colgate University. She worked in interpretation and translation and taught English as a foreign language for over a decade. Stefanie is on the monitoring advisory committee of the Raritan Headwaters Association and works with ANS' Women In Natural Sciences (WINS) program. Other research interests include aquatic insects and climate change, the ecology of Onondaga Lake (an ecosystem recovering from extensive pollution) and stream ecosystem dynamics in arid landscapes.  She also worked for several years in forest inventory and providing program support for a nonprofit environmental organization.
