The Ohio River Foundation (ORF) is an effective nonprofit with a 25-year track record of delivering hands-on education and conservation programs. ORF is the only citizen group dedicated to protection and restoration of the Ohio River and its 25-million-person watershed that covers 200,000 square miles. Its work is vital as more than a million people depend on the Ohio River as their primary source of drinking water. A gift from the Pfau Foundation will support the River Explorer and Mussels in the Classroom Access Fund.
