On April 6, more than 40 members of the Calvert Hall and NDP Science National Honor Society chapters volunteered for the Gunpowder Valley Conservancy Project Clean Stream. This is an annual service project in which the students join together as part of the larger effort to keep the Chesapeake Watershed free of pollution. It was calculated that the group collected 1,000 pounds of trash and debris. Volunteers included 21 CHC students and 19 NDP students, along with the chapters moderators, Tom Peri ’71 (NDP moderator) and Mr. Charles Motsay ’76 (CHC moderator).
