1st Lt. Sarah Plantamura, a project engineer assigned to the U.S. Army Corps of Engineers Baltimore District Fort Meade office from Minnesota, examines water treatment operations at the Washington Aqueduct's Dalecarlia Water Treatment Plant in Washington, D.C., Jan. 30, 2026, during an Army Leader Professional Development event. Lt. Col. Mark Pollak, Deputy District Engineer for USACE Baltimore District, led seven uniformed military officers through the historic facility in a structured training designed to build competent, character-driven leaders through education, training, and experience. The group included Capt. Sam McAvoy, Royal Engineers, from Warrington, England, who is completing a nine-month industrial placement with USACE Baltimore District. Trina Littlejohn, chief of staff at the Washington Aqueduct, guided participants through the complete water treatment process from Potomac River intake through chemical treatment, sedimentation, and filtration to the clear basins that distribute drinking water to the greater Washington, D.C., area. The LPD event exposed officers from project management, engineering, real estate, and headquarters divisions to the strategically important facility's operations, highlighting the intricate chemical treatment processes that ensure safe, high-quality drinking water for millions in the nation's capital.
