The City of Portsmouth, New Hampshire hosted a meeting of the Municipal Alliance for Adaptive Management (MAM) on February 6, 2026, focusing on collaborative efforts to reduce nitrogen pollution in the Great Bay Estuary. The meeting included representatives from multiple municipalities, environmental organizations, consultants, and regulatory agencies. Key discussions centered on the progress of nitrogen reduction initiatives, including wastewater treatment plant upgrades and non-point source pollution controls, supported by over $2 million in research and monitoring funding. The group reviewed data tracking and accounting programs (PTAP) used to monitor pollutant reductions, emphasizing the importance of accurate data entry and inter-municipal collaboration to optimize reporting and compliance. Challenges faced by smaller communities in data management and resource constraints were acknowledged, with plans to provide additional training and support. The meeting also highlighted the positive impact of adaptive management approaches and the need for continued coordination among stakeholders to sustain water quality improvements in the estuary.
