Ted discusses his organization’s mission to protect and restore the massive Lower Susquehanna watershed spanning Pennsylvania and Maryland. He explains that his role involves advocacy, legal action, and water quality monitoring to combat pollution from industrial sources, hydroelectric dams, and agricultural runoff. Ted emphasizes that clean water is a fundamental right and highlights the alarming fact that 90% of Lancaster County's waterways are currently impaired. The conversation outlines how residents can support these efforts through membership and community science programs, such as reporting sick fish or monitoring bacteria levels. Ultimately, the source serves as an urgent call for environmental stewardship to preserve the river for future generations.
