Understanding Water Pollution and Ecological Health in the Delaware Estuary

This guide explores the interconnectedness of land and water sources, highlighting how runoff pollutants impact the Delaware Estuary. Learn about point-source versus nonpoint-source pollution and its effects on local wildlife like oysters, horseshoe crabs, and shorebirds. Discover the food web dynamics from phytoplankton to commercial fisheries, and the critical roles of significant species. We also reflect on the historical context of waterway use, including the Schooner AJ Meerwald, to deepen understanding of our aquatic ecosystems and the importance of preserving them.
