The Wetlands at Long’s Park, completed in 2023, is an innovative water treatment system that is intended to improve the health, habitat value, and appearance of Long’s Pond. The system will also help improve the water quality in the Little Conestoga Creek, which flows into the Lower Susquehanna River, and will improve the health of the Chesapeake Bay. The project features a man-made natural treatment system or “treatment train” that includes a forebay with floating wetland islands, an iron-enhanced media filter, and two wetland marshes, which ultimately discharge to Long’s Pond.
