    How Investments in Clean Water Can Restore Ecosystems

    In March, after a long year of social distancing and cold, cloudy weather, two dolphins were spotted swimming up the East River in New York City. This atypical pair provided a much-needed sign of hope and recovery for City dwellers. Even more surprisingly, tiny seahorses can now be found clinging to oyster cages and other submerged objects in the lower Hudson River. These little seahorses, known as the Lined Seahorse, are one of many aquatic species that now make up a diverse and thriving ecosystem in the Hudson River estuary. For decades, the Hudson River was severely polluted after PCBs, oil, heavy metals and solvents were all dumped into the river by factories producing cars and paper. At one point, local fishermen could tell what color General Motors was painting cars based on the color of the river that day! In 1972, Congress passed the Clean Water Act to restrict “point sources” such as factories and power plants from discharging contamination into US waterways. Over the nearly 50 years that have passed since then, NYC has invested more than $12 Billion to upgrade wastewater treatment to improve the health of the Hudson’s delicate, aquatic ecosystems. And, it has worked. A 2017 report by the NYC Department of Environmental Protection found that the Hudson River is the cleanest it has been in over a century as evidenced by the presence of the Lined Seahorse that would not be found in the Hudson River without these extraordinary cleanup efforts. Efforts such as these give us hope that if we take measures now our ecosystems can, indeed, be restored. We must also remember to stay vigilant in protecting our waters to ensure healthy ecosystems for future generations. Photo Credit: Tina Walsh for Hudson River Park
