Dam Failures

Rebuilding failed dams may occasionally make sense, but in most cases allowing rivers and streams to revert to their natural state will help make the region and its coastal ecosystem more healthy, resilient and sustainable.

Long Island is facing a water crisis, with regard to both the fresh drinking water aquifers that sustain our daily lives and the salty coastal waters that enrich them. This crisis is reflected by what has been a steady, many decades-long deterioration in water quality, from excess nitrogen fueled by human sewage, to toxic plumes and spills, all while we “mine” our water supply by taking out more water than is being replenished.
