A Cleaner Future for Mashapaug Pond

Mashapaug pond, which at times turns an artificial neon green, has been a no-go zone for years. Stormwater pollution flows here from roughly 70 industrial and commercial properties in the neighborhood. Every time it rains or snowpack melts, oil, grease, chemicals, and other sediment wash from nearby paved surfaces – around industrial facilities and a shopping center – into the pond.
