That's the question The Journal News/LoHud.com will answer Sunday and Monday in a two-part series analyzing the water quality and other environmental issues affecting The Hudson River and Long Island Sound.
The two essential waterways, so much a part of life for residents of Rockland, Westchester and Putnam counties, have seen significant improvements in recent decades. But much work remains to clear them of the toxic reminders of our industrial past and byproducts of our present-day life.
Sunday, we take a look at Long Island Sound, the vital estuary of the Atlantic Ocean, along with the Westchester shoreline. On Monday, we explore the historic Hudson River and the banks of the Lower Hudson Valley.Interactive graphics
