18 Feb History of Long Island Sound
Perhaps as many as 10,000-15,000 Indians live near Long Island Sound, harvesting bountiful fish and game along the shore and in interior forests.*
In 1614, Dutch explorer Adriaen Block completes his final expedition to the Sound. Block, the first European to sail the entire Sound, opens the Sound to trade. Colonial settlers clear forests for farms and settle in seaside communities for trade, fishing, and whaling. Indian tribal influence dwindles by late 1600s.
Commerce grows, and the Sound and its tributaries become known for brass and metal finishing, textiles, hatmaking, and oystering. The Sound is prized for its beauty and becomes a source of inspiration for American Impressionist painters. But the Industrial Revolution also brings intense growth and pollution.
Manufacturing declines, while postwar housing production leads to a population boom and suburban sprawl. The first comprehensive study of water quality shows evidence of human impact affecting oxygen levels.
Low levels of dissolved oxygen contribute to fish kills in the western Sound. Nationally, concerns about the health of America’s waterways lead to the 1972 federal Clean Water Act.
Congress creates the Long Island Sound Study (LISS). Field surveys identify low levels of oxygen, later related to nitrogen pollution, as the greatest environmental threat to the Sound.
LISS adopts the Comprehensive Conservation and Management Plan (CCMP) to restore and protect the Sound. The cleanup plan includes actions to address hypoxia, reduce toxic substances and pathogens, and restore natural habitats.
CT, NY, and the EPA adopt a plan to reduce human sources of nitrogen pollution to the Sound by 58.5 percent by 2014. Through the Habitat Restoration Initiative, the Study also adopts goals to restore 2,000 acres of habitat and 100 miles of river for fish passage by 2008.
EPA approves CT and NY’s “Total Maximum Daily Load” of nitrogen to the Sound, allocating responsibility to meet the 58.5 percent reduction goal.
LISS adopts the 2003 Long Island Sound Agreement, establishing measurable targets to implement the CCMP and to restore the health of the Sound by 2014, the 400th anniversary of Block’s final exploration.
LISS establishes the Sentinel Monitoring Work Group to examine the effect of climate change in different areas of the Sound and its coast. Researchers and resource managers will collect information to help the region understand potential climate change impacts and to learn how to adapt to climate change by adjusting the way Long Island Sound is managed.
