From 1926 until 1986, the Remington Arms Company operated a trap and skeet shooting range at Lordship Point (also known as Stratford Point) in Stratford, Connecticut. Located along the Long Island Sound near the mouth of the Housatonic River, shooters fired lead shot at clay pigeons (brightly colored clay targets in the shape of inverted saucers) launched over upland ranges and the open waters of the Sound. Over the course of 60 years, an estimated 48 million clay pigeons and three million pounds of lead shot were deposited throughout the property, shoreline and tidal waters off Lordship Point.

In 1985, the Connecticut Department of Environmental Protection (CT DEP) conducted an investigation to examine the lead contamination at Lordship Point and issued an order requiring Remington to cease the discharge of lead shot by December 31, 1986. A subsequent study in 1987 found high lead levels in blue mussels and acute lead poisoning in American black ducks wintering along Lordship Point. Overall, 12 acres of shallow water tidal habitats and 29 acres of fringe salt marsh and uplands were contaminated with lead. To remediate the site, approximately 71,000 cubic yards of contaminated sediment and soil was removed and processed at an on-site dewatering and processing plant. Lead shot was separated from the sediment and transported to a nearby facility for recycling. Clay fragments containing polycyclic aromatic hydrocarbons (PAHs) were also separated and disposed of in a solid waste landfill. The remedial activities were completed in 2001 and the plant was demobilized and removed from the site. A fringe salt marsh that was excavated during the cleanup was also restored.

In a 2004 settlement with the potentially responsible parties (PRPs), the U.S. Fish and Wildlife Service (USFWS), National Oceanic and Atmospheric Administration (NOAA) and the State of Connecticut received $218,000 in compensation for injuries to natural resources. The funds were combined with settlement funds from the Raymark Industries Superfund Site and Connecticut Trustee SubCouncil of the Housatonic River RCRA Site to restore 34 acres of tidal salt marsh at the Great Meadows Marsh Unit (GMMU) of the Stewart McKinney National Wildlife Refuge. Additionally, the PRPs were required to secure a Conservation Restriction (CR) on the Lordship Point property and plant 8.2 acres of native coastal grasses to restore an upland grassland.
