Charles-George Reclamation Trust Landfill, Superfund landfill site in Tyngsborough, Massachusetts

The Charles-George Reclamation Trust Landfill is a 19-acre (7.7 ha) hazardous waste site in Tyngsborough, Massachusetts, one mile (1.6 km) from the town center near the Dunstable border. It lies between Dunstable Brook to the west and Flint Pond Marsh and Flint Pond to the east. A 2.6 MW solar farm with 10,000 panels now covers the capped landfill.

The site began as a small municipal dump in the 1950s and expanded to accept industrial and chemical waste materials over time. Operations ceased in 1983, after which the property entered a long phase of remediation and environmental oversight.

The name comes from Dorothy and Charles George, the site's former owners, who in 2003 settled all claims against them for $3.8 million. The trustees later paid the Massachusetts Division of Fish and Wildlife $1.2 million in 2004 and $625,000 in 2007 to establish conservation land in Tyngsborough and neighbouring Dunstable.

The site is not open to casual public visits because active management and monitoring remain in effect. For information, contact the EPA or local authorities, which publish regular updates on safety conditions and environmental status.

The formerly contaminated property now hosts a 2.6-megawatt solar farm that has fed electricity into the local grid since 2017. The transformation demonstrates how old industrial sites can become sources of renewable energy production.
