Mary Minor founded Citizens Urge Protection of the Environment (C.U.R.E.) in 1983 as a result of area residents discovering four Superfund landfill sites within Adams County, Pennsylvania. C.U.R.E. became a grassroots leadership organization with a mission to bring all people closer to the reality of a cleaner environment and precious natural resources. This collection contains correspondence, reports, meeting summaries, newspaper clippings, notes and hearings with State and Federal legislators and environmental agencies relating chiefly to Keystone Landfill.

This collection documents the activities, primarily, of the Pennsylvania Environmental Network (PEN), a now defunct environmental advocacy organization active in southeast Pennsylvania in the late 1990s to early 2000s. Materials capture the efforts of the Pennsylvania Environmental Network, the committees Tina Daly served on, and other advocacy efforts of organizations with the network, which helped bring together dozens of local and regional environmental advocacy groups. The main research value of the collection can be found in about half a linear foot of PEN newsletters.

This collection documents the environmental activism of the Alliance for a Clean Environment (ACE), a grassroots environmental advocacy group formed in Pottstown, Pennsylvania in 1995. The records chronicle the history of specific environmental health concerns in the southeastern Pennsylvania region, such as exposure to toxins through radiation and landfills. The records are focused on four topics: administrative information about the organization; information on the fight against the Pottstown Landfill; information on the fight against the Occidental Chemical plant; information on the fight against Limerick Nuclear Power Plant. Included are organization correspondence, dossiers on campaigning politicians, studies they requisitioned from independent scientists, permit and violation information, reports from the different sites, strategic plans, and promotional materials. Researchers may be particularly interested in the nearly 80 VHS cassettes and DVDs of The ACE Report. The Ace Report was broadcast via the local public access channel from 2000 to 2012. It provided scientific information, expert opinions, and legislative updates to Pottstown residents.
