Records relate to research carried out by Viitala and colleagues at Lakehead University as part of the Acidic Precipitation In Ontario Study. Field research was done at Hawkeye Lake northwest of Thunder Bay, and at Pukaskwa National Park. The records include data, photographs, reports and research papers. Some records also relate specifically to the International Symposium on Acidic Precipitation held at Muskoka on September 15-20, 1985.

Records date primarily 1980-1988, with some additional documents from 2018 and 2022.

Consists of reports, letters, and minutes of the Lakehead Region Conservation Authority.

A media kit, produced by Grand Council Treaty Number 9. Titled "Reed's Greed," the materials here relate to opposition to Reed Paper (Canada) Ltd., the company responsible for mercury pollution in the English & Wabigoon River system, affecting the people of Grassy Narrows First Nation/Asubpeeschoseewagong Netum Anishinabek.

Most material dates from 1976. At this time, Reed was planning an expansion of its forest products operations and requesting increased timber rights from the Ontario government. This is also a time after the mercury pollution had been identified by researchers and made known to governments, but long before any settlements were reached.

Documents include media releases, clippings, information sheets, and posters for protest events in Winnipeg.

Most materials are in English; some in an Indigenous language written in syllabics.
