Historical Landfills in Alberta with Environmental Risk Rankings

Alberta's historical landfill locations, digitized from three sources. The data originates from a 1982 survey by MacLaren Plansearch Lavalin, which ranked sites by potential environmental and human health risk. Subsequent evaluations by Associated Engineering in 1985 and digitization by Alberta Environment and Protected Areas contributed to this spatial dataset.

Use Cases

• Mapping historical waste disposal sites based on their geospatial coordinates
• Assessing environmental risk for land development based on the MacLaren risk rankings
• Studying changes in landfill footprints over time based on digitized aerial photographs

Strengths

• Integrates data from three distinct historical sources: a 1982 survey, a 1985 evaluation, and a later digitization project
• Includes risk categorization for environmental and human health impacts

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic/temporal bias inherent to the original 1982 survey
