The Leopold matrix is a qualitative environmental impact assessment method developed in 1971 by Luna Leopold and collaborators for the USGS. [1] It is used to identify and assign numerical weightings to potential environmental impacts of proposed projects on the environment. [1]
Risk assessors rely on both laboratory (e.g., toxicological) and epidemiological data to make these determinations. [7] Illustration of a site conceptual model for environmental exposure. Conceptual model of exposure. Hazards have the potential to cause adverse effects only if they come into contact with populations that may be harmed.
In the United States, an environmental site assessment is a report prepared for a real estate holding that identifies potential or existing environmental contamination liabilities. The analysis, often called an ESA , typically addresses both the underlying land as well as physical improvements to the property.
