SiteCrest's Natural Attenuation Tool (NAT) uses the Domenico (1987) three-dimensional analytical solute transport model to compute the natural attenuation of chemicals in the saturated zone in combination with other dilution models to account for partitioning, leaching and groundwater mixing. These are the same models applied in the Canadian Council of Ministers of the Environment protocols for deriving soil (CCME, 2006) and groundwater (CCME, 2015) guidelines, the Canada-Wide Standard for Petroleum Hydrocarbons in Soil (CCME, 2008), the Alberta Environment and Protected Areas Tier 1 and Tier 2 groundwater guidelines (EPA, 2024a,b), and the United States Environmental Protection Agency BIOSCREEN Natural Attenuation Decision Support System (US EPA, 1996).
