Multimedia Contaminant Fate, Transport, and Exposure Model (MMSOILS)

The Multimedia Contaminant Fate, Transport, and Exposure Model (MMSOILS) estimates the human exposure and health risk associated with releases of contamination from hazardous waste sites. The methodology consists of a multimedia model that addresses the transport of a chemical in groundwater, surface water, soil erosion, the atmosphere, and accumulation in the food chain. The methodology is intended for use as a screening tool. It is critical that the results are interpreted in the appropriate framework. The intended use of the exposure assessment tool is for screening and relative comparison of different waste sites, remediation activities, and hazard evaluation. The methodology can be used to provide an estimate of health risks for a specific site. Since the uncertainty of the estimated risk may be quite large (depending on the site characteristics and available data), MMSOILS addresses these uncertainties via Monte Carlo analysis.

This tool will help achieve the goal of the following objectives

Less Contamination
Less Emissions
Less Traffic Noise
Connectivity and Inclusion
Healthy Destinations
Less Traffic Violence
Active Transportation
Green Space

Estimation Technique

MMSOILS is based on the premise that contaminants are transported through the environment by multiple media (air, water, soil). The model considers the physical and chemical properties of the contaminants, as well as the environmental conditions that affect transport. MMSOILS can be used to predict the concentration of contaminants in each medium at various locations, downwind or downstream from a source. The model can be used to estimate exposure to contaminants from multiple sources, including transportation activities. MMSOILS is a tool that can be used by environmental regulators and planners to assess the potential risks of contamination from transportation activities. The model can also be used by various industries to evaluate the potential impacts of their operations on the environment.
