In this paper, an environmental multimedia modeling system (EMMS) that combines a risk assessment with a Monte Carlo method (MCM) was used to explore the interaction between groundwater and surface water with respect to chemical exposure and risk. The EMMS‐MCM simulations incorporated several key influencing factors that are inherent in traditional predictions of subsurface and surface‐water interactions, including soil permeability coefficients and parameters such as hydraulic conductivity, density, recharge, layers, and depth. These influencing factors are generally associated with the largest sources of uncertainty in modeling and pose significant challenges to water management and to the optimal allocation of water resources. A case study involving benzene at the Trail Road landfill site located in the Ottawa–Carlton area of Canada is presented to illustrate the use of the EMMS‐MCM approach. The model results are verified by comparisons to the results of groundwater and surface‐water investigations in the landfill. The EMMS‐MCM results are evaluated using a risk quotient (RQ) risk assessment method to quantify environmental risk. The EMMS‐MCM simulations can be used to support hazardous field work and contribute to environmental management by predicting the possible consequences of hazardous chemical contaminations in surface waters and groundwater. The integration of the EMMS‐MCM and RQ approaches represents an appropriate tool for the accurate assessment of long‐term pollutant risks and environmental management of surface‐ and groundwater resources.
