A method is proposed to evaluate changes in health risks from ground water drawn from specified locations in the subsurface as a result of the transport of contaminant chemicals from buried waste sites.
To evaluate the health risk, a stochastic one-dimensional contaminant transport model is solved with Monte Carlo simulation.
The risk at a specified location is equal to the number of times that contaminant concentrations exceed the health standard concentration divided by the number of iterations in the Monte Carlo simulation.
The method is used on a simulated aquifer to demonstrate how health risks vary with time and location in the subsurface.
