Abstract There has been a growing interest in assessing the risks to the marine environment from produced water discharges. This study describes the development of a numerical approach, POM-RW, based on an integration of the Princeton Ocean Model (POM) and a Random Walk (RW) simulation of pollutant transport. Specifically, the POM is employed to simulate local ocean currents. It provides three-dimensional hydrodynamic input to a Random Walk model focused on the dispersion of toxic components within the produced water stream on a regional spatial scale. Model development and field validation of the predicted current field and pollutant concentrations were conducted in conjunction with a water quality and ecological monitoring program for an offshore facility located on the Grand Banks of Canada. Results indicate that the POM-RW approach is useful to address environmental risks associated with the produced water discharges.

The Department of Energy’s Environmental Management (EM) cleanup and closure mission involves unique management, regulatory, technical and administrative challenges, which differ from typical operating situations or other environmental cleanups. As the country’s first large nuclear cleanup and closure site, Rocky Flats Environmental Technology Site (RFETS) managers were faced with first-of-a-kind issues that required bold and innovative approaches to undertake and accelerate the closure effort. This was the case nearly two years ago when the project was challenged with the task of dismantling hundreds of gloveboxes from former nuclear production buildings.
