Digital Model Study of Groundwater Contamination by Diisopropylmethylphosphonate (DIMP), Rocky Mountain Arsenal Near Denver, Colorado
Abstract
The Rocky Mountain Arsenal requested that the USGS conduct a digital- model study of the DIMP contamination of ground water on the arsenal and surrounding property in order to provide data useful in meeting the requirements of the cease and desist order. Specific information was needed concerning the area affected, concentrations, and rate and direction of movement of the plume of contaminated ground water. In addition, an evaluation was made to determine whether or not Brighton's municipal well fields will be affected and, if so to determine future arrival times and concentrations. The study was undertaken in three phases. Phase I involved the conversion of the existing chloride transport model of the arsenal to a DIMP transport model in order to evaluate the magnitude of the ground water contamination in the immediate area of the arsenal. Phase II involved building a second DIMP transport model of a larger area in order to investigate the potential for DIMP moving into the city of Brighton's field well and other adjacent areas.
