Investigation of the northwest area of Rocky Mountain Arsenal
The goal of the Rocky Mountain Arsenal (RMA) northwest area effort was to evaluate groundwater pollution of the near surface aquifer in this area of the Arsenal. To accomplish this goal, sufficient additional geological, hydrological, and water chemistry data was collected to interpret existing information and provide data from parts of the study area where little or no data previously existed. Soil samples were collected to provide geological and hydrological information. Well water samples were drawn to determine groundwater chemistry. The most significant water constituents were DIMP, DCPD, DBCP (Nemagon), and fluoride. Similar geological and hydrological results were obtained as previously mentioned. Fluoride levels exceeding the acceptable standard appeared to be crossing the northwest Arsenal boundary. High DIMP concentrations were observed in an area generally northwest of the northwest part of Basin F. The existence of DCPD could not be established because of problems with sampling. DBCP was observed at very low concentrations at widely dispersed on-post sites. These results must be reviewed later as on-going work is completed in neighboring areas which impact upon the area of RMA. In particular, possible contamination of a deep aquifer may require investigation.
