| Title: | Analysis and remediation of an underground storage tank problem in the Albuquerque Basin, NM |
| Authors: | Gehweiler, Kathryn A. |

| Abstract: | Contamination of groundwater in Albuquerque's south valley poses a potential threat to the health of the city residents, to continued industrial growth in the area, and to the principal aquifer of the Rio Grande basin. The Rio Grande underground water basin is regulated as a sole source of potable water by the State of New Mexico.
The purpose of this study was to take the perspective of the consultant hired to investigate two sites suspected of contamination. The sites are located in Albuquerque's south valley. The consultant must determine, through a series of logical steps, whether contamination exists, where the contamination is most likely to be located, what the contaminants are, what the lateral and vertical extent of the contamination is, and how to remediate the problem.
The consultant used a stepwise approach, which involved a description of the study area, a site investigation, and a remedial investigation/feasibility study to evaluate the sites. Using this approach, monitoring wells were installed at the site and water samples were collected. Available analyses of the water samples verified the presence of contamination and determined the type and concentration of the contaminants (see table III, p.24). A soil gas survey and additional water sampling was recommended for defining where the contamination was most likely to be located and to determine the lateral and vertical extent of the contamination. A remediation scheme was proposed based on the data available, but was not refined or implemented pending further information.
It was concluded that information about local aquifer parameters needed to be ascertained before a detailed remediation plan could be developed. Preparation of a groundwater model would be useful for adjusting the remediation systems and in evaluating the impact of the remediation methods on the contaminant plume(s). |
