In 2006, Mundell was retained to provide consulting services at a Ball State University steam generation facility that had been the subject of environmental investigative activities since 1993 when it was discovered that that fuel oil had been released from an on-site underground storage tank. After historical review and site investigations, Mundell determined that: (1) groundwater impacts were limited in effect and distribution; (2) the vapor exposure pathway was incomplete, and; (3) SPH materials were effectively immobilized within a geologic formation beneath the site. Mundell then proposed a risk-based approach to achieve site closure without further monitoring or remediation, including the placement of an Environmental Restrictive Covenant (ERC) on the property that defined a specific zone of soil impacts, restricted uncontrolled groundwater use, and limited future usage of the property to non-residential purposes……Read More »

Variation in Hydraulic Conductivity and Retardation Factor and its Effect on Numerical and Analytical Model Results
Soil and groundwater contaminated with Perchloroethene (PCE) was discovered at the a dry cleaner site in Columbus, Indiana during a Phase I Investigation. In an effort to bring the remedial efforts to an effective closure, Mundell was retained by a partnering consulting firm to evaluate the stability of the dissolved organic plume using groundwater flow and chemical transport modeling……Read More »
Comprehensive Operation and Maintenance Program
In an effort to reduce groundwater treatment system costs, Mundell decided to turn over the operation and maintenance (O&M) of one of its remediation systems to a sub-contractor located much closer to the system than Mundell. Mundell developed and then trained the sub-contractor using the step by step written guidelines for all routine maintenance procedures, site visit procedures, and sampling procedures. These procedures allow Mundell to retain responsible oversight of the system O&M with minimal time invested……Read More »
GIS Analysis Indicates Chemical Risks Present for Urban Communities
Mundell acted as grant project manager and coordinated all technical task activities, communication and submittals to the U.S. EPA for a scientific study to determine if air quality was more likely impaired near low income and minority populations. A GIS based approached was used for this environmental justice grant to the United States Environmental Protection Agency Region V on behalf of the Indianapolis Urban League Environmental Coalition. The results of the relational data evaluation indicated that low-income citizens and people of color are disproportionately located near Toxic Release Inventory facilities in Marion County. As a result, there is a greater potential for impact to these populations’ health from these facilities than the average Marion County population and certain areas were targeted for increased future monitoring……Read More »
Investigation – Rapid Delineation of MTBE Plume
Mundell initiated an expedited site investigation at a petroleum facility location near an elementary school to delineate the extent of an MTBE plume and implement remedial measures. By completing over 131 direct-push soil borings and sampling 45 monitoring wells across a wide area, Mundell was able to limit the number of groundwater monitoring wells to the precise number necessary for long-term monitoring and to complete the investigation in approximately half the normal time……Read More »
