PROGRAM PARTNERS<br />

PUBLICATIONS<br />

• Provided groundwater-modeling assistance to the <strong>Army</strong>’s independent<br />

technical reviews (ITR) and Groundwater Extraction and Treatment<br />

Effectiveness Reviews (GWETER) programs.<br />

• Provided telephone support and on-site technical assistance, as<br />

necessary, to installations conducting groundwater remediation<br />

activities. Site assistance was typically limited to less than one manweek<br />

of labor (per site) and travel costs.<br />

• Demonstrated the capability and cost-effectiveness of natural<br />

attenuation modeling in reducing remediation costs. This was<br />

accomplished by reducing the number of years required for active<br />

remediation systems such as pump-and-treat.<br />

• Distributed results from the demonstration projects to installation<br />

personnel to ensure technology transfer within the <strong>Army</strong>.<br />

• Provided groundwater-modeling services to Milan <strong>Army</strong> Ammunition<br />

Plant (AAP), Tennessee; Longhorn AAP, Texas; Pueblo Chemical<br />

Depot (CD), Colorado; the former Sacramento <strong>Army</strong> Depot,<br />

California; Umatilla CD, Oregon; Stratford <strong>Army</strong> Engine Plant,<br />

Connecticut; and Aberdeen Proving Ground, Maryland.<br />

Due to resource limitations, users can only receive support for less than<br />

one person-week without providing their own additional resources.<br />

USAEC’s institutional support is necessary for the continued success of<br />

the program.<br />

OPTIMIZATION OF IN-SITU VOLATILIZATION DEVICES<br />

Many <strong>Army</strong> installations use soil vapor extraction (SVE) to remove<br />

volatile compounds from soil, mainly because they can leave the soil in<br />

place during the cleanup operation and save money. This project is<br />

developing a model that installations can use to improve the design and<br />

operations of such in-situ remediation systems.
