ROAM: Remedial Options Assessment Model

Remedial Options Assessment Model for soil and groundwater

ROAM is a user-friendly computer program that predicts transport of organic compounds from single or multiple sources in soil and groundwater. The program is designed to evaluate and compare the effectiveness of soil remediation alternatives such as capping, excavation, tank removal, and in-situ bioremediation; and groundwater remediation alternatives such as extraction/injection systems, slurry walls, gravity drains, in-situ bioremediation, and excavation. These alternatives may be simulated individually or in combination.

Questions ROAM Addresses:

What if we leave site as is?
How long before groundwater concentrations drop to acceptable levels by natural processes?
What if we cap the site?
How much waste or contaminated soil must be removed/remediated?
How much would in-situ decay have to be enhanced to meet water quality objectives?
How much can vapor extraction help?
How long must we pump and treat groundwater?

Uses of ROAM:

Quickly and cost-efficiently screen remedial options.
Determine whether more complex options are necessary.
Identify data needs based on sensitivity analyses.
Select appropriate well locations and minimize number of wells installed.
Evaluate likelihood that observed contamination is due to a given source.
Evaluate whether leaching from source is continuing.

RIVRISK is sponsored by the Electric Power Research Institute (EPRI), Palo Alto, California.
