ASW has supported the USACE and EPA Region VII effort at Omaha Lead since 2004, remediating over 1,500 properties.
As a prime contractor to EPA, Region VII, ASW's crews removed lead-contaminated soil from 425 residential properties at an average rate of 23 properties per week. ASW also provided all management, labor, and transportation, in addition to supervising subcontractors.
On-site health and safety supervision and training was provided by ASW, as well as property access, preliminary sampling of properties, and QA/QC.
As a subcontractor through the Preplaced Remedial Action Contract (PRAC), ASW performed the pre-removal, removal, and the post-removal activities.
ASW was awarded the EPA National Administrator's Award for Outstanding HUBZone Contractor for year 2006 for successfully performing and completing on schedule with ASW earning all possible incentives related to the hiring and training of local workers and the use of local firms as subcontractors.
Argonne National Laboratory
Over the course of more than a decade, ASW conducted environmental remediation for the Argonne National Laboratory, a division of the U.S. Department of Energy.
The massive project involved RI/FS, remedial design and action, monitoring and maintenance, and pilot studies at 35 former USDA grain storage sites.
Our duties as the prime contractor included project management, schedule and budget control, and all field work. We handled records research, property access agreements, regulator and stakeholdercommunications, long-term monitoring and maintenance, engineering and design support, and collection and preparation of sampling reports.
ASW completed the project under budget and ahead of schedule.
An especially interesting aspect of the project involved conducting environmental assessments using QuickSite® Expedited Site Characterization, which integrates sampling, analysis, data management, modeling and data interpretation to provide a comprehensive, performance-based approach to remedial alternatives.ASW is the only licensed provider of this method in the private sector.
ASW worked with regulators like the Nebraska Department of Environmental Quality, Kansas Department Health and Environment, Nebraska Department of Natural Resources andEPA Region VIIthroughout the project.
ASW received an Outstanding Performance rating that contributed to our winning the Small Business Administration Region 7 contractor of the year award.
Experimental Remediation Water Treatment Investigation
In Utica, NE, a small community west of Lincoln, ASW removed carbon tetrachloride from a community well using an experimental remediation system.
By volatizing the carbon tetrachloride using spray emitters – devices added to irrigation pumps – ASW managed to decontaminate the water for reuse in agricultural irrigation and wetlands development. The project also involved removing contaminants from the well in Utica utilizing the town’s own sewer system, saving the community thousands of dollars that it might have spent constructing a pipeline to transport and remove the contaminants.
ASW supported the Argonne National Laboratory during multi-phase RI/FS and remedial design. We helped geologically evaluate, design and install a 6-inch extraction well. We conducted the well pump test, collected geophysical data using downhole data loggers and took quarterly groundwater monitoring samples using cone penetrometer technology.
We managed the design of an experimental spray apparatus, consisting of a manifold system connecting to the extraction well, a pump house, 1,800 feet of piping, a mini weather system and a lined, one-acre retention pond to collect runoff.
In preparation for the remediation system, ASW provided construction, O&M and technical support for an evaluation of the remediation system. We also handled decommissioning, S&H and QA/QC.
We prepared the project’s submittals, managed data, conducted field sampling and data analysis and managed the subcontractor. ASW coordinated with the USDA, NDEQ, Village of Utica and local landowners to gain site and right-of-way access.
ASW completed all of this work under budget and ahead of schedule.
For our part in the project’s success, the client nominated us for the Small Business Administration Region 7 Contractor of the Year award.
Former Nebraska Ordnance Plant
ASW handled construction and geologic oversight of extraction, observation and monitor wells at the former Nebraska Ordnance Plant near Mead. We also constructed collection lines and a water treatment plant for removal of volatile organic and explosive compounds from groundwater. ASW used a Geoprobe® – a low-cost method for determining water levels and obtaining samples – to sample groundwater in preparation for well installation. Geoprobe® sampling has been effective in delineatingcontaminant groundwater plumes at the site.
Our other duties included: geologic borelogging and diagrams by a licensed geologist; and borehole geologic and environmental soil and water sampling.
