Geographic Information Systems (GIS)
A geographic information system (GIS) is the combination of computer hardware, software, and data that is used to capture, manage, analyze, and display all forms of geographically related information. Much more than a simple “map-making” program, a GIS can fully integrate geographical data with almost limitless other attributes (for example, environmental, population, or topographical data) to create powerful analysis tools for a wide variety of client needs.
AVESI specialists have a proven track record of developing and implementing GIS technology that serves as an efficient management tool throughout the life cycle of client projects. For example, AVESI scientists utilize GIS to manage, analyze, and display soil radioactivity data generated during investigations of potentially radioactive sites. GIS software is used to create color-coded maps of radiation levels across the site. The color-coded maps allow AVESI scientists and other decision-makers to visualize, analyze and interpret areas of elevated radioactivity in order to focus subsequent efforts on the specific zones needing additional investigation. Three-dimensional soil contamination modeling can be used to aid scientists and engineers in determining soil area and volume that require excavation.
Although the applications of GIS technology are nearly limitless, examples include:
- Analysis and mapping of environmental soil, groundwater, surface water, and air data
- 3-D modeling of environmental soil, groundwater, surface water, and air data
- Development of remedial soil volume estimates
- Demographic analyses for siting studies and market analysis
- Mapping and analysis of area topography for watershed studies
Three-dimensional representation of area topography:
- Mapping and analysis of area vegetation for forestry studies
- Mapping, analysis, and display of social data (for example, crime data)
- Analysis and display of agricultural data to improve crop yields
- Managing and displaying locations of utility locations such as subsurface electric, gas, and water lines
- Analysis and interpretation of satellite aerial photography
- Emergency management applications (e.g., street address mapping and route planning)
Three-dimensional contamination model
The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) under NUREG1575 provides detailed guidance for planning, implementing, and evaluating environmental and facility radiological surveys conducted in compliance with a dose- or risk-based regulation. The MARSSIM guidance focuses on the demonstration of compliance during the final status survey following scoping, characterization, and any necessary remedial actions.
AVESI’s team of radiological experts has implemented all phases of MARSSIM taking sites from Historical Site Assessments through Final Status Surveys to ensure the most productive use of client resources. Our MARSSIM professionals understand the nuances inherent in MARSSIM systematic planning and on-site analytical tools for real-time decision making to obtain a rapid, cost-effective, and compliant release.
AVESI has experience with various procurement contracts including:
- As a formal distributor for Fisher Scientific, AVESI supplied chemicals as well as laboratory supplies and equipment at discounted rates. AVESI supplied chemicals for the Formerly Utilized Sites Remedial Action Program (FUSRAP) lab in St. Louis, Missouri through the prime contractor to the United States Army Corps of Engineers.
- AVESI completed the procurement of laboratory appliances for the National Aeronautics Space Administration (NASA) in Cape Canaveral, Florida.
- AVESI completed a procurement contract with the Department of Veterans Affairs at Fort Detrick AFB. The contract required AVESI to manufacture and deliver 13 custom FIDLER (Field Instrument for the Detection of Low Energy Radiation) probes to Brooks AFB in Texas.
- To date, AVESI has been awarded numerous procurement contracts with the Department of Veterans Affairs at Jefferson Barracks in St. Louis Missouri supporting the VA Medical Center Employee Education Services Departments in Northport, NY; Little Rock, AR; and St. Louis MO.
- AVESI was a distributor for Office Depot supplying clients like the State of Illinois agencies with various office products and office equipment.
