Computer Modeling/Visualization

ATS International, Inc. are experts in the application of advanced computer modeling of physical systems. These services include computer simulations and visualizations to protect water resources, evaluate the fate and transport of existing contamination, optimizing the effectiveness of remediation strategies, evaluate and quantify risks associated with contamination, and provide court graphics and expert testimony in environmentally related cases.

Water Resource Protection

Computer modeling is the best available tool for predicting the behavior of subsurface contaminants. ATS International provides a variety of computer modeling services for water resource protection including:

• Wellhead Protection Analysis
• Watershed Modeling and Non-Point Source Modeling
• Surface Water-Groundwater Interaction Modeling
• Dissolved Phase Transport
• Seawater Intrusion Analysis

Remedial Strategies

Conventional engineering design of remediation systems has depended considerably on educated guesswork regarding system design, appropriate remedial endpoints, and time required to reach those endpoints. Consequently, remediation systems are often "over designed" at unnecessary cost to the client. ATS International utilizes computer modeling technology to reduce remediation costs by maximizing the effectiveness of the design and reducing overkill. Remediation systems that can be optimized through computer modeling include:

• NAPL Flow and Recovery
• Vacuum Enhanced Recovery
• Soil Vapor Extraction
• Multiphase Modeling of Soil Vaccuum, NAPL Flow, and Groundwater Recovery
• Containment Barriers

Risk Assessment

ATS International performs risk assessment modeling utilizing ASTM protocols to quantify risk to receptors. Properly conducted risk assessment can aid in remediation design by way of risk-based corrective action. Risk-based corrective action often means lower remediation costs and shorter times to acceptable endpoints.

Inorganic and DNAPL Modeling

ATS personnel have extensive experience in the evaluation and modeling of inorganic contaminants such as metals and pesticides. In addition, we are experts in the behavior and remediation of dense chlorinated solvents. These services include:

• Inorganic Speciation
• Inorganic Sorption/Leaching Modeling
• Dissolved Transport of Inorganic Containments
• Dissolution and Transport of DNAPLs
• DNAPL Flow and Recovery

Visualization and Animation

Using a suite of sophisticated software, ATS International can provide powerful visualizations and animations of topography, subsurface geology, plume migration, remediation, and more. These tools are a powerful means of increasing the understanding of experts and lay persons alike, and are particularly effective at enhancing expert testimony.
