The Conceptual Site Model (CSM) is the core communication tool that defines how contaminant mass is distributed, moves, and transforms at a site. A precise CSM is essential for successful soil and groundwater remediation. At AST Environmental, every CSM is built from a combination of historical site investigations and high-resolution data collected through our Remedial Design Characterization (RDC) process.

Taking the CSM to the Next Level

AST integrates quantitative, high-resolution groundwater and soil sampling, advanced geophysical methods, and detailed aquifer characterization to produce a CSM with unmatched accuracy. This depth of understanding allows us to design surgical remediation plans that minimize both cost and project duration while maximizing treatment effectiveness.

Flexible Presentation Format

The CSM is tailored to the site’s complexity and project needs. Deliverables can range from concise tabular datasets and 2D maps to advanced 3D contaminant transport models. Upon request, AST develops interactive 3D visualizations that allow stakeholders to clearly see contaminant pathways and targeted treatment zones.

Proven Impact on Site Closure

AST’s history of meeting and exceeding cleanup goals is directly tied to the precision of our CSMs. By combining detailed data acquisition with targeted remediation design, we consistently deliver results that close sites faster, more efficiently, and with greater regulatory confidence.
