Brownfield Remediation

AST brings over 20 years of experience in remediating dilapidated and unused brownfield properties. These unique and challenging projects marry the two distinct operational units within our company, In-Situ Remediation and Environmental Construction. Examples of brownfield redevelopment sites that AST has remediated include gas stations, dry cleaners, and industrial properties. Contaminants of concern that have been addressed include but are not limited to,  petroleum hydrocarbonsPetroleum hydrocarbons are a group of organic compounds that are derived from crude oil or petroleum. These compounds are comprised..., chlorinated solventsChlorinated solvents are a group of organic compounds that contain chlorine and are commonly used in various industrial processes, such..., PCBs, and metals.

We support brownfield projects cradle to grave by first filling data gaps with high-density soil and groundwater sampling coupled with 3-D data visualizations using our unique qHRSC process that quantitatively defines the extent of contamination. We then develop a remediation strategy from a more comprehensive and quantitative conceptual site modelAbbreviated as CSM. The conceptual site model (CSM) is the communication tool that presents the understanding of the fate and... (CSM). Once the remediation strategy is developed, AST can implement a myriad of tasks that include but are not limited to:

• decontamination, demolition
• excavation and disposal
• soil mixing
• vapor mitigation
• amendment injection
