Environmental Remediation
From the construction of simple remediation systems to large complex multi‑task remediation projects, HSA's engineers and construction managers have the capability to design, construct, manage, and maintain remediation projects of all sizes. Our ability to provide innovative solutions, manage risk, and execute projects within budget is what sets us apart from the competition. From the development of strategies through the implementation, operation and maintenance of full‑scale remediation construction projects, HSA works proactively on behalf of our clients to minimize costs, risks, and provide the highest quality product.
To support our broad range of remedial technologies and innovative remedial solutions, HSA’s construction personnel are well trained and experienced in remediation activities. Our portfolio of successful projects includes: remedial investigation/feasibility studies (RI/FS) associated with Superfund sites; numerous RCRA Facility Investigations (RFI)/Corrective Measures Studies (CMS); State coordinated Contamination Assessment and Remedial Action Plans (CAP/RAP) associated with hundreds of state projects in connection with petroleum, drycleaning solvents, heavy metals, pesticides and explosives; and numerous Brownfields projects. We provide safe handling and disposal of soil, sludge and groundwater, effectively managing your project's environmental responsibilities.
