Investigation &


Nova's Expertise

Nova’s technical staff includes Professional Geologists (PG) and Professional Engineers (PE) with extensive experience in performing real estate due diligence, site investigations, and corrective action/remediation. Nova’s staff has experience in the design and implementation of a wide range of investigative methods and mitigation/remediation technologies, including: natural attenuation, soil excavation, land spreading, thermal treatment, landfill disposal, groundwater pump and treatment, soil-vapor extraction, sub-slab depressurization, air sparging, and chemical and bio-remediation



Remedial Investigation and Corrective Design

Nova designs and implements Remedial Investigations (RI) and Corrective Action Design (CAD) programs for a wide variety of sites. An RI determines the nature, extent, and magnitude of a contamination. A CAD provides an action plan for any necessary remediation/cleanup. An RI/CAD also addresses the protection of public health and the environment.


Consistent with the RI/CAD process, Nova personnel develop a detailed feasibility study analysis to establish practical mitigation solutions that are feasible and can be cost-effectively implemented. The majority of Nova’s projects have been completed in response to mandates from regulatory agencies acting under authority of CERCLA, RCRA, and/or various other state and local programs.
