IVI leverages 20 years of technical knowledge and regulatory experience with assessing hazardous wastes and toxic materials - then selecting, designing, and implementing the most appropriate remediation strategy. As their advocate, our environmental specialists have helped clients save millions of dollars in erroneously assigned liability.
Site remediation means many things to many people - removing pollutants from soil or groundwater, addressing leaking underground or aboveground storage tanks, cleaning up active industrial facilities, or restoring abandoned (Brownfield) sites for redevelopment. Each situation presents a unique scenario of technical and regulatory issues that must be balanced in the most cost-effective and practical manner.
We offer a full arsenal of investigative tools and analytical techniques for modeling the transport of contaminants in soils, groundwater, surface water, sediments and air, and, where appropriate, use risk-based assessment techniques to evaluate the impact of such contaminants.
To mitigate organic and inorganic chemicals in the subsurface, our geologists, hydrologists, chemists, and environmental engineers go beyond traditional "dig and haul" strategies, if warranted. By employing innovative in-situ approaches - such as barrier technologies, chemical oxidation, bio remediation, and phytoremediation - we can help you reduce costs, site and operational disturbances, and shorten the clean-up schedule. IVI has extensive hands-on experience with Fenton's Reagents, a chemical oxidation method, successfully cleaning-up numerous sites.
Our regulatory specialists - well versed in programs such as CERCLA (Superfund), RCRA and state-level rules - help ensure your site's compliance with applicable standards and assist in negotiated voluntary cleanups. And, as your advocate, IVI's environmental forensics experts will endeavor to find the most cost effective systems that comply with your holding strategy.
