Mike Reardon is a Principal Environmental Engineer based in California with more than 20 years of experience focused on due diligence, site assessments, and soil, soil vapor, and groundwater remediation for public and private sector clients, with work often completed at the direction of in-house or outside legal counsel.
As a consultant, Mike has performed or managed more than 50 Phase I environmental site assessments (ESAs), Phase II investigations, and vapor intrusion assessments. Many of these were performed at industrial properties and waste management facilities for clients such as Alcoa, Edwards Lifesciences, and Arizona Public Service. Mike also conducts assessments for large parcel re-development projects, such as those at the former U.S. Marine Corps Air Stations El Toro and Tustin in California. His public agency clients include the Orange County Transportation Authority, the Los Angeles Metropolitan Water District, and Orange County Waste and Recycling. Other key clients have included Chapman University, where Mike has assisted the University with real estate acquisitions and has lead remediation efforts of former industrial property for subsequent University use.
For due diligence projects, Mike frequently assists clients in identifying the current state of practice for conducting Phase I ESAs and the potential liabilities associated with incomplete data collection or unsupported conclusions regarding the potential for recognized environmental conditions. Mike also is the project manager for the firm's Hassayampa Superfund project in Maricopa County, Arizona, a hazardous waste disposal area west of Phoenix impacted by chlorinated solvents and a variety of other wastes. For the Hassayampa site, Mike led a dense non-aqueous phase liquid (DNAPL) source area investigation and developed the conceptual model identifying vapor phase transport as the predominant pathway for groundwater impacts. This prompted the design and construction of an innovative soil vapor extraction (SVE) system. Due to high concentrations of chlorinated solvents in the recovered vapor stream, the SVE system utilized an innovative and proprietary compression, chilling, and condensation technology for the cost-effective recovery of volatile organic compounds (VOCs) in a liquid form. More recently the SVE system has transitioned to carbon-based treatment due to significant declines in contaminant removal and the system is undergoing rebound testing and shutdown evaluations. Mike continues to manage on-going remediation, operations, maintenance, and monitoring activities at Hassayampa on behalf of a large group of industrial responsible parties.
