Richard Rago, Senior Associate at Haley & Aldrich, is the lead author of a new article in Groundwater Monitoring & Remediation. U.S. Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection provided input on the anonymous study’s design, which included the collection of 25 school building samples and 61 office building samples. The study identified some volatile organic compounds (VOCs) ubiquitously in indoor air background, and some at concentrations which exceeded risk-based regulatory screening levels.

Ryan Miller is the East Region Manager of the Land Science® division of REGENESIS, Inc., and is based on the East Coast. Ryan’s role includes providing technical support in the design and installation of Land Science vapor mitigation systems, and educating the environmental community on the advancements in vapor intrusion barrier technology, implementation, and quality control. Ryan has extensive experience in the environmental consulting industry, most recently working as a New Jersey Licensed Site Remediation Professional (LSRP) focusing on brownfield redevelopment projects and specializing in vapor intrusion mitigation.

A growing manufacturer looking to expand its operations purchased a vacant industrial facility in Lansing, Michigan, where chlorinated solvents were used and spilled into the subsurface. The environmental consultant was asked to address the suspected vapor intrusion concerns resulting from the former industrial operations. In working with the Michigan Department of Environment, Great Lakes & Energy (EGLE), the consultant proposed utilizing the Retro-Coat® Vapor Intrusion Coating System, in combination with passive venting, to ensure safe indoor air for the future workers.

Developed by the R&D Team at Land Science, the Retro-Coat system is the most appropriate coating technology for vapor intrusion protection. The Retro-Coat Vapor Intrusion Coating System is a complete product line that consists of chemically resistant materials to properly protect existing structures from the threat of contaminant vapor intrusion. A vapor intrusion condition is most commonly found when the existing structure was operating as, or in close proximity to, a dry cleaner, gas station, or manufacturing facility.

While several new players are emerging in the environmental remediation market over the past few years, companies such as REGENESIS have been providing leading-edge environmental remediation solutions since 1994. The company is a global leader in the research, development, and commercialization of technology-based solutions for the environment. It specializes in providing scientifically proven product and service-based solutions for groundwater and soil remediation at contaminated sites. Learn more by reading the featured article.

The former brownfield site was targeted for redevelopment in the nation’s capital. The project is a 32,000 square feet mixed-use development in the heart of Washington, D.C. The environmental consultant specified the MonoShield® vapor barrier system with passive venting as a proactive step to prevent vapor intrusion of low-level petroleum hydrocarbon vapors. The MonoShield vapor barrier system was included in the site’s Corrective Action Plan and was approved by the Department of Energy and Environment prior to its installation.

MonoShield is a chemically resistant and easy-to-apply barrier specifically designed as a preemptive solution for vapor intrusion at brownfield redevelopment sites. It is backed by unparalleled design support, robust warranty options, and a network of certified applicators who can ensure quality installation.
