Geosyntec Staff Contribute Vapor Intrusion Expertise to Environmental Managers Magazine
Deran Pursoo (Arizona), Dave Folkes, and Ted Kuehster (Colorado) are contributing authors for an article entitled "Site-Redevelopment for Commercial Expansion Using Plastic-Dome Forms for Aerated Floor Construction" in the Air & Waste Management Association (A&WMA) Environmental Managers (EM) Magazine March 2018 issue.
The article discusses commercial expansion over former industrial parcels and landfills with contaminated soils via utilization of low-cost methane mitigation systems that use a sub-slab matrix of thermoplastic, structural domes, to provide sub-floor aeration and collection of soil gas beneath building floor slabs. Comparative results from plastic dome and gravel layer installations at a newly constructed 20,000 square foot building in Tempe, AZ are included with intent to promote the importance and value of effective, efficient, and "green" engineering control methods for soil gases.
