Geosyntec was the design-build Contractor for two projects involving the remediation and disposal of low-level Naturally Occurring Radioactive Material (NORM) wastes at two sites in Malaysia. These sites are associated with a plant that extracted rare earth elements from local tin ores. Because of the naturally occurring radioactivity contained in the raw materials, these productions were accompanied with by-products and residues containing low-level thorium hydroxide and uranium hydroxide.

An industrial firm retained Geosyntec through its Malaysian subsidiary, GSM Consultancy, for professional services at an operating electronics manufacturing facility in Kuala Lumpur, Malaysia. The objectives of the work were to characterize the distribution of volatile organic compounds (VOCs) in the subsurface; assess the potential for subsurface vapor intrusion to indoor air; and provide data for the design of a sub-slab depressurization (SSD) system for mitigation optimized for minimal disruption to ongoing production activities at the facility.
