Derek Tomlinson among Instructors for Courses on LNAPL Science, Technology

Derek Tomlinson, P.E., P.Eng., a Geosyntec senior engineer and hydrogeologist based in Pennsylvania, is among the instructors for a series of two-day courses upcoming in 2014 and 2015 entitled “Light Nonaqueous-Phase Liquids: Science, Management, and Technology.” The next session will be held October 29-30 at the Greater Richmond Convention Center in Richmond, Virginia, which is hosted by ITRC state member Virginia Department of Environmental Quality.

The course series is based on the Interstate Technology and Regulatory Council (ITRC) Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2), and is designed to assist environmental practitioners with applying science-based solutions to assess, remediate, and close LNAPL-contaminated sites. The ITRC guidance was developed through the combined efforts of environmental professionals, including state and federal regulators, consultants, and industry and community stakeholders.

Additional sessions for 2015 will be:

LNAPLs are organic liquids such as gasoline, diesel, and similar petroleum hydrocarbon products that cannot be blended with water and are less dense than water. Understanding LNAPLs is important because such liquids appear in the subsurface at thousands of remediation sites across North America and often are the sole reason why a site remains open. The spectrum of sites where LNAPL assessment and remediation efforts may take place include petroleum manufacturing and handling facilities, bulk product terminals, gas stations, airports, and military bases.
