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 in 2014 entitled "Light Nonaqueous-Phase Liquids (LNAPL): Science, Management, and Technology. The first session is April 1-2 at the InterContinental Kansas City at the Plaza in Missouri.
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.
The hosts for the April course session are the Nebraska Department of Environmental Quality and the Kansas Department of Health and Environment. The second session will be held June 3-4 at the Hyatt Regency Lexington in Lexington, Kentucky, to be hosted by the Kentucky Department for Environmental Protection, Division of Waste Management, in partnership with Kentucky Petroleum Marketers Association. Pre-registration is required to attend.
A third session is set for October 29-30 in Richmond, Virginia, to be hosted by the Virginia Department of Environmental Quality. Registration opens May 1.
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.
In 2012, Mr.Tomlinson earned the ITRC's Industry Recognition Award for his contributions to the council's Dense Non-aqueous Phase Liquids (DNAPL) Site Characterization team. Geosyntec is well represented on the team, which also includes Principal Mary deFlaun, Ph.D. (Princeton); Associate Gary Wealthall, Ph.D. (Guelph); and Associate Bruce Marvin (Oakland).
