INTERIM MEASURES FINAL REPORT FOR SOIL-VAPOR EXTRACTION OF VOLATILE ORGANIC COMPOUNDS FROM MATERIAL DISPOSAL AREA L, TECHNICAL AREA 54
U.S. DOE, Office of Environmental Management, EM2018-0008, 124 pp, 2018
In 2015, a soil-vapor extraction (SVE) system operated at two vapor extraction wells in Material Disposal Area (MDA) L, Technical Area 54 of Los Alamos National Laboratory. Within 10 months, the two SVE units removed 1,217 lbs of total organic vapor mass, primarily from within a ~150-ft radius surrounding the extraction wells. Following the initial 10-mo SVE operation, short-duration rebound testing was performed in 2016 (2 days) and 2017 (25 days). Pore-gas sampling results collected within the 150-ft radius of the SVE units confirmed SVE operation had reduced the concentrations at most sampling ports to below their baseline values. Data collected during the interim measure was used to calibrate and validate a 3D model of the site, explore scenarios of hypothetical future releases, and present suggestions to support the selection and design of a final remedy for MDA L. https://www.energy.gov/sites/prod/files/2019/01/f58/EMID-700039-01_MDA_L_SVE_IM_Rpt_080618.pdf
