Operational information and monitoring data collected over the full year of 2017 are presented for interim measures (IMs) installed to address mainly hydrocarbons (benzene, naphthalene) at the former Coke Oven (CO) special study area located at the Tradepoint Atlantic property, Baltimore County, Maryland. The IMs currently in operation at the CO are located within five distinct smaller areas designated as Cells 1-3, 5, and 6. Cell 1 has an air sparge/soil vapor extraction (AS/SVE) system; Cell 2 has an AS/SVE system in the shallow groundwater zone and groundwater pump and treat system in the intermediate zone; Cell 3 has an AS/SVE system; Cell 5 has a dual-phase extraction system for the shallow zone and a coal tar DNAPL recovery system; and Cell 6 has multi-phase extraction of LNAPL. This progress report provides a brief description of each IM system; notable operations activities that occurred during 2017; a discussion of operational and analytical data from 2017; an evaluation of the effectiveness of the IM systems; and recommendations for continuation or modification of the current IM systems. https://mde.maryland.gov/programs/LAND/MarylandBrownfieldVCP/Documents/Sparrows%20Point%20Hazardous%20Waste%20Site/Coke%20Oven%20IM%20Progress%20Report%20rev.0%202-9-2018.pdf
