INVESTIGATION OF A SUSTAINABLE APPROACH TO IN-SITU REMEDIATION OF ARSENIC IMPACTED GROUNDWATER
U.S. EPA Region 2, EPA/600/R-19/102, 59 pp, 2019
A study conducted at the Vineland Superfund site (New Jersey) examined the optimization of an in situ As immobilization technology to replace or augment an existing pump and treat system. Key processes controlling As immobilization were determined through bench-scale testing, geochemical modeling, and groundwater/aquifer characterization. Field data showed that As and Fe concentrations were reduced from levels around 1,000-15,0000 µg/L to levels as low as 10 µg/L-1,0000 µg/L, respectively. Results from this work can be used to optimize the design and operation of the full-scale system and provide guidance for the design of air sparge systems at sites with similar conditions. https://cfpub.epa.gov/si/si_public_record_Report.cfm?dirEntryId=348256&Lab=CESER
