Impact/Purpose:
The presence of arsenic in water and soil is a global concern since it is identified as a carcinogen and presents a serious threat to human health. This study was conducted at the Vineland Superfund Site (New Jersey, USA) and examined the optimization of an in-situ arsenic immobilization technology to replace or augment an existing pump and treat system to treat contaminated groundwater. The work is of interest to the international environmental community, including EPA’s regional, program, and local partners.
Description:
The Vineland Chemical Company operated from 1949 to 1994 producing arsenical herbicides and fungicides. A Record of Decision (ROD) signed in 1989 addressed remedial actions at the site which included a pump and treat (P&T) system to remediate arsenic in groundwater. A Remediation System Evaluation (RSE) optimization study conducted in 2010, ten years after the onset of the P&T system, found that the current P&T system was unlikely to restore the aquifer within a reasonable time period as specified by the ROD. Because the annual cost for the P&T system is very high, the study listed several recommendations designed to optimize or replace the P&T system, including in-situ remediation for arsenic immobilization.
