摘要

Background/Objectives. A 3D isotope approach was used based on compound-specific isotope analysis (CSIA) of carbon (C), chlorine (Cl), and hydrogen (D) to investigate a 60-acre dissolved-phase chlorinated ethene plume in central New Jersey, USA. The chlorinated volatile organic compounds (CVOCs) detected in groundwater at our client’s upgradient site, primarily trichloroethene (TCE) and its degradation products, mix with CVOCs from downgradient off-site sources to form a commingled groundwater plume in the overburden and bedrock. The objective of the CSIA investigation was to distinguish TCE from off-site sources, including TCE produced from the biological reductive dechlorination of perchloroethylene (PCE), from TCE released at the client’s site.
