Chlorinated solvents such as tetrachloroethene (PCE) and trichlorethene (TCE) are among the most
commonly detected hazardous organic compounds encountered in groundwater. These compounds
are one of the most ubiquitous and recalcitrant pollutants of groundwater and soil. Compound-
specific isotope analysis (CSIA) is an innovative approach that can provide a unique insight into the
origin and fate of contaminants in the subsurface, including the examination of transformation
mechanisms and degradation pathways of these compounds in the field.
Over the last decade, carbon CSIA has been successfully utilized in assessing various contaminated
sites across the globe. Recent analytical advancements in chlorine and hydrogen CSIA have opened
new possibilities and enabled consultants and researchers to start employing chlorine and hydrogen
CSIA in their case studies. The application of dual element CSIA approach increases the resolution of
the CSIA method and improves the possibility to differentiate between natural and anthropogenic
organic compounds even if biodegradation occurs.
