Anthropogenic emissions of long-lived halocarbons, namely chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs), methyl
chloroform (CH$_{3}$CCl$_{3}$), and carbon tetrachloride (CCl$_{4}$) represent the largest source of atmospheric chlorine. A
large fraction of the end uses of these compounds have resulted in the dumping of chlorine-containing equipment and
materials in waste sites from which leakage is now occurring. Previous work at two US landfills in Eastern Massachusetts has
shown that landfill gas emissions may be a significant source of atmospheric chlorine. This idea was further explored
during a field campaign in southwestern Britain in July/August 2004. Flask samples were taken at several landfills with
varying waste composition, landfill age, and basin geology. The flasks were analyzed for CFC-12, CFC-11, CFC-113,
CH$_{3}$CCl$_{3}$, and CCl$_{4}$ using GC-ECD. Results will be shown for the UK landfills as well as a comparison between
the US and UK sites.
