Quantifying gas phase chlorine compounds in sewer system headspaces

The presence of chlorine-bearing compounds in sewer headspaces is a potential risk to personnel and can cause decay of valuable infrastructure through increased rates of corrosion. There is however little information available on their speciation and concentration in these systems as standard methods for sampling them from sewer headspaces do not exist. In addition, the system factors influencing their presence have not been studied. The project will assemble methods for sampling and analyzing chlorine-bearing compounds in sewer headspaces. The techniques will then be employed to characterize concentrations in York Region sewers and pump stations.
