SoBRA's NAPL subgroup is working on facilitating and clarifying dissemination of NAPL assessment guidance and as part of this work, SoBRA is preparing a LNAPL mobility tool. One of its functions is to predict the potential of various LNAPL to migrate in different aquifers. They are seeking data on typical wetting angles for LNAPL respective to different lithologies. If anyone is able to provide site specific values that have been measured, please contact Anna Hitchmough Further information about the subgroup is available here.
