The report summarizes the presentation and follow-up discussions from the Puget Sound Microlayer Workshop that was held in Seattle on 15 and 16 November 1989. A group of nine experts, together with representatives from EPA and Puget Sound Water Quality Authority was assembled to make presentations and participate in panel discussions on selected topics related to microlayer contamination. The primary goals of the workshop were to transmit technical information among the workshop participates and audience and to clearly identify what is known and not known about microlayer processes related to contamination, biological exposure, and effects. The primary emphasis of the workshop was on an assessment of the currently available information on Puget Sound. However, information from other geographic areas was used as appropriate or where Puget Sound data were not available. A second workshop goal was to identify data gaps and microlayer research needs required to develop effective pollution prevention and control strategies in Puget Sound. The results of the workshop were intended to be used by the sponsoring agencies to assess the magnitude and severity of microlayer problems and to determine the extent to which studies of microlayer contamination justify agency funding and support relative to other environmental problems in Puget Sound.
