11/25/2020: The Port of Anacortes is currently evaluating alternative hydrogen sulfide (H2S) monitoring systems. The monitors may occasionally be offline between shipments. We are required to monitor H2S during prilled sulfur shipments. We will support the current system through at least summer of 2021. Below are the data from a new H2S monitoring system we trialed during the last sulfur shipment (11/6/2020 to 11/14/2020). If you have any questions about the Port of Anacortes’ Environmental Programs or Ambient Monitoring, please contact Kevin Anderson (firstname.lastname@example.org or 360-299-1827).
