A November 2000 letter from the Washington State Department of Ecology to Seattle-Tacoma International Airport summarizes the completion status of environmental tasks required under Agreed Order 97TC-N122. The order mandated a comprehensive groundwater study of the Airport Operations and Maintenance Area (AOMA), including hydrogeological research, contamination mapping, and development of groundwater flow and contaminant transport models.

A November 2000 memo from Washington State Department of Ecology's Roger Nye raises concerns that the Port of Seattle failed to adequately identify potential soil and groundwater contamination sites at Sea-Tac Airport, as required by an Agreed Order.

The memo calls for a thorough, honest effort to identify all potential contamination areas that could pose risks to nearby drinking water wells and surface waters.
