In a October 2000 letter to the Port of Seattle, Water Resources Consulting LLC — writing on behalf of the Airport Communities Coalition — raised concerns about the SeaTac Aircraft Hydrant Fueling System project, arguing that construction should be delayed until an ongoing groundwater contamination study under the Model Toxics Control Act was completed. The letter criticized the project's environmental review (Declaration of Nonsignificance) for lacking specific details about leak detection, operating pressures, and contaminated soil management. The consultant warned that deep utility trenching could create preferential flow paths for existing fuel contaminant plumes, potentially threatening the groundwater supplies relied upon by nearby communities.
