Site Assessment and Screening Plan - Seattle, WA
A $90 million dollar commercial building is being built on a former Dairygold site in Seattle,
WA.  The site had historically had underground storage tanks for the fueling of vehicles,
additionally; the site is located in an old industrial area of the Seattle area.  

Phase II ESA activities detected petroleum hydrocarbons and metals that were above MTCA
method A limits and halogenated hydrocarbons, benzene, and petroleum hydrocarbons were
also found to be present in the ground water above EPA drinking water standards and MTCA
Method A limits for ground water.

SNR conducted an assessment and helped develop a soil screening process to allow most
of the excavated soils to be sent as fill material at other sites, saving the property owner over
$3 million in disposal costs.
