Tacoma Goodwill Yakima Branch

The site property was historically used as an auto dealer, repair, and/or body shop from 1942 to 1964 according to Polk city directories and Sanborn fire insurance maps. 
 
A 600-gallon steel underground storage tank (UST) was discovered when a test pit was dug during remediation activities relating to the Yakima Railroad Area groundwater monitoring project. About 250 gallons of liquid and sludge were removed from the tank. The product was determined to be heavy oil, which indicated the tank was either used for heating or waste oil. Soil staining was noticeable around the fill pipe, but there were no signs of pitting or rusting on the tank. Once the tank was removed from the pit, dark grey stained soil was discovered.

The stained area in the pit was over-excavated so that the north, south, and west ends extended to a depth of 8 feet below ground surface. Soil samples were collected from each of these walls and analyzed for total petroleum hydrocarbons. The excavation resulted in 35 cubic yards of stockpiled soil. Three representative samples collected from the stockpile found TPH at 24-2620 parts per million. The soil was approved to be transported and treated at Anderson Landfill.
 
Based on the sampling results, groundwater should not have been impacted by soil contamination.

Based upon cleanup activities and a Site Hazard Assessment conducted in August 2011, Ecology has determined the site is no longer a threat to human health and the environment.  Ecology issued a no further action determination in August 2011.
