Problems/Comments

This site is located in the northeastern part of Ground Water Zone 2 and was identified using historic aerial photographs depicting a trench and fill as well as a horizontal tank. Groundwater flow is suspected to flow to the north towards Eskimo Creek and two groundwater monitoring wells are located approximately 500 feet to the south associated with soil treatment cells. One sample returned a DRO concentration above the cleanup level with a concentration of 572 mg/kg. Surface water and sediment samples collected north of the site in Eskimo Creek had no sample results above the cleanup levels. Additional sampling will be requred to determine the nature and extent of the contamination in the vicinity of the sample that had a DRO concentration above the cleanup level.
