We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


In August 2014, during activities related to a shoreline erosion mitigation project, petroleum-contaminated soil was discovered at the Barrow Sewage Pump Station 4, located on property owned by Arctic Slope Regional Corporation. Diesel range organics were confirmed in subsurface soil above the DEC Method 1 cleanup level. Other petroleum compounds were confirmed below DEC cleanup levels. Contamination is believed to be due to past activities. The site and surrounding area were used for diesel and gasoline fuel storage for the village power plant and village store from the 1940s to 1960s. There is anecdotal information that a storm in October 1963 may have resulted in damage to fuel drums stored on site and the subsequent release of a large volume of fuel. Review by DEC of the investigation on the property will allow DRO contaminated soil to remain on the property at levels that are above the maximum allowable DRO concentrations (maximum of 13,000 mg/kg); however, the area where greatest concentrations were detected will be encased within sheet pile walls being constructed to prevent flood and erosion.
