Kalakaket Creek RRS - Landfill 1
Diesel, Petroleum Product
Past Work on Site
Subsurface soil detection of DRO below ingestion and inhalation cleanup levels. DRO did impact groundwater at the site. One well detected DRO at 4.5 mg/L in groundwater. Remote location of site and accessibility of other water sources makes groundwater at this site an unlikely future drinking water source. The 2010 Decision Document and Record of Decision stated that the selected remedy for contaminated soil at this site includes ICs to limit access, exposure, and use of petroleum contaminated soils. A report documenting the condition of the landfill and Performance report on ICs is due every 5 years until DEC approves discontinuation. The ICs have been documents in USAF's Real Property Records, Kalakaket RRS General Plan, and 611th IRP Records. For groundwater, monitoring wells will be sampled for GRO, DRO, RRO, VOCs, and PAHs annually. After 5 years DEC may decrease the frequency. A report that compares the current data to historical data must also be submitted. --Updated August 2011-- Site is currently in long term monitoring status. The Work Plan for Long Term Monitoring at this site was approved on 8/18/2011. The first round of long term monitoring samples are expected to be taken during the summer of 2011.
