Annual Long-term Monitoring Status Report for the Los Alamos County Airport Landfill Cover System Replacement
CLIENT: Newport Nuclear News BWXT – Los Alamos (N3B)
BGI has been tasked to prepare the annual reports for 2019-2020 and 2020-2021. The Year 4 annual inspection report has been submitted and the Year 5 report is being prepared. The BGI Team is utilizing data and quarterly inspection reports provided by N3B. Inspections included water balance and methane monitoring, surface water control features, erosion controls, and site access control. The cover systems are currently in good condition and working as designed. There was some minor rill erosion noted at the base of the eastern side slope of the landfill at the end of Year 4. Measures taken including the installation of multiple rows of wattles have worked to mitigate further rill and gully erosion in the area.
