NV5 - Closed Lincoln Landfill

Closed Lincoln Landfill

NV5 prepared a conceptual site model (CSM) to assess the sources and extent of a contaminant plume emanating from the landfill property. Using the results of the CMS, we then designed a perimeter cutoff trench dewatering system to prevent contamination of groundwater at the site. The cutoff trench will lower the groundwater level to below the bottom of the waste and extract the existing plume to meet the requirements of the California Water Quality Control Board.

NV5 provided construction quality assurance observation and materials testing services during construction and operation and maintenance (O&M) activities, including system startup monitoring and reporting. We also are providing ongoing monthly O&M, telemetry monitoring, sampling and analysis, and reporting.

NV5’s innovative design for this project saved the City of Lincoln approximately $12 million.
