Adaptive Long-Term Monitoring at Environmental Restoration Sites

The objective of this ESTCP project was to demonstrate and validate the use of the Sampling Optimizer (SO) and Data Tracker (DT) software (the Summit Software), offered by Summit, at three Department of Defense (DoD) sites. The three demonstration sites were as follows: Former George Air Force Base (GAFB) Site, Victorville, CA Former Nebraska Ordnance Plant (NOP) Site, Mead, NE Camp Allen Landfill Site, Norfolk, VA Monitoring and Remediation Optimization Software (MAROS) (developed by GSI Environmental, Inc.) was also applied at one of the three demonstration sites. The Summit Software demonstrated in this ESTCP project provides a set of tools for long-term monitoring optimization (LTMO) and consists of two major modules: SO identifies redundant sampling locations (spatial optimization), or redundant locations and frequencies (spatiotemporal optimization), in historical data. DT allows current monitoring data to be reviewed against selected historical data (i.e., the background data) to identify cases where current data deviate from expectations that are based on the background values and patterns.
