The AT123D point of compliance, report presents trends in groundwater concentrations at a single point such as a groundwater monitoring well or property boundary. As with the other AT123D reports, this report contains a summary of the input parameters. The AT123D point of compliance, report presents trends in groundwater concentrations at a single point such as a groundwater monitoring well or property boundary. This report can be generated at any of the three-dimensional points modeled. As with the other AT123D reports, this report contains a summary of the input parameters. The SEVIEW help file provides a description of all SESOIL and AT123D input parameters.
Observation Well POCs
AT123D groundwater concentrations are now produced at Points of Compliance (POCs) also known as Observation Wells. Analytical models produced results at specific points (typically the top of the water table). In SEVIEW POC results are produced at specific depth and are then averaged for comparison with measured groundwater concentrations. The depth interval is typically based on existing groundwater monitoring well or piezometer specifications.
Toggle sources off/on without haveing to rerun either the SESOIL or AT123D models. Can be used to evalaute remedial options.
Simulation of multiple contaminant sources You can now simulate up to 15 separate contaminant releases in SEVIEW. Sources can be either a SESOIL vadose zone release or an AT123D groundwater plume.
Used to set the parameters of the POC. In addition to the x and y coordinates you can establish up to 10 points along the z-axis (depth) for each POC. SEVIEW averages the groundwater concentration over the depth interval for each POC.
Determine percent of contamination that comes from site vs off site sources.
Monthly groundwater concentrations. SEVIEW uses superposition to combine results from multiple sources that can be toggled on / off.
AT123D was enhanced to simulate multiple contaminant sources.
Graphs and data in the SEVIEW reports can be copied and pasted in to numerous programs including Microsoft Word and EXCEL.
