1-D vs 3-D Transport Analysis of Contaminant Plume Extent

Contaminant plume analyses based on 1-D models are likely to overestimate plume extent. This may result in an overly-conservative assessment of impacts that are not likely to occur. More accurate evaluations of plume extent can be calculated using 3-D contaminant transport models. TS-CHEM provides a library of over 30 analytical 3D plume transport solutions for making these types of evaluations.

TS-CHEM Solution Library - ATRANS

The TS-CHEM program includes a comprehensive library of more than 30 different analytical solutions, each with different capabilities, including how they represent contaminant sources. For this first post in the Solution Library series, we will be focusing on the ATRANS family of models developed by Chris Neville at SS Papadopulos & Associates. In fact, the ATRANS1 model is included in the DEMO version of TS-CHEM!
Learn more about the ATRANS family of models, and how they can help evaluate groundwater plume transport scenarios HERE.

TS-CHEM - The Swiss-Army Knife of Solute Transport Modeling

Environmental professionals are often tasked with investigating contaminated sites to understand the nature and extent of contamination in groundwater, and select an appropriate remedy that will effectively limit migration of impacted groundwater, treat it, and prevent groundwater plumes from reaching sensitive receptors. To do this, a sound conceptual site model (CSM) is necessary, which requires not only collection of adequate site data (including groundwater sampling data, water level elevation data, and information on site hydrogeologic conditions) and application of professional judgement, but also the use of data analysis tools and techniques that allow for a better understanding of the fate and transport of contaminants in groundwater.
Learn more about how TS-CHEM can assist with developing a sound CSM HERE.

Visualize Your Modeled Plume with the New Map Overlay Feature

One of the most exciting recent additions to TS-CHEM is the new “Map Overlay” feature. After a concentration contour chart has been created and displayed, the TS-CHEM Map Overlay tool can be used to visualize the calculated plume. The plume is displayed as an overlay on a digital map, with the source located at the user-entered address. Attributes of the map and the plume can be modified using various Map Overlay controls.
