State and Federal Guidance Spotlight - Use of TS-CHEM for Estimation of NJDEP Classification Exception AreasThere are a number of state and federal regulatory documents that prescribe the use of solute transport models to support site investigation and remediation activities, along with guidelines on the types of analyses that need to be performed, models that should be utilized, and in some instances, specific input parameters that must be incorporated into analyses. In this first post in the “State and Federal Guidance Spotlight” series, we take a look at the New Jersey Department of Environmental Protection’s (NJDEP’s) Classification Exception Area Guidance, and how TS-CHEM can be used to estimate plume extent and duration to support the delineation of Classification Exception Areas for sites where impacts to groundwater may be present.

TS-CHEM Example Application - Receptor Impact AssessmentTS-CHEM is not only simple and easy to use, but it can be applied to a number of different common situations when it comes to impacted groundwater, making it the perfect tool for environmental professionals who perform groundwater investigation and remediation activities. In this blog post, we introduce the first Example Application in the series, which demonstrates how TS-CHEM can be used to model the length of a contaminant plume (in this case a benzene plume) in order to determine if it will impact domestic wells at a nearby residential development.

1-D vs 3-D Transport Analysis of Contaminant Plume ExtentContaminant 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 - ATRANSThe 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 ModelingEnvironmental 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 FeatureOne 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.
Learn more about the TS-CHEM map overlay feature HERE.
