Contamination Assessment and Site management Tool (CAST)

CAST provides an online application for the assessment of contaminated sites, specially for BTEX-type contaminations. The specific highlight is a web-based application for calculating steady-state plume length $L_{max}$ using MODFLOW and MT3D-MS.

The site can be assessed from www.cast.iitd.ac.in

Flask micro web-framework is used for the web-application development. The front end has been designed using HTML, CSS and bootstrap, the back-end is being handled by the open source management system, MySQL and Python(3.6.8). The application currently can already be used for:

1. Statistical Analysis of Contaminated sites:

   • Large contaminated site database
   • Statistical measures and visualizations of important site quantities

2. Analytical Models for steady-state plume length $(L_{max})$ estimations:

   • 2D Vertical Model (Liedl et al., 2005)
   • 2D Horizontal Model (Ham et al. 2005, Chu et al., 2005)
   • 3D Model (Liedl et al., 2011)
   • More to be added ...,

3. Empirical Models for $L_{max}$ estimations:

   • 2D Vertical (Maier and Grathwohl, 2005)
   • 2D Vertical with richarge (Birla et al. 2019 - in revision)
   • More to be added ...,

4. Numerical Models for plume length estimations:

   • Web-interface for MODFLOW/MT3DMS
   • Single reactant reactive transport model based on Yadav et al., 2013.
   • More in the development ...,

5. Decision model for selection of model for site-assessment

   • Based on Yadav et al., 2020 (in revision)
