Case study
Groundwater Vulnerability Mapping with DRASTIC
Risk zones mapped from 7 hydrogeological parameters
The problem
Groundwater contamination risk is spatially uneven and requires multiple hydrogeological factors to be considered together.
Our approach
We implemented the DRASTIC model using 7 hydrogeological parameters to produce contamination risk zones for Tirunelveli.
- Assemble the 7 hydrogeological parameter layers.
- Standardize and combine the layers through DRASTIC.
- Generate contamination risk zones.
- Lead a 3-member implementation team.

Results
- Contamination risk zones mapped from 7 hydrogeological parameters.
