Overview

Spatial modeling study demonstrates improved groundwater vulnerability mapping using analytical network process weighting, suggesting effective targeting for pollution prevention.

Key Points

To assess and map groundwater vulnerability zones using modified DRASTIC approaches integrated with multi-criteria decision-making techniques in a geographic information system environment.
Modified the standard DRASTIC model by adding land use/land cover parameters within a GIS framework.
Calculated parameter weights using Analytical Hierarchy Process (AHP) and Analytical Network Process (ANP), followed by sensitivity analysis to identify dominant parameters.
Validated vulnerability zones across DRASTIC, Modified DRASTIC, Modified DRASTIC-AHP, and Modified DRASTIC-ANP models against field measurements of nitrate concentrations.
Modified DRASTIC-ANP showed the highest correlation with observed field nitrate concentrations compared to standard DRASTIC, Modified DRASTIC, and AHP-weighted versions.
Identified critical high-vulnerability zones where groundwater requires targeted remediation and protective measures against future contamination.
