Article Synopsis
- Groundwater in Kabul, sourced from both shallow and deep aquifers, is facing quality deterioration due to unlicensed wells caused by rapid urbanization and population growth.
- A multi-parameter study of hydrochemical and environmental isotopes revealed that water-rock interactions significantly influence groundwater chemistry, with distinct chemical characteristics discerned between shallow and deep aquifers.
- The research underscores the hydraulic connections between aquifers, indicating that the shallow aquifer recharges the deep aquifer, and provides crucial insights for the sustainable management of Kabul's water resources.
Identification and apportionment of groundwater nitrate sources in Chakari Plain (Afghanistan).
Environ Geochem Health
November 2023
The Chakari alluvial aquifer is the primary source of water for human, animal, and irrigation applications. In this study, the geochemistry of major ions and stable isotope ratios (δH-HO, δO-HO, δN-NŌ, and δO-NŌ) of groundwater and river water samples from the Chakari Plain were analyzed to better understand characteristics of nitrate. Herein, we employed nitrate isotopic ratios and BSIMM modeling to quantify the proportional contributions of major sources of nitrate pollution in the Chakari Plain.

This study targets the DRASTIC, evidential belief function (EBF), and logistic regression (LR) models to assess vulnerability in Kabul aquifers, Afghanistan Country. The growth of urban sprawl, groundwater overexploitation, and lack of suitable municipal sewage systems as anthropogenic sources have been the main potential to increase groundwater contaminants such as nitrate in the study area.
