Article Synopsis
- Groundwater quality in South Asia, particularly India, is heavily impacted by various pollutants, with limited studies on how anthropogenic pollutants, like polycyclic aromatic hydrocarbons (PAHs), affect it.
- A study found that lower and medium molecular weight PAHs, such as naphthalene and phenanthrene, were present in significant percentages of aquifer sediment samples in the Ganges river basin, but their levels in groundwater were much lower than in river water.
- Experiments revealed that certain PAHs adsorbed differently depending on sediment composition, and numerical modeling indicated that irrigation practices could significantly accelerate the movement of these pollutants in aquifers by up to 25 times.
