Article Synopsis
- - The study investigates how agricultural practices influence groundwater quality, particularly focusing on sulfur compounds in areas with different farming systems in South Korea over a year-long period.
- - Groundwater chemistry showed significant variations due to factors like groundwater pumping, fertilizer use, and denitrification, leading to elevated levels of manganese, iron, and sulfate, while nitrate levels were low.
- - Periodic groundwater pumping and agricultural fertilizers were found to alter the oxidation processes affecting sulfur in the water, raising concerns about high sulfate concentrations that could pose health risks in drinking water.
Riparian zones with their buffering ability and abundant water supply are often subjected to intensive agricultural activities. We investigated a riparian aquifer located near a stream in South Korea that recently experienced sharply decreasing groundwater levels and elevated nitrate (NO) concentrations, which were attributed to local agricultural activities. Our goal was to identify the predominant nitrogen sources and NO removal processes.
