About the Lab
Professor Sung-Tak Yoon's research lab specializes in environmental geochemistry and hydrogeology, focusing on the fate and sources of contaminants in groundwater and urban sediments. The lab investigates nitrate pollution in alluvial aquifers, particularly in relation to agricultural and domestic water use, and examines heavy metal distribution in urban roadside environments. Using isotopic and multivariate statistical techniques, the lab identifies pollution sources and assesses environmental risks in urban and agricultural settings. Their work supports the development of science-based environmental policies and pollution mitigation strategies in Korea and similar regions.

15Abstract To investigate the origin and behaviour of nitrate in alluvial aquifers adjacent to Nakdong River, Korea, we chose two representative sites (Wolha and Yongdang) having similar land‐use characteristics but different geology. A total of 96 shallow groundwater samples were collected from irrigation and domestic wells tapping alluvial aquifers. About 63% of the samples analysed had nitrate concentrations that exceeded the Korean drinking water limit (44·3 mg l −1 NO 3 − ), and about 35% of
