Detecting Emerging Contaminants in Groundwater: Risks to Ecosystems and Human Health

Abstract

Groundwater ecosystems, which provide a critical source of drinking water and support diverse ecological functions, are increasingly threatened by emerging contaminants such as pharmaceuticals, personal care products, and industrial chemicals. These pollutants, including antibiotics, flame retardants, and microplastics, often enter groundwater through various pathways such as leaching from landfills, seepage from septic systems, and agricultural runoff. Once in the environment, their persistence and ability to spread pose significant risks to both ecosystems and human communities. This study reviews the infiltration mechanisms, persistence, and dispersion of these contaminants, highlighting the challenges of detection due to their low concentrations and complex chemical compositions. The ecological and human health risks associated with these pollutants are substantial, necessitating urgent action. The findings emphasize the need for advanced detection technologies, stricter monitoring protocols, and enhanced regulatory frameworks to mitigate the risks posed by these emerging contaminants, particularly in regions where groundwater serves as a vital resource.
