Pharmaceutical emerging micropollutants potential in septic tanks: Its fate and transport study in Indonesia – A literature review

Micropollutants also known as “emerging micropollutants” (EMPs) have gained significant attention in research, with a particular emphasis on the ocean, marine water, and river pollution. The interest arises from the impact of EMPs on aquatic ecosystems, often originating from sources such as wastewater treatment plant (WWTP) and septic tanks leakage. However, EMPs pollution in surface water can also be caused by leakage of septic tanks. In Indonesia, where septic tanks maintenance is generally neglected, there is a potential risk of EMPs contamination. The outcome and transformation of EMPs, as well as their potential transport pathways, are influenced by sanitary conditions and the effectiveness of existing septic tanks. This concern has escalated to the point of causing fecal contamination in drinking water sources. Therefore, this research focuses on EMPs, specifically pharmaceutical EMPs, leakage from septic tanks, and their possible fate and transport. It also discusses related perspectives of previous research related to EMPs contamination due to leakage of septic tanks.
