Organic micrpopollutants, or emerging organic pollutants is an ill-defined group of organic contaminants that are abundant in the effluents of domestic wastewater treatment plants, but their toxicology and abundance information are still insufficient to establish enforceable maximal contaminant levels in drinking water. Common micropollutant groups include pharmaceutical and personal care products, fire retardants, plasticizers, complexation agents, steroidal hormones, antibiotic resistance genes, explosives and numerous other groups of compounds.The abundance of these compounds in wastewater plants in Israel, the fate of these compounds in a special wastewater treatment system that is widely used in Israel, namely, water recharge by Soil Aquifer Treatment, SAT will be addressed. ?The stability of some of these compounds in the SAT and how they can be used for quantitative evaluation of wastewater leakage to nearby drinking water wells will be demonstrated. The use of these compounds to model 3-D water recharge systems will be evaluated with a discussion of the consequences of a possible shut down and remediation of the recharge facility. Israel relies heavily on water reuse for irrigation, and I shall compare the contamination of wastewater leakage from the urban wastewater collection network to the impact of effluent reuse by irrigation.
Ovadia Lev is a professor of chemistry at the Institute of Chemistry. His research focuses on development of advanced materials for environmental and green chemistry and the analytical chemistry of trace organic contaminants. Professor Lev has been instrumental in providing science-based regulations, such as the Guidance manual for ozone disinfection in the USA, tools for quantification of leakage from Soil Aquifer Treatment systems to nearby drinking water wells, and quantification of wastewater leakage to water sources by quantification of emerging organic contaminants (micropollutants). Prof. Lev has contributed to the development of the fields of sol-gel electrochemistry and hydrogen peroxide sol-gel chemistry (including fundamental aspects and applications for lithium and sodium ion batteries), scanning electrochemical mass spectrometry (SCM) and scanning electrochemical microscopy (SECM). Prof. Lev is recipient of the Fulbright postdoctoral fellowship, the Key Innovations Award awarded by the Hebrew University, he is Fellow of the International Society of Electrochemistry, and recipient of the Rita Levi-Montalcini Award for scientific collaboration between Israel and Italy. The group is participating in a collaborative project in Singapore, holds a laboratory in the CREATE campus in Singapore and some of its members are stationed in Singapore.
