Abstract: is composed of a total of 116 drinking water contaminants.These 116 contaminants have already been detected in public water systems in the US and/or pose the risk of existing in public water supplies.Under the Safe Drinking Water Act (SDWA), the EPA is required to evaluate and determine whether to regulate at least five contaminants from the CCL every five years.Also, the EPA is required to issue a new list of no more than 30 unregulated contaminants to be monitored by public water systems (PWSs) every five years.The data in Unregulated Contaminant Monitoring Rule (UCMR) has been used in regulatory determinations as well.Currently, UCMR3 has been published and UCMR2 compounds may be regulated in the near future.The critical issue is that once those emerging contaminants are regulated, all of the drinking water systems will be required to monitor those contaminants regularly.In this review, the recent publications related to analytical method development, assessment, and removal of emerging contaminants in natural water resources and drinking water will be summarized to provide relatively comprehensive information to the researchers in this field.However, due to the large variety of lists of emerging contaminants, it is not possible for this review to cover all of them.This review mainly focuses on the following four groups of chemical contaminants: pharmaceuticals and personal care products (PPCPs); major disinfection byproducts, cyanotoxins, and pesticides and herbicides.The publications pertinent to specific water treatment technologies (such as free chlorine, monochloroamine, permanganate, ozone, UV, etc.), health risk assessments and ecological impact are not included in this review.In addition, literatures pertinent to emerging contaminants in air and other environments are also not covered in this review.
