Improved drinking water quality after adding advanced oxidation for organic micropollutant removal to pretreatment of river water undergoing dune infiltration near The Hague, Netherlands

AOP decreases the number and concentration of OMP and chances of negative impact on ecology and groundwater quality.AOP decreased OMP concentrations in drinking water with no measurable negative effect on water quality parameters.MARR produces water with a highly stable chemical and microbiological composition and levels out seasonal peak fluctuations.There is redundancy in OMP removal by MARR and AOP, but AOP is able to remove certain OMP that MARR is not, and vice versa.
