abstract = {Aerobic Granular Biomass (AGB) technology is widely used for urban and industrial wastewater treatment,
however, its application in groundwater remediation, is practically unknown. A mixture of carbendazim,
simazine, and diuron were amended to the nitrate-polluted synthetic groundwater at increasing concentrations
to validate the ability of technology to remove both kind of pollutants, pesticides and nitrate which are
commonly found in the water resources. The nitrate removal was a success with values below 0.010 g⋅L-1. The
increased concentration of pesticides in the influent did not distort the pattern observed for pesticide removal.
Carbendazim was almost completely eliminated, followed by simazine elimination, while diuron showed
adsorption-desorption patterns during experimentation. The addition of pesticides had a drastic effect on the
basal community conducted by proliferation of Hyphomicrobium and Dokdonella. The pesticide compounds had a
negative effect on number of copies for fungal population, while archaeal population was unharmed, according
to qPCR results. Denitrifying bacteria need 70 days as acclimatization period for achieving activity values as
initial inoculum. The results obtained have shown for the first time the capacity of AGB system to treat
groundwater polluted with nitrate and pesticide using low carbon load. Therefore, the results suggested the
potential application of AGB technology for the purification of groundwater polluted with both nitrates and
pesticides},
