- W233217967 abstract "Surveys of groundwater quality in the Pearl River Delta alluvial aquifer were carried out by sampling 20 shallow wells to determine the level of contamination from nitrate in Zhuhai City. The samples have four chemical types in the study area; however, the chemical composition of the groundwater in the dry season does not show marked differences from that of the wet season. Nitrate concentrations from as low as 0.05 mg NO 3 - /L to a maximum of 151 mg NO 3 - /L were observed in the groundwater during April 2006. The recommended maximum allowable concentration for nitrate in drinking water according to the WHO of 50 mg NO 3 - /L nitrate was exceeded in 27.5% of the samples collected in two seasons. There were five groundwater samples with nitrate concentrations changing dramatically in the rainy season. According to the distribution of δ 15 N, no sample was within the δ 15 N range for synthetic fertilizer, while 12 out of 13 samples had δ 15 N values (> +10‰) of compost-derived nitrate, i.e. animal/sewage waste." @default.
