“…For monitoring bores, standing water level was first measured using a Solinst interface probe, and then continuously monitored during low-flow pumping, along with field physio-chemical parameters (electrical conductivity, oxidation-reduction potential, dissolved oxygen, temperature, and pH). These parameters were monitored using a multi-parameter field probe (YSI Pro Plus or HACH HQ40D) [15]. Samples were collected following stabilization of these parameters.…”

Aquifers provide integral freshwater resources and host ecosystems of largely uncharacterized, truncated endemic microorganisms. In recent history, many aquifers have become increasingly contaminated from various anthropogenic sources. To better understand the impacts of nitrogen contamination on native groundwater ecosystems, 16S rRNA sequencing of the groundwater microbial communities was carried out. Samples were taken from an aquifer known to be contaminated with nitrogen from multiple sources, including fertilizers and wastewater treatment plant effluents. In total, two primary contaminants were identified: NH4+ (<0.1–3.7–26 mg L−1 NH4+ min-median-max), and NO3− (<0.01–18–150 mg L−1 NO3− min-median-max). These contaminants were found to be associated with a decrease/increase in microbial species richness within affected groundwater for NH4+/NO3−, respectively. Important phyla were identified, including Proteobacteria, which had the highest abundance within samples unaffected by NH4+ (36–81% NH4+ unaffected, 4–33% NH4+ affected), and Planctomycetes (0.05–10% NH4+ unaffected, 43–72% NH4+ affected), which had the highest abundance within the NH4+ affected samples, likely due to its ability to perform anaerobic ammonia oxidation (ANAMMOX). Planctomycetes were identified as a potential indicator for the presence of NH4+ contamination. The analysis and characterization of sequencing data alongside physicochemical data showed potential to increase the depth of our understanding of contaminant behavior and fate within a contaminated aquifer using this type of data and analysis.

“…For δ 18 O of nitrate, atmospheric deposition and NO 3 − fertilizer are +17 to +25‰ and +25 to +75‰, respectively, while the δ 18 O-NO 3 − values sourced from microbial nitrification of NF, SN and MS are appreciably lower than those of AD and NO 3 − fertilizer, and often vary from −5‰ to +15‰ (Kendall and McDonnell, 1998;Mayer et al, 2001). Nowadays, several studies reported successful application of the dual stable isotopes of NO 3 − to characterize the sources and processes affecting NO 3 − in water bodies such as Adebowale et al (2019) and Hu et al (2019b). Furthermore, to develop quantitative information on NO 3 − source apportionment in water bodies, Xue et al (2012) introduced a powerful tool known as the Markov Chain Monte Carlo mixing model that was adopted from isotopic analysis of food-webs.…”

Many studies have focused on the concentrations of pollutants in influent and effluent of wastewater treatment plants [6][7][8]. However, their impact on surface water and groundwater has rarely been reported.…”

Municipal wastewater reclamation and reuse has been an effective way to solve problems of shrinkage and drying up of rivers and lakes. The residual pollutants in recycled water may pose a risk to groundwater. A field study on the spatial and temporal variations concentrations of nitrate, ammonia and chemical oxygen demand (COD) was conducted in Beijing, where recycled water is used to recharge dry rivers. And the effect of a riverbank filtration (RBF) on the nitrogen and organics removal from the Qingyang River was investigated. Water samples from recycled water, river water and groundwater were collected for nitrate, ammonia and COD measurement. The results indicated that river water quality was improved when recycled water was refilled to the river course. The concentration of nitrogen and total phosphorus decreased along the flow directions in the Qingyang River. Higher temperature in summer can promote nitrogen and COD removal in the river. The results indicate that about 63%, 89% and 41% of nitrate, ammonia and COD was removed from the river bank filtration. These results indicate that improving the removal of nitrogen and organics in recycled water and optimizing the management of recharging operation could reduce the risks of nitrogen and organics.
