“…Other possible biogeochemical reactions such as biodegradation of disinfection byproducts and sulfate reduction were also investigated. Reduction in the disinfection byproduct N-nitrosodimethylamine in the recycled water from 2.5 to 1.3 ng L À1 in the postbreakthrough groundwater was observed (Patterson et al, 2012). The most dominant OTU of Betaproteobacteria sequences showed close resemblance to sequences of genus Achromobacter of order Burkholderiales, and these organisms were identified from polycyclic aromatic hydrocarbons-contaminated soils (La Rosa et al, 2006).…”

Managed aquifer recharge offers the opportunity to manage groundwater resources by storing water in aquifers when in surplus and thus increase the amount of groundwater available for abstraction during high demand. The Water Corporation of Western Australia (WA) is undertaking a Groundwater Replenishment Trial to evaluate the effects of recharging aerobic recycled water (secondary treated wastewater subjected to ultrafiltration, reverse osmosis, and ultraviolet disinfection) into the anaerobic Leederville aquifer in Perth, WA. Using culture-independent methods, this study showed the presence of Actinobacteria, Alphaproteobacteria, Bacilli, Betaproteobacteria, Cytophaga, Flavobacteria, Gammaproteobacteria, and Sphingobacteria, and a decrease in microbial diversity with an increase in depth of aquifer. Assessment of physico-chemical and microbiological properties of groundwater before and after recharge revealed that recharging the aquifer with aerobic recycled water resulted in elevated redox potentials in the aquifer and increased bacterial numbers, but reduced microbial diversity. The increase in bacterial numbers and reduced microbial diversity in groundwater could be a reflection of an increased denitrifier and sulfur-oxidizing populations in the aquifer, as a result of the increased availability of nitrate, oxygen, and residual organic matter. This is consistent with the geochemical data that showed pyrite oxidation and denitrification within the aquifer after recycled water recharge commenced.

“…However, a threshold BDOC concentration may not be required for biotransformation if the organic carbon is sourced from sediment organic carbon. Recently, Patterson et al (2012) reported the degradation of NDMA in water treated by reverseosmosis that was recharged into an anaerobic aquifer. Fig.…”

This study developed relationships between the attenuation of emerging trace organic chemicals (TOrC) during managed aquifer recharge (MAR) as a function of retention time, system characteristics, and operating conditions using controlled laboratory-scale soil column experiments simulating MAR. The results revealed that MAR performance in terms of TOrC attenuation is primarily determined by key environmental parameters (i.e., redox, primary substrate). Soil columns with suboxic and anoxic conditions performed poorly (i.e., less than 30% attenuation of moderately degradable TOrC) in comparison to oxic conditions (on average between 70-100% attenuation for the same compounds) within a residence time of three days. Given this dependency on redox conditions, it was investigated if key parameter-dependent rate constants are more suitable for contaminant transport modeling to properly capture the dynamic TOrC attenuation under field-scale conditions. Laboratory-derived first-order removal kinetics were determined for 19 TOrC under three different redox conditions and rate constants were applied to MAR field data. Our findings suggest that simplified first-order rate constants will most likely not provide any meaningful results if the target compounds exhibit redox dependent biotransformation behavior or if the intention is to exactly capture the decline in concentration over time and distance at field-scale MAR. However, if the intention is to calculate the percent removal after an extended time period and subsurface travel distance, simplified first-order rate constants seem to be sufficient to provide a first estimate on TOrC attenuation during MAR.

“…Removal rates of 72 and 26 % were achieved for hexavalent and trivalent chromium, respectively, and treated effluent met the Italian regulation for water reuse. (Patterson et al, 2012). Results showed that the anaerobic conditions of the aquifer were suitable for the biodegradation of NDMA with first-order kinetics.…”

A review of the literature published in 2012 on topics related to water reclamation and reuse is presented. This review is divided into the following sections: (1) General: extent of reuse, research needs, guidelines and monitoring, and health effects, (2) Treatment technologies: integrated process design, membrane treatment, membrane bioreactors, electrocoagulation, ion exchange and adsorption, wetlands, managed aquifer recharge, and (3) Planning and management: public acceptance and education, economics/pricing, water quality planning and management and project/case studies. It can be seen from this review that much of the treatment technology research has focused on membrane treatment, integrated designs and other innovative technologies.
