Abstract

Enteric viruses are one of the major concerns in water reclamation and reuse at Managed Aquifer Recharge (MAR) sites. In this study, the transport and fate of bacteriophages MS2, PRD1, and ΦX174 were studied in sediment and stormwater (SW) collected from a MAR site in Parafield, Australia. Column experiments were conducted using SW, stormwater in equilibrium with the aquifer sediment (EQ-SW), and two pore-water velocities (1 and 5 m day−1) to encompass expected behavior at the MAR site. The aquifer sediment removed >92.3% of these viruses under all of the considered MAR conditions. However, much greater virus removal (4.6 logs) occurred at the lower pore-water velocity and in EQ-SW that had a higher ionic strength and Ca2+ concentration. Virus removal was greatest for MS2, followed by PRD1, and then ΦX174 for a given physicochemical condition. The vast majority of the attached viruses were irreversibly attached or inactivated on the solid phase, and injection of Milli-Q water or beef extract at pH = 10 only mobilized a small fraction of attached viruses ( μs > kdet > μl, and katt was several orders of magnitude greater than μl. Therefore, current microbial risk assessment methods in the MAR guideline may be overly conservative in some instances. Interestingly, virus BTCs exhibited blocking behavior and the calculated solid surface area that contributed to the attachment was very small. Additional research is therefore warranted to study the potential influence of blocking on virus transport and potential implications for MAR guidelines.

Abstract

Groundwater resources that sustain small Indigenous communities in remote parts of northern Australia are often poorly characterised, in part due to their remoteness and the economics of undertaking field investigations. The Warruwi community on South Goulburn Island in the Northern Territory is completely reliant on groundwater for its livelihood. Recent consecutive poor wet seasons highlighted both: (i) the sensitivity of the island's water resources to short-term rainfall variability, and (ii) the inadequacy of the island's water infrastructure for meeting water demand during dry periods. An integrated approach was taken to underpin the longer-term water security for the community and to better characterise and quantify the island's water resources and infrastructure requirements. This involved: an airborne electromagnetic (AEM) survey supported by ground geophysics; a hydrogeological survey including environmental tracer analysis; and a desktop study including an annual groundwater balance. Spatial analyses of the AEM data, lithology, groundwater levels and salinity identified a thin (~20m), storage-limited unconfined freshwater `lens' system overlying a regional aquitard. Groundwater level analyses combined with tracer interpretation characterised a hydrodynamic flow system with short flow paths (, Open-Access Online Publication: March 03, 2023

Abstract

The article reports that United Nations Educational, Scientific and Cultural Organization (UNESCO) has published a book that showcases examples of an emerging solution in improving water security managed aquifer recharge (MAR). It mentions that MAR is coupled with water recycling, it can increase the productive use of urban storm water and wastewater, which reduces the pressure on traditional water sources (surface water and groundwater).
