aX-ray Diffraction (XRD) technique was used. 1g of the sample was ground to <10 µm in a McCrone micronizing mill under ethanol and the resulting slurries were oven dried at 60 °C then thoroughly mixed with an agate mortar and pestle before being lightly back pressed into stainless steel sample holders for XRD analysis. XRD patterns were recorded with a PANalytical X'Pert Pro Multi-Purpose Diffractometer using Fe filtered Co Ka radiation, 1/4° divergence slit, 1/2° anti-scatter slit and fast X'Celerator Si strip detector. The diffraction patterns were recorded in steps of 0.016° 2 theta with a 0.4 second counting time per step and logged to data files for analysis.b X-ray fluorescence (XRF) technique was used. Approximately 1g of each oven-dried sample (105 °C) was accurately weighed with 4 g of 12-22 lithium borate flux. The mixtures were fused at 1050 °C in a Pt/Au crucible for 20 minutes then poured into a 32 mm Pt/Au mold heated to a similar temperature. The melt was cooled quickly over a compressed air stream and the resulting glass disks were analyzed on a PANalytical Axios Advanced wavelength dispersive XRF system using the in-house Silicates program. c Reverse Aqua Regia Acid Digest and Inductively Coupled Plasma Optical Emission Spectrometry. d Dry sieving

Figure S1. (A) City of Salisbury water harvesting facilities in the Parafield area, identifying the location of wells at the aquifer storage, transfer, and recovery (ASTR) and Parafield aquifer storage and recovery (ASR) sites (Kremer et al., 2008). (B) City of Mitcham wetland project in the Urrbrae area which was built to resolve a flooding problem (Mitcham, 2005).

Figure S4. The observed breakthrough concentrations of ΦX174, MS2, and PRD1 viruses during Phases I and II for the experiments conducted at solution chemistries of SW or EQ-SW at velocities of 1 or 5 m day-1. Note that the y-axis is plotted in normal scale instead of log scale as in Figure 1 to show the virus blocking behavior.
