AWWA WQTC50482

Viral contamination of groundwater is a major concern both to water service companies, which use groundwater as their raw source, and the public they serve. Viruses are typically more resistant to inactivation than most enteric bacteria and they may not be removed efficiently during land application of wastewater. Adsorption is one of the major factors in viral removal and persistence in soils. The comparative survival and adsorption of NV in soils suspended in groundwater has not been determined. Therefore, we determined the adsorption and persistence of NV in four soils suspended in groundwater: Cecil clay loam, Corolla sand, Ponzer organic muck, and Flushing Meadows sand loam. NV adsorption was compared to PV1 (strongly adsorbed) and MS2 (weakly adsorbed). These studies demonstrate that NV is not novel in its persistence and adsorption in groundwater and soil systems. Rather, it behaves similarly to PV1 and MS2. Includes 10 references, table, figures.
