Infiltration of urban stormwater runoff is becoming more common in many areas of the United States and throughout the world. For infiltration to be successful as a stormwater management strategy, however, it is imperative that suitable sites be identified and their lifespan and maintenance requirements be predicted. Infiltrating in unsuitable areas can result in groundwater contamination and associated impairment of beneficial uses. This paper reviews several categories of urban stormwater pollutants and their groundwater contamination potential. Case studies, both from the field and the laboratory, then are presented to summarize information regarding the potential factors affecting pollutant transport through the vadose zone. Finally, two levels of prediction models to assess the susceptibility of groundwater contamination from urban stormwater infiltration are presented.

“…These filtration systems have proven their efficiency in removal of organic matter, nutrients and pathogens (Stevik et al 1999;Jenssen et al 2005;Van Cuyk & Siegrist 2007). However, hydraulic failures in infiltration systems caused by clogging have been observed after long time of operation, leading to ponding, odors and reduced treatment performance (Kristiansen 1981;Jenssen & Siegrist 1990).…”

Enhanced treatment of septic tank effluent can improve the hydraulic function and performance of infiltration systems and constructed wetlands. By intermittent spray application of septic tank effluent onto a coarse-grained filter media, an unsaturated flow regime beneficial for pathogen removal is created. A column filtration study showed an increase in PRD-1 removal by time of operation with corresponding biofilm accumulation in the filter material. The same increased removal was observed for 1 mum polystyrene beads, irrespective of their hydrophilic/hydrophobic surface properties. A control experiment with sorption of 1 mum hydrophobic and hydrophilic polystyrene beads to different glass surfaces with hydrophobic and hydrophilic properties indicate that mechanisms other than hydrophobic interactions may govern the rate of attachment to the filter media. For a given volumetric flow-rate in the columns, the presence of biofilm altered the hydrodynamic characteristics and this resulted in increased retention time and particle removal.

“…For example, soil clogging at the soil IS can yield an unsaturated soil profile below that is aerobic and has long retention times during film flow over soil grains. This can enhance sorption, biodegradation, and natural disinfection processes (Van Cuyk and Siegrist, 2007;Washington State Department of Health, 2002). However, if soil clogging is too intensive, it can reduce the hydraulic capacity below the operational loading rate and cause hydraulic malfunctions.…”

Onsite wastewater systems, widely used in the United States and abroad, often rely on infiltration of effluents into native soils for tertiary treatment and natural disinfection. The processes that govern soil clogging and hydraulic performance during infiltration into soil are complex and involve a dynamic interaction between physical, chemical, and biological processes. The authors link the development of soil clogging in onsite systems with the fundamental physical, chemical, and microbial processes that can occur during wastewater reclamation in soil environments. They provide a critical review of onsite wastewater systems, outlining the different types of wastewater-induced soil clogging, clogging locations, and clogging materials. The authors then focus on the influence of oxygen concentration on clogging and the environmental conditions that stimulate the accumulation of organic materials from microbial metabolism. Correlations are made between observational data in porous media studies and microbial metabolism. The objective of this review is to increase understanding of the processes that govern hydraulic performance of onsite wastewater systems during effluent infiltration and potentially improve system design and operation.
