“…A more thorough review of this phase of the investigation is given in Pitt et al (2004). Metalparticulate association tests using Chelex-100 resin revealed that more than 90% of the filterable forms of calcium, magnesium, potassium, iron, and zinc were in ionic forms, with very little colloidal, or other bound forms.…”

In the NURP studies (EPA, 1983), copper, lead, and zinc were detected in more than 90% of storm water samples from residential, commercial, and light industrial sites. The National Stormwater Quality Database (NSQD) is an update of the NURP data and has been developed from the monitoring data collected by MS4s (Municipal Separate Storm Sewer Systems) over the past decade (Pitt, et al 2004). This data set (summarized in Table 2) highlights the important effect of land use and source areas (parking areas, vehicle service stations, rooftops, streets, landscaped areas, etc.)…”

This 3-year study was funded by the Water Environment Research Foundation (WERF) (Johnson, et al. 2003) to investigate innovative heavy metal removal from stormwater. During this research, two major areas of heavy metal control were selected for in-depth investigation: media filters and swales. This presentation will focus on the filter tests. The test stormwater used for most of the laboratory tests was collected from a campus parking lot at the University of Alabama during many storm events. The characteristics of the stormwater indicated that the most prevalent metals detected in the runoff were iron, zinc, copper and small amounts of particulate bound lead. Ranges of the metals were within national ranges reported by other studies. The results emphasize the importance of characterizing the stormwater before selecting a treatment media since the type and quantity of metals, pH, and other runoff characteristics can vary a great deal between sites and can affect the pollutant removal characteristics. In the laboratory-scale filter studies, twelve media were chosen for initial evaluation. Equilibrium and kinetic studies were completed to assess their performance in capturing metals from stormwater. Twelve media were initially evaluated by means of batch equilibrium and kinetic tests to compare the rate and extent of metals capture. The three best performing media: peat-sand mix, compost, and zeolite, were then selected for an in-depth column studies using parallel upflow columns in packed media beds. Metal removal efficiency was examined for different rates of flow and influent conditions. Upflow columns proved more effective than downflow columns in the control of detention time, reduction in clogging of the media by solids, and associated head loss in the column. Studies on the effect of anaerobiosis on metal retention by filter systems indicated that heavy metals were not mobilized from filter systems under anaerobic conditions. However, some nutrients were lost after the media became anaerobic. It was found that metal retention by the filters was not different from what was observed in oxygenated environments. Tests also indicate that the heavy metals of concern remain strongly bound to the particulates during long exposures at the extreme pH conditions likely to occur in receiving water sediments. TCLP (leachability) tests were also performed on spent media to assess disposal options, with results indicating that traditional, non-hazardous-waste disposal should be acceptable for most stormwater applications.

Four types of permeable pavements were monitored at the Edison Environmental Center in Edison, New Jersey, for three water quality indicator organisms consisting of fecal coliform, enterococci, and Escherichia coli. This study expands a previously published result based on less than a year of available data. The current study reflects nearly 5 years of data collection with efforts focusing on collection of data in all four seasons to analyze seasonal effects and to understand the effects of pH on infiltrate concentrations. All three indicators were detected in infiltrates from all four permeable surfaces and as well as asphalt and roof runoff. Seasonally, the infiltrate during winter had fewer detections and lower enumerations and was most often significantly different than surface infiltrate and runoff for the other seasons. More significant concentration reductions were observed in summer and fall, and the lowest reduction was observed in winter. Pervious Asphalt treatment removed the most microorganisms for all three indicator organisms. A permeable interlocking concrete pavement (PICP) that was a replacement for pervious concrete during the study performed better than the original PICP most likely due to smaller gap spacing (8 mm compared to 12.7 mm) and correspondingly smaller specified surface aggregate compared to the original PICP. Percent concentration removal reductions based on geometric means were 89% or greater for PC, PA, and PICP for fecal coliform; 75% or better for PC, PA and PICP for E. coli; and 95% or greater for PC and PA for enterococci, while there were no annual removals for enterococci for original or new PICP nor removals for E. coli for original PICP and minimal removal for fecal coliform for original PICP. The major sources of fecal indicators in the stormwater runoff were most likely from the feces of deer, geese, and other wild animals. Practitioner Points• The infiltrate during winter had fewer detections and lower enumerations and was most often significantly different than surface infiltrate and runoff for the other seasons.
