“…Hence, a median ionic strength is not representative for several sites or seasons. Winter maintenance practices, such as de-icing salt applications, generate chlorides and associated cations, in particular sodium and calcium, that can have an effect on the removal of heavy metals [49,50]. Thus, the ionic strength previously used in lab experiments does not reflect the amount and composition of the cations and anions of real stormwater runoff.…”

For the development of decentralized treatment systems for road runoff, the determination of pollutant removal capacities is essential. The aim of this study was to evaluate the impact of boundary conditions on the simultaneous removal of copper, nickel, and zinc by six sorbents used for urban stormwater treatment (i.e., granular activated alumina, anthracite, granular reactivated carbon, granular ferric hydroxide, calcium carbonate, and granular activated lignite). For batch experiments, capacities were determined at initial concentrations within the range of 2.5-180 mg/L with a rotary shaker. Further influences were investigated: the use of a horizontal shaker for concentrations of up to 1080 mg/L, a variation of the initial pH value (5 and 7), and the presence of a buffer. Furthermore, the influences of the filtration process on the capacities were studied. Kinetic experiments were conducted for contact times between 5 min and 120 min. Lab-scale column experiments with inflow concentrations of 2.5 mg/L (copper and nickel) and 5.0 mg/L (zinc) at an initial pH of 5 and a contact time of 11 min were performed for comparison. Selected experiments were subsequently carried out with changes in initial concentrations and contact time. One result is that it is essential to conduct batch experiments with the metals of interest. The capacities determined by column experiments deviated from batch experiments. Batch experiments under well-defined conditions can be used to evaluate different production batches. Column experiments give a more faithful capacity by considering realistic boundary conditions and should be preferred to determine efficiencies and service lives.

“…The causes of elevated trace metal concentrations, in response to the increased salt concentrations, have been attributed to cation exchange, and the presence of Cl and organic complexes (Amrhein et al, 1994;Lumsdon et al, 1995;Nelson et al, 2009;Brady and Weil, 2008).…”

“…Those studies largely focused on the concentration changes of Cd, Cu, Pb, and Zn in groundwater and soil solution in response to varied salt conditions (Backstrom et al, 2004;Menzies and Jacks, 1998;Nelson et al, 2009;Norrstrom and Jacks, 1998). There is an apparent lack of studies on the combined geochemical mechanisms that mobilize As, Pb, Hg, and other trace metals from a coastal aquifer and soils of a salted watershed.…”

“…With increased salt encroachment into the coastal aquifer due to the rising sea levels as well as groundwater overpumping, and increased winter deicing salt applications in northern watersheds, many previous studies have expressed concerns with regard to the release of the overall prevalent trace metals Cd, Cu, Pb, Hg, and Zn to the supply of drinking water, owing to the elevated salt concentration in a coastal aquifer and growing use of deicing salt in watersheds in the northern US, Europe, and Canada (Grassi and Netti, 2000;Protano et al, 2000;Barringer et al, 2007;Amrhein et al, 1994;Amrhein and Strong, 1990;Backstrom et al, 2004;Bauske and Goetz, 1993;Kelly et al, 2008;Nelson et al, 2009;Norrström and Jacks, 1998).

“…Elevated or fluctuating Cl − concentrations can directly damage aquatic ecosystems (19). Cl − may also mobilize heavy metals, phosphates, and other chemicals present in sediment (20). Treatment of waste high in Cl − is expensive because the Cl − is not easily removed by chemical or biological processes once it is in solution (21); thus, high Cl − concentrations may also increase costs for downstream water users (e.g., industrial or drinking water facilities).…”

Concern has been raised in the scientific literature about the environmental implications of extracting natural gas from deep shale formations, and published studies suggest that shale gas development may affect local groundwater quality. The potential for surface water quality degradation has been discussed in prior work, although no empirical analysis of this issue has been published. The potential for large-scale surface water quality degradation has affected regulatory approaches to shale gas development in some US states, despite the dearth of evidence. This paper conducts a large-scale examination of the extent to which shale gas development activities affect surface water quality. Focusing on the Marcellus Shale in Pennsylvania, we estimate the effect of shale gas wells and the release of treated shale gas waste by permitted treatment facilities on observed downstream concentrations of chloride (Cl − ) and total suspended solids (TSS), controlling for other factors. Results suggest that (i) the treatment of shale gas waste by treatment plants in a watershed raises downstream Cl − concentrations but not TSS concentrations, and (ii) the presence of shale gas wells in a watershed raises downstream TSS concentrations but not Cl − concentrations. These results can inform future voluntary measures taken by shale gas operators and policy approaches taken by regulators to protect surface water quality as the scale of this economically important activity increases.unconventional gas | water pollution | econometric analysis | panel data
