“…The study, however, did not address the effects of salts on soil structure, and did not isolate the effects of organic matter, such as compost. Other studies have investigated the impacts of deicing salts on the ability of the soil to trap and retain metal pollutants (Nelson et al 2006(Nelson et al , 2009Peltier et al 2010;Peters 2009;Ramakrishna and Viraraghavan 2005).…”

Bio(in)filtration systems are constructed using engineered media which may or may not contain supplemental organic matter and clay-sized particles. They often are sited near transportation facilities, such as parking lot traffic islands and potentially along residential and commercial streets. Their location near transportation-related facilities, however, leaves them vulnerable to being used to store salt-laden snow during the winter months. During snowmelt times, the salt percolates through the media with the water and potentially reacts with the media.Many studies have shown that both sodium and chloride are poorly removed by filtration media. In addition, sodium-based salts can affect soil structure by internal particle movement, cementation, particle agglomeration, and ion exchange. This preliminary study focused on the effect of sodium chloride loadings on two engineered soils, one with and one without compost and both with clay-sized particles. For similar salt loadings, the flow rate decrease was substantially greater for the compost-amended soil than for the soil only. This indicates that the compost reacted with either the sodium or chloride, affecting the flow rate. This is further confirmed because mercury intrusion porosimetry testing did not show a reduced median pore size as would be expected if the clays had destabilized. In addition, the sodium loadings resulted in the loss of zinc from both media, indicating that the winter salt loading had the potential to cause of release of previously-trapped pollutants, such as metals.

Bio(in)filtration systems are constructed using engineered media which may or may not contain additional organic matter and clay-sized particles. They often are located near lower-pollutantgenerating transportation facilities, such as parking lot traffic islands and potentially along residential and commercial streets. Their location along transportation corridors or in parking lots, however, leaves them vulnerable to use as a salt-laden snow storage and melt location during the winter months. During melting, the salt percolates through the media with the water through the device, potentially reacting with the media.Many studies have shown that both sodium and chloride are poorly removed by filtration media. In addition, sodium-based salts can affect soil structure by internal particle movement, cementation, particle agglomeration, and ion exchange. This seed grant study focused on the effect of sodium chloride loading on two engineered soils, one with and one without compost. For similar salt loadings, the decrease in flow rate through the media was substantially greater for the one with compost added than for the soil only. This indicates that compost s reactivity with either the sodium or chloride also affected the flow rate, especially since porosimetry testing did not show a reduced median pore size as would be expected if the clays had destabilized. In addition, the sodium loadings resulted in the loss of zinc from both media, indicating that the winter salt loading had the potential to cause of release of previously-trapped pollutants, such as metals.
