“…In previous stormwater analyses at the OMB site, we observed a peak SC of 124 mS cm 71 with a storm event mean of 32 mS cm 71 in runoff from a snow event in which roads were managed with salt (Camponelli et al 2010). These values exceed the SC in almost all of our samples, suggesting that the concentrations of road salt in winter runoff are sufficient to explain the magnitude of salt enrichment observed at both sites.…”

We investigated the spatial and temporal distribution of chloride and conductivity in a long hydroperiod retention pond and two short hydroperiod detention ponds. In both cases we observed greatly elevated conductivities in surface and ground waters with peak conductivities exceeding 45 mS cm 71 in the retention pond and 25 mS cm 71 in one detention pond. Pond ground water conductivity remained highly elevated into the summer months and never declined to local stream conductivity levels. Conductivity and chloride concentrations were also elevated in floodplains adjacent to all ponds throughout the year. First order streams draining the detention pond floodplain were consistently elevated in conductivity and were a year-round net source of ions to the second order stream into which they flowed. These results indicate that both short and long hydroperiod stormwater ponds have the potential to serve as long-term, year round sources of chloride to adjacent surface and ground waters.

“…Camponelli et al (2010) found that Cu and Zn partitioned largely in the particulate phase of runoff coming from a boulevard in Baltimore country with 45,575 annual average daily traffics. However, Mangani et al (2005) found that Zn, Cu, and Pb were mainly associated with the dissolved fraction.…”

International audienceThe concentrations of heavy metals in water, sediments, soil, roots, and shoots of five aquatic macrophytes species (Oenanthe sp., Juncus sp., Typha sp., Callitriche sp.1, and Callitriche sp.2) collected from a detention pond receiving stormwater runoff coming from a highway were measured to ascertain whether plants organs are characterized by differential accumulations and to evaluate the potential of the plant species as bioindicators of heavy metal pollution in urban stormwater runoff. Heavy metals considered for water and sediment analysis were Cd, Cr, Cu, Ni, Pb, Zn, and As. Heavy metals considered for plant and soil analysis were Cd, Ni, and Zn. The metal concentrations in water, sediments, plants, and corresponding soil showed that the studied site is contaminated by heavy metals, probably due to the road traffic. Results also showed that plant roots had higher metal content than aboveground tissues. The floating plants displayed higher metal accumulation than the three other rooted plants. Heavy metal concentrations measured in the organs of the rooted plants increased when metal concentrations measured in the soil increased. The highest metal bioconcentration factors (BCF) were obtained for cadmium and nickel accumulation by Typha sp. (BCF = 1.3 and 0.8, respectively) and zinc accumulation by Juncus sp. (BCF = 4.8). Our results underline the potential use of such plant species for heavy metal biomonitoring in water, sediments, and soil

“…These pollutants may originate from motorized vehicle emissions, automobile tires, brake pads, corrosion of pavement, chemical deposition on or near the pavement surface and anthropogenic activities [1,4]. On the other hand, since impervious surfaces such as roofs and roads dominate the land cover of urbanized areas, cities suffer from increased and more intense runoff, reduced groundwater recharge and runoff water quality [5], increased peak flows [6] and hydrological, physico-chemical and consequent biological disturbance of the receiving waters [7,8].…”

Increase of impervious surfaces in urban area followed with increases in runoff volume and peak flow, leads to increase in urban storm water pollution. The polluted runoff has many adverse impacts on human life and environment. For that reason, the aim of this study was to investigate the efficiency of nano iron oxide coated sand with and without magnetic field in treatment of urban runoff. In present work, synthetic urban runoff was treated in continuous separate columns system which was filled with nano iron oxide coated sand with and without magnetic field. Several experimental parameters such as heavy metals, turbidity, pH, nitrate and phosphate were controlled for investigate of system efficiency. The prepared column materials were characterized with Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDXA) instruments. SEM and EDXA analyses proved that the sand has been coated with nano iron oxide (Fe3O4) successfully. The results of SEM and EDXA instruments well demonstrate the formation of nano iron oxide (Fe3O4) on sand particle. Removal efficiency without magnetic field for turbidity; Pb, Zn, Cd and PO4 were observed to be 90.8%, 73.3%, 75.8%, 85.6% and 67.5%, respectively. When magnetic field was applied, the removal efficiency for turbidity, Pb, Zn, Cd and PO4 was increased to 95.7%, 89.5%, 79.9%, 91.5% and 75.6% respectively. In addition, it was observed that coated sand and magnetic field was not able to remove NO3 ions. Statistical analyses of data indicated that there was a significant difference between removals of pollutants in two tested columns. Results of this study well demonstrate the efficiency of nanosized iron oxide-coated sand in treatment of urban runoff quality; upon 75% of pollutants could be removed. In addition, in the case of magnetic field system efficiency can be improved significantly.
