“…COD and NO 3 -N can be provided by diffuse sewage sources and road runoff, which can be an important pollutant source due to the high runoff volumes that can be involved (e.g. Crabtree et al 2006;Pereira et al 2015). Both these sources may be significant in the Ribeira dos Covões catchment.…”

“…Heavy metals are typically associated with vehicular traffic and road runoff in urban situations (e.g. Crabtree et al 2006;Herrera 2007). In Ribeira dos Covões catchment, a complementary study of heavy metals in runoff collected from four roads provided direct evidence of the capacity of road runoff to generate heavy metal pollution in the catchment (Ferreira et al 2016c).…”

Dynamics of surface water quality driven by distinct urbanization patterns and storms in a Portuguese peri-urban catchment

Purpose Although the influences of urban land use on water quality have been widely investigated, the impacts of different urbanization patterns, particularly in Mediterranean environments, are not well understood. Focussing on a Portuguese peri-urban catchment with 40 % urban cover, this paper explores (1) the impact of areas with differing urban extent and storm drainage system on streamwater quality and (2) temporal variations driven by season and storm events of differing magnitude, intensity and antecedent weather. Materials and methods Water quality was assessed at the catchment outlet (E) and for three upstream tributaries: (1) Porto Bordalo (PB), 39 % urban with a new major road and piping of some overland flow from impervious surfaces directly into the stream; (2) Espírito Santo (ES), 49 % urban, mostly comprising detached houses surrounded by gardens, and with overland flow infiltrating into downslope pervious soils; and (3) Quinta (Q), 22 % urban with partial piping of overland flow from a recent enterprise park area. Water samples were collected at different stages in storm hydrograph responses to ten rainfall events from October 2011 to March 2013. The water quality variables analysed included chemical oxygen demand (COD), nutrients (Kjeldahl nitrogen [Nk-N], ammonium , nitrate [NO 3 -N] and total dissolved phosphorus (TDP) and heavy metals (Zn and Cu). Results and discussion Urban areas had great impact on COD, with the highest median concentrations in ES and the lowest in Q. In ES, fertilizing lawns and gardens may have been responsible for its higher median NO 3 -N concentrations. High concentrations of heavy metals were recorded in PB and Q, probably due to the piping of road runoff directly into the stream. Generally, higher pollutant concentrations were recorded in the first storm events after the summer drought due to the flushing of accumulated solutes and a lower dilution effect, with Nk-N and NH 4 -N exceeding water quality standards. Over the wet season, increasing soil moisture favoured greater flow connectivity between runoff processes from pollutant sources and the stream network, leading to a higher proportion of samples exceeding pollution thresholds. Conclusions No direct relationship was identified between urban extent and water quality, possibly due to the overriding impact of different storm drainage systems and flow connectivities of different urban patterns. Hydrological regime, linked to seasonal changes, also exerted a major influence on the water quality dynamics. Information on the spatiotemporal dynamics of pollutants, linked to different urban patterns and storm drainage systems, should help enable urban planners to minimize the adverse impacts of urbanization on aquatic ecosystems.

“…The tunnel is cleaned twice a year, and the spring cleaning coincided with the time of the planned study and had the advantage of being representative road runoff. Based on typical pollutant concentrations in runoff from Scandinavian (Petterson et al 1999;Roseth et al 2003;Westerlund 2005) and European roads (Boller 1997;Crabtree et al 2005), and typical concentration levels in the tunnel wash water (Roseth et al 2003), a wash water dilution of 1:6 (mixture A, Table 1) was used for the first event (April, E1). This resulted in metal concentrations that were generally lower than the road runoff values found in the literature.…”

A bioretention media is a stormwater treatment option designed to reduce peak runoff volumes and improve water quality through soil infiltration and plant mitigation. To investigate the heavy metal removal in a bioretention media in a cold climate setting, a small pilot sized bioretention box was built in Trondheim, Norway. The system was sized using the Prince Georges County bioretention design method from 1993. Three runoff events, created using historical data, were undertaken in April 2005 and then again in August 2005. Both the peak flow reduction and the total volume reduction were significantly lower in April compared to August. Peak flow reduction was 13% in April versus 26% in August and the total volume reduction was 13% in April versus 25% in August. Metal retention was good for both seasons with 90% mass reduction of zinc, 82% mass reduction of lead and 72% mass reduction of copper. Plant uptake of metals was documented between 2 to 7%; however adsorption and mechanical filtration through the mulch and soil column were the most dominant metal retention processes. The metal retention was independent of the selected hydraulic loading rates (equivalent to 1.4-7.5 mm h −1 precipitation) showing that variable inflow rates during this set of events did not affect the treatment efficiency of the system.

“…These are designed to confine pollutants in cases of spills, to control water flow during rainstorms, and to keep contaminants in runoff water isolated from other water bodies to protect surface and ground waters (SETRA 2007). Traffic pollutants include metals, mainly lead, cadmium, copper, and zinc (Youssef et al 1990;Stotz and Krauth 1994;Wu et al 1998; Barrett et al 1998;Legret and Pagotto 1999;Davis et al 2001;Bäckström et al 2003;Crabtree et al 2006;Zehetner et al 2009). Studies suggest that pond efficiency in removing pollutants is highly variable, affected by a complex array of factors including physicochemical features (Lee et al 1997b) and geographical location (Ye et al 2001;Peltier et al 2003;Clozel et al 2006;Pontier et al 2004;Stead-Dexter and Ward 2004;Hossain et al 2005).…”

Highway detention ponds can fill with sediments from runoff water loaded with trafficrelated materials. Sediment disposal is problematic and various protocols are currently studied, including phytoremediation. Here we present a preliminary study on four highway detention ponds in southern France to identify key sediment characteristics. Our objectives were to characterize metal content and physicochemical properties of the sediments and to evaluate the role of charophytes, which grow spontaneously in ponds, on metal lability. Vegetated and non-vegetated areas were compared. The lability of Mn, Cu, Zn, and Pb complexes was greater in the presence of charophytes. No variation in grain size composition was observed between non-vegetated and vegetated areas. These results may be useful to implement a phytoremediation strategy using those spontaneous charophytes. Our results suggest that local factors may impact sediment characteristics: for instance, strong gusts of wind, typical of southern France climate, may blow particles (some of them not related to traffic) in and out of detention ponds.
