“…In a French study (Legret and Pagotto 1999), Pb was, again, found to appear mostly in the particulate form (91%), but the other metals were usually dissolved. Kim et al 2005a) also reported that most of the Pb found in runoff samples was in the particulate phase, Ni was approximately the same as in the particulate phase, while Cu and Zn were predominantly present in the dissolved phase. In a particular storm event dissolved Cu and Zn concentrations were approximately 10 and 36 times greater than in the particulate phase.…”

“…The continuous input of material from traffic insures a continual increase in the cumulative constituent load throughout the duration of the storm event. Kim et al (2005a) noted that most metals exhibited first flush on concentration and mass basis. The range of metal concentrations from early stages of a storm compared to the final stages of the storm can be tenfold.…”

Highway runoff often is a significant non-point pollution source. Though it has been extensively studied there are still open questions regarding the identity and mutual influences of the factors affecting pollutant concentrations in road runoff. This review starts with a description of the main pollutants (heavy metals, refractory organics and suspended matter), then it analyzes interactions existing between them and their fractionation between the particulate and dissolved phases. The third section examines the sources of pollution, being: vehicles which contribute fluid and solid pollutants, roads which contribute suspended solids, and dry and wet atmospheric deposition which is influenced by adjacent land-uses. The last section discusses the importance of the factors affecting road runoff quality, the main of which are traffic, rainfall, local conditions (climate and land use) and highway characteristics. The review reveals that conclusions derived from existing data are often ambiguous and significant knowledge gaps still exist.

“…Distinctly elevated metal levels have been reported for such runoff waters (e.g. Kim et al 2005a). The storm event on 22/1/07 (sampled in three sequential parts: #9, #10 and #11, Table 2) displayed a typical pattern of initial high intensity (as measured by runoff flow rate) followed by declining intensity during the later part of the storm.…”

The aqueous mobility and potential bioavailability of metals and metalloids in road runoff in a 'wetdry' tropical location were assessed by analysing metal and metalloid concentrations in particulate, total dissolved and labile dissolved phases in runoff waters. Road-derived Al, Cu, Pb, Sb and Zn concentrations were substantially elevated in runoff when compared to receiving creek waters. Median dissolved concentrations in road runoff exceeded those in creek waters by up to an order of magnitude. Leaching experiments of road sediments confirmed that several metals and metalloids were released in high concentrations from road sediments. Labile Zn and Cu concentrations measured by diffusion gradients in thin films (DGT) showed that almost all dissolved Zn and up to half of dissolved Cu in runoff waters and in road sediment leachate were potentially bioavailable. Comparisons of dissolved metal concentrations in receiving waters affected by road runoff with ecosystem guideline levels, indicated a risk of reaching toxic levels of Cu and Zn in the receiving waters in the absence of adequate treatment or dilution. Low dilution rates of road runoff are likely to occur during late 'dry' season/early 'wet' season storms which have the potential to produce high metal concentrations derived from long periods of accumulation of road sediment at a time when creek flow rates are at their annual minimum.

“…The buildup depends on the ADD, land use, wind speed and traffic. Wash off may be a function of rainfall intensity and other factors (Kim et al 2005(Kim et al , 2006. Few researchers determined the effect of the antecedent dry period in their study of stormwater discharge (Saget et al 1996;Lee et al 2002).…”

Urbanization involving replacement of previous areas with impervious surfaces and drainage channel modifications results in increased runoff volume leading to flooding and also in deteriorating the quality of the stormwater runoff. An effective and efficient stormwater management is needed in the urban areas for mitigating the impacts and overcoming the problems associated with the urban stormwater. An attempt has been made in the present study to investigate the relationships between stormwater quality and five different land uses for the Patiala city of Punjab State. Stormwater samples collected from these locations, between April 2010 and March 2011, were analyzed for various organic and inorganic water quality parameters and heavy metals. Inter-parameter relationships studied provided vital information in deciding upon the treatment units most likely to be suitable for that particular sub-watershed. Multiple regression modeling helped in assessment of water quality parameters and predicting the quality well before actually analyzing the parameters and thus aided in developing treatment schemes suitable for taking care of the stormwater quality even under worst set of conditions. The outcomes of the research study effectively contributed toward conceptualizing a decentralized stormwater treatment system that would be capable of coping with the stormwater runoff-associated problems faced by the city and can serve as a model for other underdeveloped and developing cities having improper stormwater management facilities.
