    Notes: The eighteenth report of the Royal Commission on Environmental Pollution made no reference to any potential environmental impacts resulting from runoff pollution associated with transport activities. This paper identifies the magnitude and extent of pollution associated with discharges from various transport sources and identifies solids, metals, hydrocarbons, herbicides and de-icing agents as the principal contaminants of environmental concern. The impacts of these pollutants on the receiving water are reviewed. They are primarily associated with highways which have a high traffic density, and herbicides are considered to be the only potential and widespread hazard to groundwaters. Highway and airport runoff are shown to have both acute and chronic effects on biotic diversity and organism mortality rates, although these effects appear to be largely confined to reaches immediately downstream from the discharge outfalls.

    Notes: Partnership initiatives to address the problem of diffuse pollution from impermeable surface runoff within urban catchments are reviewed, with particular reference to mutual stakeholder duties and interests which are vested in the regulatory agencies, planning authorities, developers, water companies and highway agencies within the UK. The role of ‘sustainable urban-drainage systems’within integrated catchment-based approaches is considered in the context of the requirements of the EU Water Framework Directive and strategic river-basin management planning.

    Notes: Source control is regarded as a key principle in supporting concepts of sustainable management and integrated pollution control for diffuse non-point stormwater runoff, with infiltration procedures being a prime component of such source-control systems. The potential conflicts between the benefits of groundwater recharge and the risks to long-term groundwater quality uncertainties associated with infiltration disposal are considered. The long-term performance of a number of infiltration systems is reported in terms of their pollutant removal efficiencies, and the utility of an infiltration acceptability matrix approach is reviewed.

    Notes: [Auszug] Recent work2 has shown how these processes may be extended by methods of induction to arbitrarily moving electromagnetic multipoles. By integrating by parts successively until the Green's function emerges un-differentiated in the integrands and then carrying out the integration, concise and ...

    Notes: Abstract The top and bottom of two sediment cores collected from an urban receiving basin in NW London, and stormwater samples from the attendant catchment, have been analysed for their hydrocarbon content. In surface sediments, basal sediments and stormwater, total aliphatic hydrocarbon levels are 445–690 µg g−1 dry wt., 43–224 µg g−1 and 0.36–1.10 mg l−1, respectively; and total levels of polyaromatic hydrocarbons (PAHs) are 780–1 100 µg g−1, 310–640 µg g1 and 5.83–18.21 mg l−1, respectively. Biodegradation of aliphatics is assessed by phytane:n-C18 and pristane: n-C17 ratios. Hydrocarbon sources are determined from phytane: pristane ratios, odd: even carbon chain length ratios, the presence of an unresolved complex mixture, and by comparison of the amount of methyl-substituted PAH s with that of the parent compounds. Comparison of total levels between surface and basal sediments shows a 1 to 3 fold increase in total PAHs and a 3 to 10 fold increase in aliphatic hydrocarbons over a 120 year period.

    Notes: Abstract The increases in population and building density that occur as predominantly rural catchment areas become progressively urbanised can have a far-reaching effect on the hydrological cycle, and therefore on both the quantity and quality of water resources. The success of management strategies intended to alleviate the flooding problems and to prevent the degradation of water quality within and downstream of the urban area depends upon a thorough understanding of the sources of urban runoff pollution and the mechanisms by which pollutants are transported to watercourses. Particular care is necessary to ensure that any measures taken to mitigate the adverse effects of either flooding or pollution do not conflict with others in the same overall stormwater management plan.
