『Abstract
The infrastructure (roads, sidewalk, commercial and residential
structures) added during the land development and urbanisation
process is designed to collect precipitation and convey it out
of the watershed, typically in existing surface water channels,
such as streams and rivers. The quality of surface water, seepage
water and ground water is influenced by pollutants that collect
on impervious surfaces and that are carried by urban storm water
runoff. heavy metals, e.g. lead (Pb), zinc (Zn), copper (Cu),
cadmium (Cd), polycyclic aromatic hydrocarbons (PAH), mineral
oil hydrocarbons (MOH) and readily soluble salts in runoff, contribute
to the degradation of water. An intensive literature search on
the distribution and concentration of the surface-dependent runoff
water has been compiled. Concentration variations of several pollutants
derived from different surfaces have been averaged. More than
300 references providing about 1300 data for different pollutants
culminate in a representative concentration matrix consisting
of medians and extreme values. This matrix can be applied to long-term
valuations and numerical modelling of storm water treatment facilities.
