WATER QUALITY DEGRADATION DUE TO NON-POINT POLLUTION FROM URBAN SOURCES
A study of the concentrations of cadmium and lead in the Christiana River in the Newark, Delaware, area showed that lead pollution originates from airborne automotive exhausts, while cadmium pollution originates from surface stormwater runoff. Four complete storm events were sampled for streamwater degradation analysis at five different sampling stations. Stream sediments and soils suspended during a storm event have significant adsorption capacity. Hydraulic dispersion and stochastic models are used to describe stream responses to storm events.
