- Secondary diffuse pollution may originate from long term uncontrolled or aban-

doned point sources. Being dispersed from point source needs diffuse pollution
management even after the termination of the pint source.

Campbell et al. (2004) have listed pollutants of concern originating from diffuse
sources. Toxic chemicals both inorganic (metals and salts) and organic (polycyclic
aromatic hydrocarbons and solvents) are the most serious pollutants in the runoff
