A conventional pollutant is a term used in the USA to describe a water pollutant that is amenable to treatment by a municipal sewage treatment plant. A basic list of conventional pollutants is defined in the U.S. Clean Water Act. The list has been amended in regulations issued by the Environmental Protection Agency:
- biochemical oxygen demand (BOD)
- fecal coliform bacteria
- oil and grease
- pH (exceeding regulatory limits)
- total suspended solids (TSS).
The Secondary Treatment Regulation contains national discharge standards for BOD, pH and TSS, applicable to sewage treatment plants in the U.S.
Famous quotes containing the word conventional:
“A murderer is regarded by the conventional world as something almost monstrous, but a murderer to himself is only an ordinary man.... It is only if the murderer is a good man that he can be regarded as monstrous.”
—Graham Greene (1904–1991)
