Conventional Pollutant

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.

    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.
