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.

Famous quotes containing the word conventional:

    Westminster Abbey is nature crystallized into a conventional form by man, with his sorrows, his joys, his failures, and his seeking for the Great Spirit. It is a frozen requiem, with a nation’s prayer ever in dumb music ascending.
    M. E. W. Sherwood (1826–1903)
