NOTES:
| |
---|---|
1Except for chromium (hex), all concentrations
listed for metallic substances shall be as "total metal," which shall be defined
as the value measured in a sample acidified to a pH value of two or less,
without prior filtration.
| |
2As determined on a composite sample taken
from the user's daily discharge over a typical operational and/or production
day.
| |
3As determined on a grab sample taken from
the user's discharge at any time during the daily operation and/or production
period.
|
Antibiotics
| |
Chemical compounds which, upon acidification, alkalinization, oxidation
or reduction, in the discharge or after admixture with wastewater and its
components in the POTW produce toxic, flammable or explosive compounds
| |
Pesticides, including algicides, fungicides, herbicides, insecticides,
rodenticides
| |
Polyaromatic hydrocarbons
| |
Viable pathogenic organisms from industrial process or hospital procedures
