EXAM SCRIPT FINAL PAPER 2026 FULL
QUESTIONS AND CORRECT ANSWERS
◉ Industrial User
Answer: and non-domestic source which introduces pollutants into
a POTW
◉ Industrial Wastewater
Answer: Any non-domestric wastewater (excluding storm water)
◉ Mass Based Limits
Answer: Discharge limits based on allowable dry weight of pollutant
(lbs/day)
◉ Mass Emission Rate
Answer: The rate of discharge of the dry weight of a pollutant in
wastewater or air (lbs/day)
◉ Molarity
Answer: Mols/L
, ◉ Molecular Weight
Answer: Atomic weight of all atoms in a molecule
◉ National Pollutant Discharge Elimination System (NPDES)
Answer: The federal permitting program designed to control all
discharges of pollutants from point sources into US waterways
◉ National Prohibited Discharge Standards
Answer: Prohibitions, applicable to all nondomestic dischargers,
regarding the introduction of pollutants into POTWs
◉ Normality
Answer: A measure of concentration of a solution
◉ Oxidation-Reduction
Answer: Reactions involving the transfer of electrons, with oxidation
being the loss of electrons and reduction being the loss of electrons
and reduction being the gain of electrons. ORP, or oxidation-
reduction potential, is a qualitative measure of the state of oxidation
of compounds
