In the context of waste discharge requirements on a mass basis, concentration and flow rate are key factors because they directly determine the total mass of pollutants being discharged into the environment. The concentration denotes how much of a specific pollutant is present in the wastewater, while the flow rate indicates the volume of wastewater being discharged over a certain period of time. By multiplying these two components, one can ascertain the total mass of the pollutant discharged, which is essential for compliance with environmental regulations.

Understanding this relationship is crucial for regulatory bodies and treatment facilities to ensure that they manage pollutants within the limits set for the health and safety of the environment. Inadequate consideration of either factor can lead to insufficient treatment or unintentional exceedance of discharge limits, potentially harming water quality and local ecosystems.

The other options, while they may include relevant information about wastewater characteristics, do not address the specifics of calculating discharge requirements on a mass basis in the same way that concentration and flow rate do.
