Monthly Average Concentration definition

Monthly Average Concentration means the arithmetic mean of all Daily Concentrations of a contaminant in the effluent sampled or measured, or both, during a calendar month;
Monthly Average Concentration means the arithmetic mean of measurements made during the month.
Monthly Average Concentration means the arithmetic average (proportional to flow) of all daily determinations of concentration made during a calendar month.
