The effluent of the Edmundston mill is discharged into the St John River after primary and secondary treatment. Since 1995, the releases of biochemical oxygen demand (BOD), total suspended solids (TSS) and AOX have been reduced and are now at low levels.

Biochemical Oxygen Demand (BOD)	3.86 kg/ADMT of pulp (M)
Total Suspended Solids (TSS)	7.42 kg/ADMT of pulp (M)
Absorbable Organic Halides (AOX)	1.00 kg/ADMT of pulp (M)
Water Usage¹	118 m³/ADMT of pulp (M)

M = the value is derived from direct measurements
