Title: Environmental recovery in a marine ecosystem impacted by a sulfite process pulp mill

Recovery of an impacted marine ecosystem has been monitored by progressive advance of biologically distinguishable zones toward a waste discharge point from a pulp mill brought under specific pollution controls. The relative distribution of enchytraeid/tubificid oligochaetes monitored a 0.5-km retreat of a depauperated zone initially extending 1 km around the discharge point. Distribution and abundance of Fucus-epifaunal amphipods monitored recovery of a less impacted zone, particularly by a 7-km advance of a Peak of Opportunists point involving the species Allorchestes angusta. Shoreline organism diversity provided a biologically based estimate (approximately 12 km from the discharge source) of the region distinguishably influenced by the pulp mill effluent. (Refs. 10).
