MONITORING SUBMARINE TAILINGS OUTFALLS IN AN INCREASINGLY SKEPTICAL WORLD
Expanding mining activity in coastal areas has increased our awareness of the need for sound waste management practices for the disposal of mine tailings. Submarine Tailings Disposal (STD) into coastal waters is regaining acceptance as a viable alternative to land based systems for storing tailings. Because mine tailings disposed of in the ocean are often associated with high sedimentation rates, elevated suspended solids, metals and other priority toxins they can have severe impacts on the marine environment if not managed carefully. The complex nature of abiotic and biotic interactions in the oceans requires a scientific approach to managing tailings disposal in these often fragile coastal areas.
Environmental monitoring of STD and other outfalls must meet scientific rigor to effectively predict and mitigate any potential impacts to coastal areas. Possible monitoring strategies are discussed in relation coastal characteristics, including the role of numerical modeling, the need for baseline data, effective statistical designs, and sampling techniques for key STD monitoring parameters. Examples from worldwide projects are presented.
