| Abstract |
Five wastes from United States, Canadian, and foreign commercial vessels were studied at the Duluth-Superior Harbor during late 1973: Bilge water, non-oily ballast water, sewage, garbage/refuse, and dunnage. Vessels generate bilge water at about 6,650 liters/hour with an average oil content of about 225 milligrams/liter. Waste oil which is apparently discharged to bilges (about 600 grams/hour) appears more consistent than either of these two parameters. Bilge water is a substantial pollution problem: On the average about 40 liters (10 gallons) of oil may be discharged during each day a vessel spends in the harbor. Although containing about twice the common water quality contaminants as the harbor waters, ballast water is not a significant environmental problem. Large quantities are, however, discharged: About 9,000 metric tons/visit by lake and bulk carriers. Sewage is apparently generated onboard vessels consistent with accepted design rates (100 gallons/man/day). |
