cohesiveness of a team‚ Nut Island would be a good example. They worked together and enjoyed what they did at the sewage plant. Employees worked overtime without being paid for it and without complaining. They used everyone’s skills to take care of the plant and the plant equipment. The Nut Island disaster occurred because senior management paid little or no attention to the remote team at the sewage plant. They assumed that the staff knew what it was doing and would keep operations going‚ no matter what

2006 Q4 a) The greatest decline took place between 1965 and 1970. 700‚000 metric tons - 200‚000 metric tons = 500‚000 metric tons 500‚000 metric tons/5 years = 100‚000 metric tons per year the gorundfish harvest depleted by aproximately 100 thousand metric tons per year between 1965 and 1970. b) Bottom trawling is the act of scraping the bottom of a fishing area with a large net in order to catch fish. The net‚ however‚ catches more than the intended product. The nets destroy the bottom vegetation

She mentions that the sewage water is flushed out into the ocean. That Antigua doesn’t have a working sewage system. She also mentions how the lobsters that are eaten there are grown in Antigua‚ then shipped to the U.S.‚ then shipped back down for the tourists to consume. In mentioning this she is able to portray how

DEFINITION ANAEROBIC POND Anaerobic ponds are deep treatment ponds that exclude oxygen and encourage the growth of bacteria‚ which break down the effluent. It is in the anaerobic pond that the effluent begins breaking down in the absence of oxygen "anaerobically". The anaerobic pond acts like an uncovered septic tank. Anaerobic bacteria break down the organic matter in the effluent‚ releasing methane and carbon dioxide. Sludge is deposited on the bottom and a crust forms on the surface as show in

This resulted in the common practice of flushing pharmaceuticals into the sewage system and throwing them into the trash…Once in the domestic sewage‚ it is the responsibility of the sewage treatment plant to remove pollutants from the wastewater. Wastewater treatment plants‚ however‚ are designed primarily for the removal and treatment of natural human excrements and not the various

Since all natural waterways contain bacteria and nutrients‚ almost any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above). Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests

Water pollution is a serious matter‚ and can be defined as a problem. Poor water quality is just another way of saying water pollution. Water pollution is when one or more substances build up in water to such an extent‚ that several problems for animals and humans develop. Rivers‚ lakes‚ oceans‚ and other inland waters are able to naturally clean up certain amounts of the pollution by dispersing them harmlessly. Water pollution depends on the quantities: how much of the polluting substance is released
