This report aims to describe and discuss the impacts of direct sewage and wastewater discharge in Antarctica and the available treatment options, with specific reference to Scott Base. The information requited to achieve this has been obtained from a variety of resources, predominantly the reports and journals published by researchers who have studied the effects of sewage and wastewater disposal. The impacts of sewage and wastewater disposal ale shown to be localised in the areas of Antarctic stations. Research also shows that the effects on the marine environment similar in most regions. Although the scale of many of these effects is unknown, the potential risk they pose to the Antalttic marine environment is highly significant. The major issue is that sewage and wastewater released into these areas contain microorganisms and chemical substances that have the potential to persist and degrade the health Of receiving water bodies and ecosystems. The consequences of this are adverse ecological effects on the local environment. The Telease of large volumes of untrunted sewage into the Antarctic marine environment creates a source of persistent organic matter, bacterial and viral agents. Many of these are potential disease-causing agents for indigenous wildlife. Scientific results indicate collectively that treatment sites are necessary because of this impact and the potential for much more. Recommendations for the implementation of particular treatment options at Scott Base are made based on these results.
