| Summary: | The discharge of sewage and wastewater into the Antarctic environment represents a serious and significant risk of environmental impacts that includes the introduction of non-native micro-organisms and pathogens, genetic pollution and accumulation of, and exposure to, contaminants. Wastewater discharges could lead to long term impacts on wildlife health, biodiversity and community structure in the vicinity of Antarctic stations. Treatment and disposal practices vary widely, as each Party to the Antarctic Treaty determines their own standards with varying interpretation of requirements under the Protocol on Environmental Protection. Further research and monitoring of the impacts of wastewater on Antarctic ecosystems will assist in quantifying the potential risks and impacts. Currently, no guidelines exist that describe permissible levels of bacteria, chemical and other contaminants being discharged from outfalls within the Treaty area, but their development would be beneficial in setting a baseline for monitoring. One of the highest priorities of the Committee for Environmental Protection (CEP) is addressing the introduction of non-native species. Wastewater discharge is a significant source of potential introductions, but advanced wastewater treatment could substantially reduce this and other associated risks. : Waste disposal Waste management Environmental monitoring |
