The overall objective of this research program is to understand the impacts of the Baker Lake, NU, wastewater treatment system on environmental and human health, and develop recommendations for improving wastewater management in the community. The current wastewater treatment system in Baker Lake consists of a pond-wetland complex that ultimately discharges into Baker Lake. Baker Lake is important fish habitat and also provides the water supply for the community of Baker Lake. Wastewater accumulates in a small detention pond during the winter months (October – May), and then discharges in an uncontrolled manner into the wetland as it thaws during the spring freshet. This scenario is typical of many wetland treatment areas in Nunavut, and has been documented to contribute to poor levels of wastewater treatment that may pose a risk to both human and environmental health. The research program will involve an interdisciplinary team of researchers and will employ a holistic approach to characterize the impacts of the current wastewater treatment system on environmental and human health.
