Description
This report presents the results of a technical assessment of water quality trigger exceedances for total nitrogen, dissolved uranium and dissolved lithium at the Athabasca River at Old Fort monitoring station for the year 2012. The assessment was initiated under the Lower Athabasca Region Surface Water Quality Management Framework for the Lower Athabasca River and helps fulfill a commitment made in the Lower Athabasca Regional Plan to initiate a management response when annual assessments indicate triggers or limits have been exceeded. The monitoring results are found in the 2012 Status of Ambient Environmental Conditions Report. This water quality assessment completes the first two steps (verification and preliminary assessment) in the management response and identifies which water quality indicators will be moved into the investigation phase.
