The primary goal of the Clean Water Act is to protect sources of municipal drinking water from contamination and overuse. In order to properly protect drinking water, we need to understand what is going on in the surrounding watershed - both above ground as surface water and below ground as groundwater. The Assessment Report is a locally developed, technical document that provides the scientific foundation for the source protection planning process and was the foundation of the development of the Source Protection Plan. One of its objectives is to identify activities that would be significant drinking water threats as defined in the Tables of Drinking Water Threats (2 mb).

- Revisions to the number of existing significant threat activities following field investigations in Mattawa and the Callander Issue Contributing Area (ICA);
- Text changes to the work plan for the Callander Issue Contributing Area to reflect completion of a phosphorus budget and identification of the need to refine the ICA boundaries to incorporate flow direction using recently acquired elevation data; and
