Water Quality - Kouchibouguac
The Canadian Council of Ministers of the Environment (CCME) has designed a Water Quality Index (WQI) to translate complex water quality data into an overall integrated score from 0-100. This score is based on the number of measured variables, which have observations exceeding water quality thresholds (i.e., scope); the number of these exceedances in the dataset (i.e., frequency); and the magnitude by which the observations exceed the guidelines (i.e., amplitude). These water quality parameters are crucial indicators of the physical, chemical or biological conditions in aquatic systems and processes. The purpose of the water quality monitoring program at Kouchibouguac National Park is to use this index to calculate a score and evaluate the status of our freshwater ecosystems. The methods for this measure involve a once-a-month sampling, from May to November, of permanent stations in five tributaries: Kouchibouguacis River, Tweedie Brook, Black River, Rankin Brook, and Portage River. At each station, a number of water quality parameters are measured in situ as well as the collection of samples that are sent for laboratory analysis of chemical content three times a year in the Spring, Summer, and Fall to capture seasonal variation. In addition, ten key variables (i.e., total phosphorus, nitrate, dissolved oxygen, pH, total alkalinity, aluminium, calcium, total suspended solids, turbidity, total organic carbon) were selected to include in the WQI calculation in order to reflect the regional situation and account for possible natural or anthropogenic disturbances (e.g., eutrophication or oxygen deficits, acidification, land-use changes) related to deforestation, agriculture, and urbanization activities.
