Concerns
The water quality of Goulais River is not actively part of the Ontario Government's Provincial (Stream) Water Quality Monitoring Program Network (PWQMN), and hasn't been since 1990. According to the official database, there are 3 historical sites on the Goulais River: 1) one at the bridge in Searchmont on Hwy 532 that ran between 1972 and 1973 2) one at the bridge in Goulais on Hwy 17 that ran between 1973 and 1990 3) one at the mouth of Goulais Bay that ran between 1972 and 1987. Additionally, the recent Environmental Registry of notice for an Environmental Compliance Approval submitted by Searchmont Ski Resort included an independent-led sampling program that took monthly samples at 2 sites on the river over a 16-month period for a total of 20 sampling events in total, with only 1 one summer of data. Results show unexplained spikes, and Phosphorus exceeding the Provincial Water Quality Objectives. With the potential introduction of treated effluent sewage waste into Goulais River, the community is stepping forward to take an active part in stewarding and monitoring the quality of Goulais River. Regardless if the wastewater treatment plant is approved or not, we plan to continue our program well into the future to protect and sustain this sacred water way for generations to come.

Sampling frequency
Weekly Our program aims to test all parameters included in the Water Rangers Freshwater Kits on a weekly basis and on specific time schedule for each site between April/May to November. Our monthly sampling for total phosphorus and nitrates is being analyzed under NR CAN's Great Lakes Forestry Centre lab. We will also be testing for E.Coli on a bi-weekly basis with support from Algoma University's NORDIK Institute. We also plan to support testing at additional sites along Goulais River that are not currently included in our core dataset open for public participation. Any additional sites will be logged within a separate dataset under our organization and everyone is welcome and encouraged to follow the dataset, and review and share the results!
