Tim Kuntz, left, and Nikki Thackeray of the Grand River Conservation Authority wade across the river near Blair while taking measurements of temperature, dissolved oxygen, conductivity and pH.
The pair were trying to determine whether a nearby water source in Blair was skewing the data collected by a continuous monitoring station. The GRCA has a series of seven of these stations that produce water quality data that is posted on their website in real time.
From the website:
"Real-time water quality information is collected to aid in the day to day decisions related to the operation of water control structures operated by the GRCA. This information is also used to report on current water quality conditions in specific river reaches and to calibrate and verify water quality models used for long range watershed planning. The real-time water quality network began operation in 1985."
