A dye tracer study is being conducted at the Mapleton Water Pollution Control Plant today.
The Ministry of Environment is trying to understand the hydrologic haracteristics of the Conestogo River in the vicinity of its mixing with the effluent from the Mapleton Plan.
The study will be ongoing to 5pm today and the dye is non toxic.
However, it will turn the river pink from Mapleton, to Concession 8.
