Previous studies showed that measures were required to control populations of E. coli and zebra mussel larva in water from the St. Lawrence. A system using slow sand filtration and an aerated pond was therefore installed at a farm on Île d'Orléans. Although this system has been proven to be effective for resolving both these problems, the sand filter can become clogged due to increased turbidity levels in the river at certain times of year and algal blooms in the water column above the filter. To manage this clogging risk, the project automated pumping based on water turbidity and cover the filter to prevent light from entering the water and thus reduce algal bloom. These control measures will improve technology transfer to other farmers who want to draw water from the river.
