Hi All
this one come out the other day regarding Loc Bromont done a few years ago. sound like all still going well, great endosement

The 2021 summer season is now over and the time has come to take stock. This season closes the 4th year of monitoring since the application of the Phoslock® treatment in the fall of 2017. We will remember this hot and very dry summer when the water quality of Bromont Lake was, after all, quite good. . Indeed, for the period from June to August, we again notice this year, average measurements of the transparency of the water higher than in 2017. Between the end of July and mid-August, the presence of a few flowers However, cyanobacteria water decreased the average water transparency for the month of August compared to 2019 and 2020.Despite this episode, the number of cyanobacteria blooms, from May to October, was similar to previous years (22 days in 2021, 20 days in 2020 and 28 days in 2019) and remains significantly lower than in 2017. before processing Phoslock® (101 days). Finally, we measured, as in 2018, 2019 and 2020, a decrease of 70% of total phosphorus concentrations in the pit (6.2 m) compared with the observed concentrations before 2017. This is a clear indication that the Phoslock continues to do its job!
