This pilot project reveals surprising information which now allows us to make these three main observations:<\/p>\n<ul>\n<li>the water is generally adequate for swimming in the summer months;<\/li>\n<li>from September, there is persistent pollution and intensive municipal discharges upstream;<\/li>\n<li>contamination of water by <em>coli<\/em> is mainly of human and non-agricultural origin.<\/li>\n<\/ul>\n<p>The general director of Fondation Rivi\u00e8res, Mr. Andr\u00e9 B\u00e9langer, is amazed by the results of the study: \u201cInitially, we wanted to know, among other things, whether the ColiMinder rapid detection system was effective in ensuring the safety of swimmers at the swimming pool. relaxation L\u00e9o-Jacques, in the event that the City makes this place accessible for swimming. Today we learn not only that the effectiveness has been demonstrated, but that the water in the river is of much better quality in summer than we had anticipated. In the fall, however, it\u2019s a completely different picture unfortunately.\u201d Indeed, from the month of September, with heavier rains, analyzes demonstrated persistent pollution and intensive municipal discharges of wastewater upstream during periods of rain.<\/p>\n<p>The human origin of contamination by <em>E.coli<\/em> also provoked strong reactions: \u201cFor years, agricultural activities have been identified as the main cause of poor water quality in the L&#039;Assomption River, but this is probably not the case! This new portrait will make it possible to guide future actions in a much more optimal manner by allowing the stakeholders concerned to better target the real priorities: upstream wastewater spills.<span style=\"text-decoration: line-through;\">.<\/span> This is major news! \u00bb<em>, <\/em>to add M<em>. <\/em>B\u00e9langer.<\/p>\n<p>The project was all the more beneficial as it made it possible to optimize the operation of the Water Treatment Center and to quickly adjust operations during unexpected periods of contamination. On September 17, the <em>ColiMinder<\/em> has in fact detected a peak of contamination which extended from 11:00 a.m. to 5:00 p.m. While there should be a strong correlation between turbidity and contamination, the Treatment Center&#039;s turbidimeter did not reflect this. Thanks to <em>ColiMinder<\/em>, it was possible to detect a spill occurring more than 10 kilometers upstream and adjust the treatment more quickly.<\/p>\n<p>The results of this collaboration are now leading the City of L&#039;Assomption to consider the follow-up to this study: \u201cWe are delighted with the work of Fondation Rivi\u00e8res and their professionalism. In its recommendations, the Foundation offers us very relevant actions to implement for better sanitation of river water. As always, we are ready to take concrete actions in collaboration with the various stakeholders in the area concerned about the quality of our waterways\u201d<em>, <\/em>concluded the mayor of L\u2019Assomption, Mr. S\u00e9bastien Nadeau.<\/p>\n<p><strong>The project <\/strong><\/p>\n<p>The project consisted of performing analyzes automatically every two hours. These were carried out with a device <em>ColiMinder<\/em> deployed in the factory which makes it possible to detect in 15 minutes the presence and quantity of <em>E.coli<\/em> in water. The results were transmitted in real time to the operators. The project ran from August to December 2020 and pursued three objectives:<\/p>\n<ol>\n<li>Validate whether the measures provided by the ColiMinder device can ensure the safety of citizens at the L\u00e9o-Jacques Park relaxation area in the event of occasional contamination, in the context where the City is evaluating the possibility of making the place accessible for swimming;<\/li>\n<li>Validate the relevance for the Water Treatment Center to use a rapid analysis tool to monitor contamination in real time;<\/li>\n<li>Identify sources of contamination that may present risks to the City&#039;s drinking water intake.<\/li>\n<\/ol>\n<p><strong>Documents to consult<\/strong><\/p>\n<p><a href=\"https:\/\/drive.google.com\/file\/d\/1BenuZbwzUnVSKhPAHXufvAvLAvhXm8UN\/view?usp=sharing\" target=\"_blank\" rel=\"noopener\">Full report<\/a><\/p>\n<p style=\"text-align: center;\">- 30 -<\/p>\n<p><strong>For informations :<\/strong><\/p>\n<p><strong>Genevi\u00e8ve Tardy<\/strong><br \/>\nCommunications Manager<br \/>\n514 424-3556<br \/>\n<a href=\"mailto:communications@fondationrivieres.org\">communications@fondationrivieres.org<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Press release - Fondation Rivi\u00e8res and the Ville de L'Assomption have released the results of continuous monitoring of water quality in the Rivi\u00e8re L'Assomption at the Centre de traitement Jean-Perreault intake and at the L\u00e9o-Jacques Park recreation area in L'Assomption.
