Thanks to the municipality of Pont-à-Mousson, which entrusted us with the "Grand Bleu," we were able to conduct numerous tests, including treatments for hydrophytes carried out at their nautical base and on their beach. We observed that the treatments were 92% effective at the nautical base and 88% effective on the beach.

Given the satisfactory results, we also conducted tests on cyanobacteria over a 2000 m² surface of the "Grand Bleu." In conclusion, we observed the complete elimination of cyanobacteria, with effectiveness certified by the ARS (Regional Health Agency).

Later, three other municipalities gave us the opportunity to test hydrophyte treatments in their ponds and canals, including the municipality of Mercy Le Bas with its 2000 m² pond "La Crochenière," the 1000 m² pond "La Sandre" in the municipality of Bousse, and finally the Burgundy Canal located in the municipality of Ouges, with an area of 6000 m².

After completing the tests, we received positive feedback with 100% of the hydrophytes eliminated within three weeks at each site.
