PARIS, June 5 (Reuters) - On a sunny spring day, Dan Angelescu was testing the water quality of Paris' Seine river by the bridge Alexander III - a scenic view for next year's swimming marathon and triathlon Olympic trials. Angelescu has been working for the city since 2017 on its longtime project to make the Seine swimmable. The 2024 Games are a good opportunity to fast-track it in order to host some sporting events in the famous river - as was done at the first Paris Olympics of 1900. Stephane Vidalie, who lives in Neuilly-Plaisance in the east of Paris, was happy to no longer send wastewater into the Marne river, a tributary that joins the Seine just outside Paris. Bastien Coignon, a member of a kayak club in Sevres, west of Paris, said he had been waiting for this.
