Prosecutors in the French city of Rouen have begun a criminal investigation into Solvalor, a company that is part of the Artesa group and focuses on cleaning up polluted soil. The investigation centers on possible environmental violations at one of Solvalor's sites along the Seine River, which is located in the communes of Amfreville-la-Mivoie and Sotteville-les-Rouen. According to the local news outlet Le Poulpe, the inquiry is looking into potential illegal activities at the site, such as mishandling harmful substances and not following environmental rules. This is the first time Solvalor has faced a criminal investigation, although it has previously been penalized by the Seine-Maritime prefecture for administrative violations. The investigation is still in progress, and no official charges have been brought yet. Prosecutors have not provided specific details about the case, but it is known that they are reviewing the company's operations and the possible effects on the environment. Solvalor has not yet responded to the investigation, but it is expected to issue a statement in the near future. The case highlights growing concerns about environmental compliance in industrial operations and the potential legal consequences for companies that fail to meet environmental standards. The outcome of the investigation could have implications for the company's future and its relationship with local authorities.
