Part of M3 Engineering’s mission is to make a difference in our environment.  That’s why we participate in the Open Space Council’s Operation Clean Stream.  Operation Clean Stream is one of the Country’s largest and longest running river restoration projects and takes place in St. Louis on the Meramec River and its tributaries, working to undo damage caused throughout the year by flooding, careless littering and the unlawful dumping of trash. This year’s event was a success, with almost 2000 volunteers cleaning up nearly 500 miles of local rivers.  Marc Eshelman and Sean Martin helped to clean up the Meramec River at George Winter Park.
