Conestoga-Rovers & Associates (CRA) is a group of companies that provides engineering, environmental consulting, construction, and information technology (IT) services.

Their U.S. headquarters resides in Niagara Falls, New York where the company's seminal project, the Love Canal, took place.

The Love Canal Landfill, one of the pinnacle environmental projects in US history, was an open trench that was filled with hazardous chlorinated organic wastes from a chemical plant in Niagara Falls, NY, during the 1940s and 1950s.

A residential area and elementary school were constructed immediately adjacent to the former three-block landfill in the 1960s, resulting in an environmental disaster that eventually prompted the initiation of the Superfund Legislation in the United States.

CRA developed an understanding of the hydrogeology and chemical presence, designed a remedial plan, and provided construction oversight for its implementation.
