A Massachusetts construction company charged with illegally dumping thousands of tons of contaminated fill in Rhode Island during a highway construction project says it has done nothing wrong.

The Rhode Island attorney general's office announced Wednesday that Barletta Heavy Division, Inc., of Canton, is charged with illegal disposal of solid waste, operating a solid waste management facility without a license, and providing a false document to a public official, during the ongoing Route 6/10 interchange project in Providence.

"Barletta’s work on this project did not violate any criminal laws and the charges are baseless, both legally and factually," the company said in a statement. Barletta "is confident that it will prevail and restore its impeccable reputation once the facts are fully and accurately presented in court."
