WOONSOCKET, R.I. (AP) — Rhode Island environmental officials are investigating whether a waste management company has been illegally dumping tons of out-of-state sludge at the state landfill in Johnston.

Officials told WPRI-TV that Baltimore-based Synagro Technologies allegedly dumped an estimated 390,000 pounds of dried sludge at the Central Landfill during a three-day period last month. Sludge is treated solid waste from sewer treatment plants.

State officials say a Synagro employee called them to report the company was bringing in out-of-state sludge. The landfill does not accept waste from other states.

Synagro has offices in Woonsocket and several other states. Companies that violate illegal dumping laws can face fines by the state Department of Environmental Management.

A Synagro spokeswoman says the company is reviewing the sludge dumping in Johnston.
