Paul Oates, a spokesman for the Connecticut Department of Labor, confirmed that the department on Thursday issued stop-work orders to the Massachusetts-based Callahan & Montalto Site Construction and to the Texas-based Malden Steel. These two companies have been among the subcontractors working on the $54 million renovation of the water treatment plant, located off Poquonnock Road across from South Road. Groton Utilities hired R.H. White Construction Co., which it said was the low bidder, as the general contractor.
