Tom McNally, the assistant superintendent of the Water Pollution Control Authority Treatment Facility, is out on administrative leave pending an investigation.
Mayor Ronald McDaniel says McNally has been out for two to three weeks.
The town's attorneys are investigating a personnel matter, McDaniel said. He had no sense of when the investigation might be completed.
"Not soon enough," he said.
Mike Didato, McNally's immediate supervisor, could not be reached for comment.
