Edward F. Schmitt, vice-president of Gibson-Thomas Engineering, addressed a packed house Monday night at the Bradys Bend Township building. Schmitt, whose engineering firm works with Bradys Bend Township Water and Sewer Authority, attended the meeting at the request of the water authority's board to help explain the situation with the townships water system leading to the month-long water boil advisory affecting hundreds of customers. After a series of heated exchanges, residents asked Schmitt to leave the meeting.
