Workers enter the Wabash Tunnel at an access point near West Broad and Berwick streets Friday morning. The men refused to identify themselves and ordered the media to leave, saying, "Get out of here," with one worker actually running away from view of the camera. Borough Manager Kevin Steigerwalt said the workers are from A One Service of Shenandoah and are in town to begin testing on the wild cat sewers located along the Wabash Creek. The firm was hired by borough council at their February meeting.
