A broken sewer line on Dock Street in Lansford threatens this year's 15th annual ZooStock, which is scheduled for Labor Day weekend. The ZooStock in the largest fundraising event for the annual telethon of the American Cancer Society, held in April. Lansford Borough Council agreed to make emergency repairs to the line, but said ZooStock can only occur if the line is repaired by then. The council said it has concerns about liability issues if someone should fall into openings made to find the broken line. ZooStock is held on the grounds of the Sports Zoo in Lansford. The broken pipe is both adjacent to, and on, the Sports Zoo property.
