Large piles of concrete mixed with dirt, rebar and assorted trash await removal after being dumped just yards away from the edge of the San Antonio River. Karnes County Road and Bridge Administrator Jeff Wiatrek said he was not aware that an unacceptable amount of trash was mixed in with materials from a hospital demolition site that he planned to use as part of a project to stabilize the support structures beneath the Wofford’s Crossing bridge on County Road 326 at a location about 3.5 miles west of Runge until work was underway. County officials have declared the situation a “public calamity” and hired a private contractor to move the rubble away from the river banks. What to do with the 720 tons of material lined up along the edge of County Road 326, however, has yet to be decided.
