CAIRO, Neb. (AP) – A boil order has ended for the central Nebraska town of Cairo. Harmful bacteria had been found in the town’s water supply, but the latest water test showed the water is OK now. The town of about 700 people is just northwest of Grand Island. Village Board chairman Bill Heger said that a test done Monday afternoon “came back clear.” He says it wasn’t E. coli in the system but didn’t know for sure what kind of bacteria it was. The system has been flushed and chlorinated.
