Test results of water from Mill Creek this week came back with substantially diminished levels of E. Coli.  That’s after the City did a $40,000 emergency repair of a cracked sewer main on Wright Street that helped wind down a two-year search for the source of a pipe that was dumping E. Coli into the creek.  The latest test showed 387 E. Coli organisms per 100 milliliters of water, way down from the over 2,400 over the last two years, and out of the federal designation of an acute level.  City officials will do more testing, with the current reading still over the federal definition of a chronic level of E. Coli, which is 126.  Dropping to zero is not realistic as Mill Creek has several sources of E. Coli, including wild animals.  Also still unknown:  the origin of the pipe itself.
