Uane, Not sure of the date range of the TTHM monitoring stats in your attachment or if you are interested in other disinfection byproduct MCL issues such a3 HAAS. Ifjust the last year or so, then what isay below is moot. But if you are going back a ways then: The City of Manistique exceeded the disinfection byproducts MCL for HAAS in 2008 and 2009 and had to past public notice twice. They have since did some treatment plant upgrades, and have returned to full compliance, CHUCK THOMAS, ?.G. DUSPRICT SUPERVISOR DEC-ODWMA U.P. DISTRICT OFFICE 906-228-4514
