<strong>Chlorine</strong> <strong>Decay</strong>, <strong>Water</strong> <strong>Age</strong>, <strong>and</strong> <strong>THMs</strong> – <strong>OH</strong> <strong>MY</strong>Temperature/pH Effects• Formation reaction changes 2 fold each 10 o C change• Lower temp slows reaction rate• Higher temp speeds reaction rate• Summer conditions significantly increase THM levels• Affects NOM concentrations <strong>and</strong> precursor material• Lower temp reduces <strong>org</strong>anic decay <strong>and</strong> NOM in source water• Higher temp increases NOM formation from <strong>org</strong>anic decay31
