<strong>Chlorine</strong> <strong>Decay</strong>, <strong>Water</strong> <strong>Age</strong>, <strong>and</strong> <strong>THMs</strong> – <strong>OH</strong> <strong>MY</strong>Residual <strong>Decay</strong> Models• First order reactionCtCoekt• Calculate decay coefficient (k) using water age from zero days to xdays• Two day intervals• Can use shorter or longer intervals as needed• k values appear to be site specific• Temperature dependence of k - 2 fold change for each 10 o C changein temperature (adjust k accordingly)5
