Abstract
Formation potential for disinfection by-products (DBPs) is determined in-situ using one or more automated sample extraction and measurement mechanisms. In one embodiment, such an in-situ mechanism is used to take periodic water samples and measure trihalomethane (THM) concentration in near real-time (i.e., less than two hours), using a measurement process based on modified Fujiwara chemistry. During the extraction and measurement process, water samples can be heated according to a specific temperature/time profile in order to artificially accelerate age of the water sample, so as to cause DBPs to form prematurely. A water monitoring network can monitor detected DBP levels and take automated response actions according to predefined computer policies or rules.
