Webformation potential is critical to DBP control in water treatment processes. Among currently regulated DBPs are trihalomethanes (THMs, including chloroform, bromoform, dichlorobro-momethane, and dibromochloromethane; TTHM, the sum of the four THMs) formed when chlo-rine or other halogenated disinfectants are used to control pathogens in water ... Webscientific journal5, and on an EPA website6, and 3) the formation of TTHM and HAA5 as cited in a textbook7. I am familiar with the websites, handbook and textbook and although the general impacts cited are true, they are not particularly relevant to the extent of TTHM and HAA5 formation as a function of small increases in temperature. Web(e.g., decomposing plant material). Total trihalomethanes (TTHM – chloroform, bromoform, bromodichloromethane, and dibromochloromethane) and haloacetic acids (HAA5 – monochloro-, dichloro-, trichloro-, monobromo-, dibromo-) are widely occurring classes of DBPs formed during disinfection with chlorine and chloramine. eastwood punch and flare set
