  • Total trihalomethanes (TTHMs), a byproduct of the chlorination process, can also negatively impact reproductive systems and cause cancer.

  • While disinfectants are effective in controlling many harmful microorganisms, they react with organic and inorganic matter in water to form DBPs. 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.

  • Reported analytical data for Total trihalomethanes (TTHM) exceeded 70% of the calculated daily average water quality-based effluent limitation for human health protection (using consumption of fish tissue criteria), but was less than 85% of the calculated daily average water quality-based effluent limitation for human health protection (using consumption of fish tissue criteria).
