Abstract |
Humic and fulvic substances in natural waters were first suggested as trihalomethane precursors in 1984. After this discovery, research in the field assumed one of two directions. First, some investigators began looking at the nonvolatile organic chlorine fraction of chlorinated natural organics. Second, other researchers attempted to find ways of reducing trihalomethane (THM) concentrations in treated waters. Approaches have included reducing precusor concentrations, removing THMs after formation, and changing disinfectants. With regard to this last approach, work showed that the addition of ammonia drastically reduced THM production by the chlorination process. This observation regenerated interest in monochloramine as an alternative to chlorine in water treatment. (Copyright (c) 1985 by Lewis Publishers, Inc.) |
