A three-year program has been conducted to study the chemistry and biological effects of products arising from the low-level chlorination of natural waters. These studies are related to environmental concerns arising from the discharge of chlorine-treated power plant cooling water. The studies have shown that addition of low levels (2 mg/l) of chlorine to natural waters produces haloforms in concentrations which are orders of magnitude lower than the LC{sub 50}'s measured in a number of fresh ana salt water organisms. Chlorination also produces nonhaloform lipophilic organohalogen products in concentrations much lower than the naloforms, although no evidence was obtained which suggested significant olomagnification of these during chronic exposure of juvenile salmon to chlorinated fresh water. No dramatic effects were noted in organisms chronically exposed to chlorinated waters, but changes in general condition were observed
