The effect of reclaimed potable water on cardiac rhythms of 190 noninbred white male rats was investigated in a 6-month experiment. The water contained 25.0 to 100.0 mg/l sodium and/or 2.5 to 10.0 mg/l potassium. The water containing 100 mg/l sodium and 10 mg/l potassium caused changes in both compartments of the autonomic nervous system controlling cardiac rhythms. The water containing 75.0 and 50.0 mg/l sodium and 7.5 and 5.0 mg/l potassium produced insignificant changes in cardiac rhythms. The water containing lower concentrations of sodium (25.0 mg/l) and potassium (2.5 mg/l) had no effect.
