The total mutagenic activity of chemical pollution of the water 
taken from the Volga water reservoir was investigated after its 
treatment with chlorine and ozone. The toxicity of the water was 
absent after its ozone treatment. Mutagens were found to form 
after water chlorination. Their levels can be reduced by 
subsequent treatment with ozone in a dose of 0.5 mg/l.
