  (144) Total chlorine--The sum of both the free available and combined chlorine.

  (145) Toxic--A substance that has an adverse physiological effect on human beings or other living organisms.

  (146) Turbidity--Cloudy condition of water due to the presence of fine particulate materials in suspension that interferes with the passage of light.
