You'll find, however, exceptions, like the Netherlands, aspects of Germany, Austria and Switzerland7, where no residual is used. This is often driven by disinfection Gains getting outweighed by challenges associated with perhaps carcinogenic DBPs, which are of developing worry with expanding detection/identification6,eight.
