Drinking water taste
and odour continues to be
a major concern
to public, industry and science. As a primary gauge of drinking water quality,
taste and odour has a major effect on human behaviour, and can seriously
undermine consumer confidence in public supplies. Taste and odour causes major
problems for water suppliers with public image and accountability for, who face
rising treatment costs in order to deliver safe, acceptable drinking water.
However despite considerable research, many taste and odour issues remain
unresolved.
Taste and odours due to
biological growth (e.g. bacteria, algae) often remain untraced, particularly in
large, fractionated and multi-use basins and water bodies with considerable
spatial and biological complexity such as the North American Great Lakes. Little
is known about the physiological ecology of these compounds and their roles in
aquatic food webs, their environmental triggers, and the conditions that favour
outbreaks of odour-causing species.
