Abstract: | Water is a resource that is essential for all life on Earth. An exponentially growing human population, in addition to unprecedented
industrial and technological development, threaten the availability and quality of this resource. Climate change and ozone
depletion are two major environmental problems facing mankind today. These problems have the potential to further strain currently
available freshwater resources. Recent research has shown that climate change and ozone depletion are linked phenomena and
their interaction exacerbates their impact. Changes in precipitation, surface runoff, solar UV radiation, temperatures, and
evaporation are some of the predicted outcomes of climate change and ozone depletion. They influence the biogeochemical cycles
and aquatic ecosystems in lakes and rivers, and alter the character of natural organic matter (NOM) and, consequently, they
have the potential to affect the quality, quantity and treatability of our water resources. Given these uncertainties, and
the need to mitigate the consequences of climate change and ozone depletion, the issues of changing water quality, quantity
and treatability cannot be ignored by Australian governments and water utilities. |
