Three C's of overcoming contaminants: Collaboration, cash and change
21 September 2022HydroTerra is passionate about the environment and our core skill is monitoring facilities and their emissions to the environment. The drivers for what we measure are usually related to achieving compliance. We have a strong regulatory framework in Australia, which works well. But, what I’m a bit worried about – well, getting very worried about – is that compliance-based management is only as good as the rules we have in place, and the rules seem to be lagging.
The spectre of emerging contaminants (ones that we don’t have rules for yet), and the growing evidence that these contaminants have a negative effect on the environment and humans, is extremely concerning. The USEPA stated way back in 2002 that contaminants of emerging concern may be impacting aquatic life.1 While in more recent studies, researchers have concluded that “Substantial evidence supports a negative association between exposure to phthalates, PCBs, PBDEs, pyrethroids, organochloride pesticides and male fertility and fecundity in humans. That is bad news!” 2
It’s comforting to see our regulators (Department of Environment, Water, Land and Planning and the Environment Protection Authority) and researchers (such as the University of Melbourne’s Centre for Anthropogenic Pollution Impact and Management) taking steps to gain a better understanding of the ecosystem level impacts of emerging contaminants, however even they concede we need to know more. And, as quickly as our understanding of this issue grows, so too must our regulations adapt.
I believe industry and researchers have a big role to play in helping the regulators develop the right rules, so we measure the right things and can manage to appropriate settings. I have no doubt we can do it, after all we made the contaminants in the first place!
In this month’s newsletter we look deeper into the world of “forever chemicals” and into some other effects that humans are having on our natural environment.
