Greenwashing Blue Mountains Water Quality

This water reservoir tank is one of two on the ridgetop at Narrow Neck Road, Katoomba (Central Blue Mountains, New South Wales) which supplies drinking water to the immediate and surrounding residents of Katoomba.

Previously, in May 2013 we took a photo of both tanks showing the white chlorine salt efflorescence stains and we published an article later in August that year.  Why then should someone wish to paint over the stains with green paint?  Do they think it will make the water cleaner and more appealing to be drunk?

In our previous article on this topic we asked:  “Are we to now expect fresh green paint over the chlorine salt efflorescent tanks to hide the problem?” It seems Sydney Water has done just that.  Who else would spend their own money to paint over a government water tank? Why is it that Sydney Water’s water quality analysis measured at the upstream Cascade Reservoir and not from these tanks before it flows to residents?

This is the analysis:

This is the same tank previously in May 2013:

    I find Sydney Water’s failure to do and publish water quality measurements downstream from the tanks unacceptable, as even if it did overlook the fact that the water quality from the tank can differ from that in the upstream Cascade Reservoir because the chlorine salts from the disinfectant as well as other impurities found upstream can accumulate in the tanks, then the efflorescence stains on the tanks should have alerted it to it.
