Today I had hoped to post on wastewater treatment in Dunedin, however the information available online was rather lacking as to what actually was happening with the $100 million upgrade to the Tahuna Wastewater Treatment Plant. When I called the DCC, a nice man called Guy told me there was no updated information available and to get this I would have to talk to the Wastewater Team who are currently all away enjoying the long weekend!
So I’ll put that on hold till next time, when hopefully I can provide those of you who do not know with the details as to what happens once your water disappears down the plug hole. And as for today? Im going to share with you some fascinating facts I have found about water:
1. Water can dissolve more substances than any other liquid including sulphuric acid.*
2. Plumbosolvency refers to the ability of water to dissolve heavy metals.
3. More than 25% of bottled water comes from a municipal water supply, the same place that tap water comes from.*
4. No substance other than water is naturally found on earth in the three forms: solid, liquid and gas.
5. Because water in the earth comes from a closed system, it is recycled over thousands of years. The water the dinosaurs drank millions of years ago is the same water that comes out of our tap today.
6. The Antarctic Ice sheet is the largest mass of ice on earth. It covers an area of almost 14 million square km and contains 30 million cubic km of ice. **
7. Dihydrogen monoxide is the scientific name for water, check out http://www.dhmo.org/ for a laugh.
8. Half of the world’s wetlands, our natural water filters have been lost since 1900.*** (More on wetlands to come on The Water Watch)
9. Irrigation increases yields of most crops by 100 to 400%, and irrigated agriculture currently contributes to 40 percent of the world’s food production.***
10. And finally, on a slightly different note, I was interested to find out that Hippopotamuses are only territorial in water, where a bull presides over a small stretch of river. **
I hope you learnt something new and interesting today, tune in next time for the rest of the pollution series.
