Reducing P by 0.02 grams per litre will cost $100 million

25 August 2012

Droplets readers should, by now, be fully up to speed about why we need to reduce the amounts of nutrients being discharged into our rivers and streams, ending up in our lakes and dams.  Its all about eutrophication and the very negative economic consequences that not paying attention to this problem can have.

Drinking Water App launched in Canada

22 August 2012

An example from Canada’s water quality app.

Some countries are really working hard to keep civil society informed about the quality of water they are exposed to, either in their kitchen tap or when they fall off their paddle ski.  In this age of smartphones and apps, the latest one comes from Canada – the result of a partnership between The Water Chronicles and the Lake Ontario Waterkeepers.  What a great way to keep people in touch, whereever they are!

Hawaiians fed up about sewage dumping into their environment

18 August 2012

Residents of Hawaii’s Maui County have had enough of poorly-treated sewage being dumped into underground wells – and the effects that this bizarre practice are likely to be having on the nearby marine environment.  They have sought a court action to require the responsible authority to have to comply with pollution limits.  Of course the local authority tried to have this dismissed (isn’t it amazing how, around the world, publicly-elected representative bodies try to act so negatively for short-term economic gain, at so much risk to everyone’s future – but, you get what you vote for!).

Deer did not die because of blue-green algae

11 August 2012

Although cyanotoxins have been excluded as a cause of death, experts have still to come up with an answer to what type of toxin, if indeed it was, killed eight deer in Oklahoma earlier this week.  This mystery has some similar echoes to the dog deaths at Sandringham during the past couple of years.

South Africa recognizes need to manage water quality

11 August 2012

At long last a hopefully-definitive statement that may help to draw a line under the continued dumping of poorly-treated wastewater effluents into South African dams.  The long-awaited revision of the National Water Resource Strategy (NWRS-S), a document I have not yet seen but keenly await, apparently observes that:

the [National Planning Committee]  said that the country would have to improve water resource management and promote more efficient municipal, agricultural and industrial usage of water to protect the resource from pollution. Read more »

Commonwealth Games triathlon may need a new lake

Concerns over the risks posed by toxic algal blooms in Strathclyde Loch, Glasgow’s proposed venue for the triathlon swim for the 2014 Commonwealth Games, may cause the organizers to have to look for a less-polluted body of water.  As a first attempt they plan to throw $234000 at the problem.  This artificial lake has a recent history of having to cancel swim events.
