Nitida Cellars to showcase BioHaven floating islands

6 August 2012

Nitida Cellars, a boutique winery in the Durbanville Hills outside Cape Town, will be installing a small fleet of BioHaven floating islands in the dam alongside their Cassia Restaurant.  These will not only improve the water quality but will provide a floating showpiece.  Droplets will keep readers posted on this initiative from the day that the islands are launched!

Video about blue-green algae released

5 August 2012

Wisconsin’s Department of Natural Resources has released a very useful video about blue-green algae, why they cause problems and the threats they pose to human and animal health.

This is a must-view video for anyone, in any country, wanting to learn more about this important issue.


Smelly water is / is not safe for consumption?

5 August 2012

I have initiated this debate before:  although tastes and odours produced by blue-green algae are not, in themselves, toxic, is it safe to conclude that the water is safe to drink.  Personally I don’t think so, unless appropriate testing has been undertaken to exclude the presence of the other nasties produced by these algae.

Here are a couple of examples from todays’ press: Read more »

Stormwater-borne pollution gets capped

Western Washington putting a LID on polluted runoff

New stormwater permits ramp up protections

for Western Washington waters

OLYMPIA – The state Department of Ecology (Ecology) today released new, updated municipal stormwater permits that will require the most populated areas of Western Washington to use low impact development (LID), and to begin monitoring improvements to water quality.

LID employs techniques using vegetation and soil to mimic how Mother Nature naturally manages rainwater and keeps it from running over hard surfaces and collecting pollution along the away.

During rainstorms and snowmelt, stormwater runoff carries toxic chemicals and bacteria into bays, lakes and rivers and Puget Sound. Stormwater runoff pollution from urban areas is the greatest threat to Washington’s waters. Read more »

Blue, blue, my lake is blue

1 August 2012

I was not aware that dyes were still being used to combat algal blooms but $30 000.00 has just been spent changing the colour of Lake Delton in Wisconsin.  The report plays this as trying to make the lake look more attractive but I assume it is an attempt to reduce light penetration into the water and so try to reduce algal growth.  The money could have been better spent!  The River Alliance of Wisconsin concurs with my view on such desperation measures.

Child dies from waterborne disease in Oklahoma

1 August 2012

Sadly a child has succumbed to ingesting the amoebic protist Naegleria fowleri in Oklahoma’s Red River.  The organism is ubiquitous but can develop large numbers in warm stagnant water, much like the cause of flesh-eating fasciitis.  Warm and stagnant water is also an ideal environment for toxic algae, as noted in the same report: Read more »
