A Wearable Lifesaver

Spring is here and before you know it the beaches and pools will be open. Water safety for everyone should go without saying. Here is a device that is new on the market or maybe it is the first time I have become aware of it. The Kingii Wearable is for everyone who loves the water.

Kingii is the new wristband for everyone who spends time in and around the water. If you need help to stay afloat, pull the lever, and an inflation bag will take you to the surface. It is a tiny life-preserver, light weight, and can be worn in and around water.

It is reliable and reuseable. After the bag is deployed replace the CO2 cartridge and it will be good to go.

It is not to replace a life vest , but to provide additional buoyancy. A new way to go out and be safe on the water.

World Water Day, was yesterday.

Did anybody notice that World Water day was yesterday, Wednesday, March 22. This year’s theme was /is Waste Water.

 

5 thoughts on waste water from World Water Day.

Over 80% of all waste water is not used again. According to the U.N. recycling waste water could help ease water shortages. With treatment and technology this used water can become new again.

Modern urban wastewater treatment plant.

70% of all water withdrawals are from agriculture. Irrigation systems are responsible for the most water withdrawls world-wide. As the use of technology in farming drops, there is an increase in the use of this raw resource. This is a problem because in underdeveloped countries there can be a more problematic access to water, and the amount of water needed for agriculture can go as high as 90% of what is available.

Leaking taps lose up to 5,500 liters of water a year.

 

Less than 3% of the world’s water is drinkable…and most of that is trapped as ice in the Arctic and Antarctic.

Over 20% of all fresh water fish species are in danger or extinct. Our use of freshwater has a significant impact on our fish populations. it is just not about us.

Planet Reconciliation/ Blue Ecology

Water is moving through the global water cycle more quickly and more disruptively thanks to the warming of the planet’s atmosphere. Extreme weather events are becoming the norm. Human activities are magnifying the impact of these events. We have arrived at an intersection , which path will we take.

We can look at water and water sheds through a narrow technical lens, but the risks of error great. Perhaps we can look at the situation through a whole systems approach…even re-visiting our relationship with nature.

Let us consider Blue Ecology which is defined as the interweaving of western science and traditional First Nations teaching and local knowledge. Blue Ecology has 5 guiding principles and aligns with the whole system, water balance approach– Spirit, Harmony, Respect, Unity, and Balance. To make the right choices we must understand how and where the rhythms of water are changing. then we apply ecosystem based understanding to adapt our practices to suit a changing climate.

 

 

Atmospheric rivers have recently been identified as a narrow corridor of concentrated water vapor aloft. These can be great rivers, perhaps the best known is the “pineapple express”. This river in the air periodically crosses the Pacific from Hawaii dropping rains on the west coast of North America..sometimes the water is much-needed , sometimes it can cause serious flooding devastating communities in its path. With the warming of the atmosphere the more moisture can be held aloft. We need to consider stabilizing the Earth’s atmosphere or face the likelihood of more flooding and serious economic damage. The idea of sustainability and adaptive resilience become a moving target.

 

Success depends on embracing a water first approach. Water is a core human value upon which we can build a cross cultural climate change strategy. Indigenous societies believe that water is a living entity, a sacred centre from which all other activities radiate. The Blue Ecology frame provides a holistic cultural context to enhance Western sciences knowledge of the water cycle for the benefit of hydrologists and water managers.

 

The Sliver Carp is on the move.

The invasive silver carp famous for leaping out of the water to the peril of boaters has been caught on the St. Croix river bordering Minnesota and Wisconsin. These are some of the most pristine water to be found in America, so the find is disappointing but not unexpected.

A commercial fisherman caught the 13 lb fish close to where the St. Croix meets the Mississippi. 2 other silver carp were caught in the area in 2014, as well as another invasive species the big-headed carp.

The silver carp, big head carp , and other invasive species escaped into the Mississippi in the 70″s and have been working their way upstream since. The danger is that these are a large aggressive fish that can take over an ecosystem at the loss of the native species.

Where these fish have been caught are popular areas where several species of fish overwinter. It is not thought that a breeding population has been established as yet. it is possible that these fish will move back into the Mississippi river as spring temps warm up the river. Once the ice thaws a more in-depth search will be conducted to try to establish the true extent of the issue near Prescott, Wisconsin.

Various techniques have been used to try to stop the spread of these invasive species like closing dams in their path, fences, even installing acoustic speakers.

 

 

The Cassava Bag

Over time we have done a few blogs looking at the amount of plastic we have floating around the oceans of the world. There are several groups coming up with some great ideas as to how we can help out the oceans by clearing out the churn or debris. Here is a different take on plastic for you to consider…the cassava bag…but first what is cassava?

Kevin Kumala has created a bag made out of cassava starch, it is 100% biodegradable and even edible. Watch as Kevin tears off a piece of the bag, dissolves it in lukewarm water and the drinks it. Absolutely brilliant!

 

 

Why are we still using petroleum products to make our bags?

Pink tap water…Yikes!

On Monday residents of Onoway, Alberta complained to the town office when the water from their taps was running pink. In a statement the Mayor Dale Crasnow said there was no public health risk, but better communication could have been helpful.

The Mayor said the pink water is a normal side effect of a common water treatment chemical..potassium permanganate. Commonly used to remove iron and hydrogen sulphide from water, it got into the town’s reservoir when a valve malfunctioned during normal line flushing and filter back washing

The reservoir was drained, but some of the chemical managed to make it into the distribution system. The chemical can cause skin irritation, but there were no reports of this effect.

The townspeople were a bit miffed about not being informed in a timely manner. I can imagine that this valve malfunction was quite possibly caused by human error. Someone is embarrassed, but no harm done.

 

 

 

 

World’s First Ship Tunnel

Norway has given the go ahead to the Stad Ship Tunnel, the world’s first full scale ship tunnel, bypassing one of the most dangerous areas for vessels along the Norwegian coast. 

The tunnel will be blasted through 1.7 kilometres of rock at the narrowest point of the Stad Peninsula. The route is actually not expected to save that much time, but is intended to allow for a more safe navigation of the Stadhavet Sea, where the North and Norwegian Seas meet. This area is considered to be one of the most exposed and dangerous areas for vessels to sail along the Norwegian Coast. There is a dangerous combination of wind, currents, waves, and more than 100 storms per year. Since the end of WWII some 33 people have lost their lives in this area. 

The Norwegian Government has approved the full funding of the project of 2.7 billion NOK, lasting until 2029. Construction will involve conventional blasting using underground drilling rigs and pallet rigs, used to remove approx 3million cubic meters of solid rock. When completed the tunnel will be 1.7 k long, 37 m high, and 26.5 meters wide. 

The Stad Ship Tunnel will serve as a safe route for ships, but also should also be a popular tourist attraction with potential overhead viewing areas open to the public.
