harvest their bounty
Water is abundant on our great blue earth, but less than 2% of our water is drinkable. With the world population growing every instant, it's possible that this commodity will become ever more sought after in the future. Read on to learn why freshwater is so rare, and what makes a mineral rich water so different from your average bottle of Poland Spring.
The Water Table: This is where water emerges from the surface of the earth. It's here that streams and fresh-running water emerge, and allow us to harvest their bounty.
Groundwater: When it rains, water that sinks into the ground is called, rather obviously, groundwater. Plant roots and rocks in the ground filter water as it moves deeper and deeper, until it pools in underground aquifers.
Porous Rock: This rock allows water to seep through it. Limestone is an example of this kind of rock, which can be seen in many caves around the world.www.doublex.com.hk/products.html
Non-porous Rock: Bedrock is one of the more common types of non-porous rock. It takes a lot of time for water to filter through this kind of rock. On its way deeper into the ground, water absorbs some of the minerals from the earth and trickles into pools called:
Artesian Aquifers: These aquifers are much deeper than shallow ones, and it takes water a much longer time to filter to these depths. Part of the reason for this is the thickness and hardness of non-porous rock, through which groundwater has to pass until it comes to rest. Artesian water can be pumped from the earth and bottled immediately without purification.
Unconfined Aquifer: This kind of aquifer is closer to the water table than an artesian aquifer. When these aquifers are pumped dry, sinkholes can result, www.sem-link.com/doc/woven-label-an-product-labeling.wps
leading to collapse of the earth into what used to be an unconfined aquifer full of water. This is where most of our municipal water comes from after undergoing treatment by:Reverse Osmosis: This process purifies water of nitrates from runoff, sewage and fertilizers that infect it. RO, as it is often abbreviated, is also useful in purifying saltwater of its salt and making it drinkable.
