Water is essential to all plant and animal life. Our bodies are 70% water and therefore, a continuous supply of clean and safe water is essential for our existence.
Our planet is covered with water, but 97.5% of it is salt water in oceans and seas. Most of the remaining fresh water is frozen as ice. Only 1% of fresh water on the planet is actually available for human use! We collect water we need from rivers, wells, ponds, rainwater etc.
The total amount of water on our planet has remained the same for billions of years and it moves from one state to another in a natural endless cycle called as the WATER CYCLE (Hydrological Cycle).
The Water Cycle
The sun warms the water in the oceans & lakes causing liquid water to evaporate and form clouds. Over time, water vapor in the atmosphere condenses into clouds and eventually falls as precipitation, rain or snow. When precipitation reaches Earth’s surface, it has a few options: it may evaporate again, flow over the surface, or percolate—sink down—into the ground where we collect it as well water. As water continuously cycles & comes in contact with other matter, it picks up various impurities such as mold, dust, smog, bacteria, smoke, sulfur from industrial smokestacks (acid rain) and carbon dioxide.
Surface Water
Surface water (lakes, rivers, reservoirs) can become contaminated with impurities such as nitrates or animal waste from livestock or fungicides, pesticides and herbicides. From industry it can pick up things like arsenic and detergents.
Ground Water
Ground water is water that has percolated down through different layers of earth like clay, limestone and shale picking up impurities such as radioactivity, sodium, iron, calcium, magnesium and hydrogen sulfide.
It is important to treat the water before consuming it to ensure that it is clean, safe and healthy. Check out Rainfresh products to see how you can enjoy the benefits of clean and safe water.
