Uses of water: 1. For drinking and for life processes. On an average‚ a man consumes about 60‚000 to 80‚000 litres of water in his lifetime. The body of an adult contains nearly 40 to 50 litres of water at any given time and water constitutes about 66% of the average body make up. Aqueous solutions fill the cells in the body. Nutrients‚ oxygen‚ and metabolic waste products are transported by blood‚ which is mostly water. Digested food is absorbed in the form of an aqueous solution. In plants too

the current water shortage on Oahu. For the purpose of this paper‚ our group has chosen to discuss what we believe to be the top three most feasible technological solutions. In order of current usability they are; 1. Water recycling 2. Desalination 3. OTEC (Ocean Thermal Energy Conversion) Water Recycling Water recycling here on Oahu is an important part of ensuring a sustainable water supply for future generations. Through the natural water cycle‚ the earth has recycled and reused water for millions

The Importance of Rewriting Storm Water Regulations Danielle Nielsen Goochland High School Abstract This paper observes the negative and harmful effects of water pollution and storm water runoff on the environment and the surrounding community. The most common form of water pollution is sediment runoff. It then goes on to explain the research and effectiveness of Best Management Practices (BMPs) and their positive effects. BMPs are conservation practices that can preserve or improve
