CHAPTER ONE
1.0 INTRODUCTION
Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on earth with its solid state ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water covers 71% of the earth’s surfaces and is vital for all known forms of life. On earth’s surface 96.5%of the planet’s water is found in oceans, 1.7% in ground water, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and o.oo1% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air) and precipitation. Only 2.5% of the earths water ground water. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the earth’s fresh water (0.003%) is contained within biological bodies and manufacture products. Water on earth moves continually through the water cycle of evaporation and transportation (evapotranspiration) condensation, precipitation, run off, usually reaching the sea.
