Water Quality Statistical Computation Analysis

Abstract

Water is a chemical substance with the chemical formula H 2 O. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, 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 70.9% of the Earth's surface and is vital for all known forms of life. A very small amount of the Earth & water is contained within biological bodies and manufactured products. Water plays an important role in the world economy, as it functions as a solvent for a wide variety of
chemical substances and facilitates industrial cooling and transportation.Water quality is the physical, chemical and biological characteristics of water. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. It is most frequently used by reference to a set of standards against which compliance can be assessed.
