Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

amounts of water consumed in the brewing process as well as washing and sterilizing procedures. It is estimated that between 4 and 7 L of water is required to produce 1 L of beer. Beer is the fifth more popular drink in the world so to meet this demand; large quantities of water are required. Water chemistry has an effect on the brewing efficiency as well as the taste‚ so water from water authorities must be treated in order to produce water which is acceptable for brewing. Demand for water has become

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such

Water Waves By Anna Introduction Water waves have been around for years; learning about water waves can help you understand the outside world. Water waves can be used in many ways‚ but they can also be harmful‚ too. When were they discovered? Water waves have been around since the creation of the earth‚ but Isaac Newton came up with a theory; after studying waves in about 1687. What is the biggest wave? In 1958 the biggest tsunami wave was recorded. How much harm can water waves really

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker

Water and Life on Mars Mars perhaps first caught public interest in the late 1870s‚ when Italian astronomer Giovanni Schiaparelli reported using a telescope to observe canali‚ or channels‚ on Mars. By the turn of the century‚ popular songs told of sending messages between Earth and Mars by means of huge signal mirrors. On a darker side‚ H.G. Wells’ 1898 novel The War of the Worlds portrayed an invasion of Earth by technologically superior Martians desperate for water. (1) In the early 1900s
