WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above

Topic 6 Water Quality and Water Management What determines water quality? Drinking water should be colorless‚ odorless and flavorless; this means that there are no organisms and sediments in the water‚ but it does not mean that if your drinking water look‚ smells and taste clean‚ that does not mean that there is nothing else it. Water also contains dissolved solids: •Sulfur •Calcium •Magnesium If water contains a lot of dissolved calcium and magnesium it is called hard water

determine how an excess amount of liquid‚ which was water‚ Gatorade and wine in this case‚ along with an excess amount of solute‚ which was the 7g NaCl pill‚ would affect the kidneys and the osmolarity of urine. Measurements of urine volume‚ specific gravity and chloride concentrations were recorded in order to investigate this. Our hypothesis stated that the volume of urine would increase for all groups other than the group drinking 80 ml of water along with taking a 7g. This portion of the hypothesis

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper

Wastewater Wastewater is any water that has been adversely affected in quality by anthropogenic influence. It comprises liquid waste discharged by domestic residences‚ commercial properties‚ industry‚ and/or agriculture and can encompass a wide range of potential contaminants and concentrations. In the most common usage‚ it refers to the municipal wastewater that contains a broad spectrum of contaminants resulting from the mixing of wastewaters from different sources. Sewage is correctly the

How can water generate Electricity? There are two primary methods for generating electricity from water. One method uses the energy potential of trapped water in dams in a more sophisticated version of the water wheel‚ and the other method of generating electricity is to capture energy from ocean waves. Electricity generated from water is entirely renewable‚ sinccete water is an abundant natural resource First method:When a dam is used to generate energy‚ tunnels are installed in the dam when

Business Opportunity Originated‚ Screened and Confirmed Viable: Water desalination is the removal of salts and dissolved solids from saline water (brackish or seawater)‚ also known as Desalting or Desalinization. In addition to the removal of minerals‚ the process removes most biological or organic chemical compounds. Desalination systems have been used to supply potable water for coastal communities and urban centers in more than 40 countries. Desalination plants operate in almost all of the world’s

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers
