ABSTRACT

Water used in the production of a good or service is known as virtual water. Safe drinking water is essential to humans and other life forms even though it provides no calories or organic nutrients. Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack accesses to adequate sanitation. From a biological standpoint, water has many distinct properties that are critical for the proliferation of life. It carries out this role by allowing organic compounds to react in ways that ultimately allow replication. Photosynthetic cells use the sun's energy to split off water's hydrogen from oxygen. Hydrogen is combined with CO2 (absorbed from air or water) to form glucose and release oxygen. The water industry provides drinking water and wastewater services (including sewage treatment) to households and industry. Water supply facilities include water wells, cisterns for rainwater harvesting, water supply networks, and water purification facilities, water tanks, water towers, water pipes including old aqueducts. Atmospheric water generators are in development. Water covers 71% of the Earth’s surface, which is vital for all known forms of life. Only 2.5% of this water is fresh water, and 98.8% of that water is in ice and groundwater. Water can support the growth of many types of microorganisms which can be useful as well as harmful for all livings. This study is based on the finding of the checking of the safety of filter water at the particular area where we studied and tested. The different code no represent as A, B, C and D. The Petri plate was prepared by containing media and the different samples were soaked in antibiotic disc and placed over the media. The study was conducted to check the microbial population, and was done successfully by observing the microbial growth at regular intervals. Our research findings conclude that the water sample B was found safer for drinking as comparison to the other water samples as A, C, D. At the same time we also tested AMAN AQUA Mineral Water and it was found safe for drinking with zero microbial growth.
