Municipal water systems, well, tap waters which the public use for their drinking-use (cooking, tooth brushing, cleaning and so on) requirements and also stream, river, and lake waters which are refined for the same purposes are defined as drinkable water. The water which are used for drinking and various purposes and have close relations with the human health and which are called as drinking-use water in short are called as “Alimentation Water”.

To prevent the water-borne epidemics which were present in the past and “continue to be present nowadays” and the diseases and deaths due to those epidemics and to supply “healthy-clean” water to people, water are processed from purification systems. After passing through various processes in purification systems and making the water suitable for the health conditions, it is sent to the delivery systems.

“Healthy water is the one which is colorless, odorless, and clear and which was cleaned from microbiological and chemical contaminants that can damage the health and also which includes the necessary minerals for the health in suitable and right amount.”
The suitability of the water, which is given to the delivery systems to deliver to consumers, for certain standards and conditions is almost complete; however, the desired quality of water is corrupted during the trip in the delivery units due to various reasons. The most important factor in the decrease of water quality is the increase of microorganism number in the water. Moreover, another factor important in the water quality is the chemical ingredient. During the purification of water, including the disinfectants used to combat the microorganisms, various chemicals mixing with water from outside unwilled decrease the chemical quality of water. In addition to all, another determiner parameter to determine the water quality is the physical features.
*Analysis for Drinking and Use Water is done in our laboratory.
The conditions which the drinking and use water should obey (Appendix-1 a,b) are stated and the indicator parameters are reported in Appendix-1 c in “The Regulation Concerning Water Intended for Human Consumption (Date of Official Gazette: 17.02.2005, Number of Official Gazette: 25730)” published by the Ministry of Health.
