Analysis of physical indicators of some water samples from Romania

In this paper, are monitored following indicators physics of water in Eforie Nord, Herastrau Mogosoaia Moeciu, Bordei: turbidity, pH, oxygen, conductivity, such variation is made and physical indicators of temperature. To measure this quality indicator of water, we used: turbidimetru portable microprocessor type HI 93 703, oxigenometru portable microprocessor type HI 9146, HI 9214 pH meter type.
Natural water quality is determined, in general, all mineral and organic substances, dissolved gases, particulate matter and living organisms present. Conductivity of water is one of the most used indicators to assess the degree of mineralization, water conductivity measurements allow determination of total dissolved salts in water.The concentration of hydrogen ions in water (pH), is an important factor determining the reactivity of water capacity, its aggressiveness, ability to provide water for development of various media organizations. Turbidity is due to solid particles or in the form of colloidal suspensions. It is therefore very important to monitor physical indicators of water.
