I heard that the teacher talks about lectures in class. Then my eyes avoided the bottle of water sitting on my friend's desk. Then it was like a mountain of bricks and hit me like water. Water is always considered a weak person in many situations. Water is very adaptable. It can be gas, solid, or liquid, but its chemical state will not change through it. I think that this is my way through all the experiences I've ever experienced, through the loss and interests that I am still standing through through fighting and pain.
b) Water Quality: The right to water means not only the right to supply water properly and continuously, but also the right to water of sufficient water quality. Individual or household water must be safe and free from the risk of microorganisms, chemical substances, and radiation that pose a threat to human health. In addition, the water should have acceptable color, odor and taste for personal or domestic use. Actual accessibility: Water and appropriate water facilities and services must be within the security of all sectors of the population, defined as "near each household, educational institution, workplace". Water should be sensitive to adequate water quality, culturally appropriate, and gender, life cycle and privacy requirements.
Generally, water quality means water bodies for every useful application, especially the river standard. Water quality with better indicator value indicates that the water is clean. High water quality is suitable for human and animal consumption compared to low water quality. Water quality means that the characteristics of feedwater influence the suitability for a particular application, that is, how the water quality meets the needs of consumers. Water quality conditions indicate the level of pollutant composition and are thus related to human activity (Anhar et al. 1998; Mohd Kamil et al. 1997a; 1997b). The water quality of various water bodies varies depending on input amount, flow velocity, and amount of water (Mohd Kamil 1991; Wan Nor Azmin et al. 1997). Rivers are one of the important water sources and they are contaminated as their chemical and physical properties change to suit any target and function (Azizi et al. 1997).
