Surface Water Quality and Key Water Sources

Surface Water Source Water Quality Index (WQI) is a general water quality index that indicates the overall condition of a river without specifying its usability. Similarly, stating that a person's body is healthy or ill does not directly indicate what that person can do (a person who is not severely ill may still be able to perform certain tasks). Therefore, it is called the General Water Quality Index. It is used to indicate water quality levels as very good, good, fair, poor, or very poor. The Unweighted Multiplicative River Water Quality Index is a method used to disseminate water quality information to the public using simple, concise, and non-complex terminology, as used in the United States. It is one of the methods used in preparing reports submitted to the U.S. House of Representatives (developed by Brown, R.M., et al. 1970). The development of the instrument for assessing water quality as described above had the following objectives: 1. To enable administrators and the public, who may lack scientific background, to easily understand water quality issues. The scale is out of 100 points, categorized as very good, good, fair, poor, and very poor. 2. The Surface Water Source Water Quality Index (WQI) should be related to or consistent with surface water source standards for joint application. Based on the aforementioned objectives, an instrument for assessing overall water quality, namely the Surface Water Source Water Quality Index (WQI), was developed.
