A Comparison of water quality indices for Haraz River
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 3
Abstract
Rivers are considered as the most sustainable and clean water resource in all over the world. However, increasing the population and urban development make them to loss their sustainability. Therefore, quality control of these resources is an important task of environmental engineering. Given the importance of the Haraz River in water withdrawals for different uses and discharging different pollutants into it, mentioned river water quality assessment is essential. Parametric water quality measurements are difficult, in the other word, time consuming and costly. Three valid Quality Indexes namely National Sanitation Foundation Water Quality Index (NSF-WQI), Orgon Water Quality Index (O-WQI), and Universal Water Quality Index (U-WQI) are applied to assess the Haraz River water quality. Water quality has been assessed in a seasonal and annual basis at 10 stations. The findings indicated that water quality in Haraz River on average are good, very bad and relatively good in spring, summer, autumn and winter. Jill Janoik comparison method was used to compare the mentioned indices. The results of comparison indicated that the Oregon index is introduced as the most appropriate environmental quality index for monitoring and evaluating the Haraz River water quality.
