Water quality change is caused by indirectly or directly sources such as human activities,uncontrolled sewage, or heavy metals and sediments. This study was conducted at two famousecotourism places in Jeli, Kelantan which are Lata Janggut and the new ecotourism place, LataKeding. The main objective of this study is to compare water quality index and heavy metals at thecascades. Twelve samples were collected from two points which are flowing water and stagnantwater in each cascade. Mann Whitney test was used to determine whether there are significantdifferences in concentration of each physical and chemical parameters between Lata Keding andLata Janggut. Spearman correlation was also used to determine the relationships between physicaland chemical parameters. This study found that Water Quality Index (WQI) in Lata Janggut is 69.07(Class III) and Lata Keding is 71.75 (Class III) which means that the water quality was slightlypolluted for both cascades. Therefore, Lata Janggut and Lata Keding require extensive treatment ifit will be used for water supply but still under control and safe to had body contact with the water.However, further monitoring are needed to avoid any environmental issues arise.

Groundwater quality is an issue of national concern in Jordan since it is the main water source for drinking, agriculture and industrial purposes. In this context, an attempt has been made to determine the suitability of groundwater in the Yarmouk Basin in Jordan for drinking purposes using the weighted arithmetic water quality index approach with the respect to the Jordanian standards for drinking water. Groundwater quality records from 15 sampling stations spread across Yarmouk Basin during 2008- 2015 are used. Seven physical and chemical parameters are selected to calculate the water quality index. These parameters are pH, total dissolved solids, total hardness, sulfates (SO4 −2 ), chlorides (Cl− ), nitrates (NO3 − ), and sodium (Na+ ). The relationship between the selected groundwater quality parameters is evaluated using the correlation coefficient. A strong relationship is found between several parameters such as Cl− with Na+ , total dissolved solids with Na+ , Cl− , TH and SO4 −2 and total hardness with SO4 −2. A moderate relationship is found between SO4 −2 with Na+ , TH with Cl− and Na+ , SO4 −2 with Cl− , Cl− with NO3 − and NO3 − with Na+ . Also, the mean concentration values of the physical and chemical parameters are almost below the maximum allowable level based on Jordanian standards for drinking except for two sampling locations. According to water quality index scale classification, the groundwater quality of the studied locations is in the excellent to poor water range with computed mean water quality index values range from 26.3 to 107.93. Out of 15 studied locations, ten locations are classified in the ‘Excellent water’ class, four locations as a “Good water” class, one as a “Poor water” class. None of the studied locations are classified in the “Very poor water” class and “Water unsuitable for drinking purpose” class. Temporal variations and spatial distribution of groundwater quality in Yarmouk Basin based on WQI are also evaluated. The WQI spatial distribution map clearly showed the best locations for drinking water in the Yarmouk Basin. Water quality indices are used to provide theoretical support to water managers and policymakers for proper actions on groundwater quality management

Studying groundwater quality in arid and semi-arid regions is essential significant because it is used as a foremost alternative source for various purposes (human and animal consumption, economic, agriculture and irrigation). Geographic Information System and Water Quality Index techniques were utilized for visualizing and evaluating the variations of groundwater quality in the studied area. Total twelve wells were sampled and twelve groundwater quality (chemical) parameters; pH, Total Alkalinity, Total Hardness (TH), Total Dissolved Solid (TDS), Electrical Conductivity (Ec), Potassium (K), Nitrate (NO3), Sulfate (SO4), Chloride (Cl), Calcium (Ca), Magnesium (Mg) and Sodium (Na) were analyzed in the laboratory. Inverse Distance Weighted technique was used as a useful tool to create and anticipate spatial variation maps of the chemical parameters. Predicting or anticipating other areas not measured, identifying them and making use of them in the future without examining samples. The results of this research showed that 8.3% of the studied wells have excellent groundwater quality, and almost sampling wells about 75% found in good groundwater quality, while findings of groundwater quality of 16.7% studied wells belong to poor water quality due to standards of Water Quality Index. Moreover, spatial analysis in term of groundwater quality map showed that Excellent groundwater quality was detected in well 3, very good groundwater potential was noticed in six studied wells (wells 2, 6, 8, 10, 11 and 12), and other sampling wells (wells 4 and 7) were observed as good groundwater quality, while poor water quality was observed in wells (well 1 and 5). Hence, spatial distribution maps showed that the almost groundwater quality in the area about 1046.82 km² (99.04%) are suitable for drinking purpose, whereas proximate 10.18 km² (0.96%) are observed as poor water quality and inappropriate for consumptions especially in the southern part of the area.
