Geochemical assessment of groundwater in a desertic region of India using chemometric analysis and entropy water quality index (EWQI)

This study takes a look into groundwater quality at Ugbor Dumpsite area using water quality index (WQI), 2-Dimensional (2-D) geophysical resistivity tomography and vertical electric sounding (VES).The geophysical resistivity methods employed revealed the depth to aquifer, the geoelectric layers being made up of lateritic topsoil, clayed sand and sand. Along the trasverse line in the third geoelectric layer of lateral distance of 76 m to 100 m is a very low resistivity of 0.9 to 13 m from a depth range o f about 3 to 25 m beneath the surface- indicating contamination. Water samples were collected and analyzed at the same site during the raining season and during the dry season. The value of water quality index during the raining season was 115.92 and during the dry season was 147.43. Since values at both seasons were more than 100, it implies that the water is contaminated to some extent and therefore poor for drinking purpose. The Water Quality Index was established from important analyses of biological and physico-chemical parameters with significant health importance. These values computed for dumpsite area at Ugbor were mostly contributed by the seasonal variations in the concentrations of some parameters, such as, conductivity, total dissolved solids, hardness, alkalinity, chlorides, nitrates, calcium,Â phosphates, zinc, which showed significant differences (P<0.01 and P<0.05) in seasonal variation.

erkembangan Kota Bogor tidak bisa dilepaskan dari keberadaan dua sungai utama yang melewatinya, yaitu Sungai Ciliwung dan Sungai Cisadane. Aktivitas penduduk di sekitar Daerah Aliran Sungai (DAS) Sungai Ciliwung dan Sungai Cisadane sangat berpengaruh terhadap kualitas air sungai, karena sebagian dari limbah buangan hasil aktivitas tersebut langsung dibuang disungai. Analisa ini bertujuan untuk mengetahui kualitas air Sungai Ciliwung dan Sungai Cisadane Kota Bogor pada tahun 2017. Data yang digunakan dari pengambilan sampel air di lapangan pada bulan Agustus di 10 titik pengamatan. Selanjutnya hasil dianalisa menggunakan Metode Water Quality Index (WQI). Parameter yang digunakan meliputi Temperatur, Total Dissolve Solid, Turbiditas, pH, DO, Nitrit, Amonia, Fosfat, Minyak dan Lemak serta Total Coliform. Parameter tersebut dianalisa secara insitu menggunakan alat portable Water Quality Checker juga melalui analisis laboratorium. dan hasilnya bahwa kualitas air yang masuk ke Kota Bogor mengalami penurunan setelah melewati area Kota Bogor.

The low level of water in rivers in Iraq leads to poor water quality, on that basis; we need to assess Iraq's water resources for uses of irrigation and drinking water. This study present a model accounts for ground water quality by using a water quality index (WQI) for the region defined between the city of Kut and the city of Badra in Wasit province. this study relies on a system of wells set up along the path through the Badra –Kut and around it up to 78 wells. The study showed poor quality of ground water in the region of study and it is unsuitability for irrigation and drinking water, as well as provided a solution to the water accumulated in the Shuwayja to reduce the bad effect on groundwater by using a system of branch and collection canals then pumping at the effluent of Al Shuwayja in seasons of rainy season ..Water quality index calculated depend on the basis of various physic-chemical parameters as PH, Ec , TDS, TSS, Nacl , SO4 ,Na , and Mg. The resultant and analytical are present with use of Arch GIS program – geostastical analysis for the water index and water quality parameters
