Ganges River

The water quality of rivers is deteriorating due to human interference. It is essential to understand the relationship between human activities and land use types to assess the water quality of a region. GIS is the latest tool for analyzing this spatial correlation. Land use land cover, and change detection are the best illustration for showing the human interactions with land features. This study assessed water quality index of the upper Ganges River near Haridwar, Uttarakhand, and spatially correlated it with changing land use to reach a logical conclusion. In the upper course of Ganges, along a 78-km stretch from Kaudiyala to Bhogpur, water samples were collected from five stations. For water quality index, physicochemical parameters like pH, EC, DO, TDS, CaCO3−, CaCO3, Cl−, Ca2+, Mg2+, Na+, K+, F−, Fe2+ were considered. The results of the spatial analysis were evaluated through error estimation and spatial correlation. The root mean square error between spatial land use and water quality index at the selected sampling sites was estimated to be 0.1443. The spatial correlation between land use change and site-wise differences in water quality index also showed a high positive correlation, with R2 = 0.8455. The degree of positive correlation and root mean square error strongly indicated that the water quality of the river in the upper course of the Ganges is highly impacted by human activities.

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,  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.
