Ground Water Quality Evaluation in Raghunathapalli Watershed, JangaonDistrict,Telangana State, India

International Journal of Scientific Development and Research (IJSDR), 2023

Groundwater quality needs attention as it is the major source for drinking purposes. Raghunathapalli watershed is located in NorthWestern part of Jangaon District, Telangana state. The watershed is a tributary of AleruVagu (Musi Sub-basin) of Krishna Basin. There are 35 habitations using Deep Bore wells (30 habs) / Hand pumps (5 habs) which are essentially being used for drinking purpose. The chemical elements (9 nos) examined are pH, Total Dissolved Solids (TDS), Total Hardness (TH), Total Alkalinity (TA), Fluoride (F), Chloride (Cl), Iron (Fe), Nitrate (NO3) and Sulfate (SO4) with respect to its contamination spread as per ISO 10500: 2012 during pre and post-monsoon seasons. The spatial distribution and concentration of chemical elements is carried out by using spatial interpolation technique namely Inverse Distance Weightage (IDW) method from the point source data. Out of 9 elements; it is revealed that pH, Chloride (Cl), Iron (Fe), TDS, Total Alkalinity and Sulfate (SO4) distribution is within the permissible limits. The major problematic contaminant is Fluoride which is marginally affected (1.50-3.00 ppm) for 3 habitations during pre monsoon season and 7 habitations during post monsoon season. Total Hardness (> 600 ppm) is out of range in 1 habitation during pre monsoon season whereas the concentration of Nitrate (> 45 ppm) is out of range in 1 habitation during post monsoon season.

Micro watershed wise (a few thousand hectares of extent) water resource action plan is need of the hour especially for a hard rock terrain like Raghunathapalli watershed of Jangaon District. Geologically, the area is underlain by Quartzite and Pelitic Schist of Older Metamorphics and Leuco Granite / Grey Alkali FelpsarGranite Terrain (Peninsular Gneissic Complex) belonging to Archeans. The Archeans are intruded at several places by several Pegmatite Veins and Basic Dolerite Dykes. The average annual rainfall of the study area for the past 19 years is 946 mm and that of monsoonal rainfall is 746 mm. In order to do artificial ground water recharge, the study and analysis of parameters that control the ground water recharge is very important for effective ground water recharge. The spatio-temporal variations in rainfall, regional/local distribution in geological formations and geomorphic composition of various units have led to uneven occurrence and distribution of water resources. Different thematic layers like Geology, Geomorphology, Stream Network, Micro Watersheds, Digital Elevation Model, Contours (2m), Base Layers, Soil and Ground Water Potential maps are prepared using Geospatial technologies like Remote Sensing & GIS. Existing Recharge Structures are marked using 1:25,000 scale Survey of India Toposheets and new locations are updated with high resolution satellite imagery. Micro watershed wise Water Balance studies are carried out and Water Resources Development Action Plan is prepared using Ridge to Valley concept with new artificial recharge structures like Check Dams (22), Percolation Tanks (10), Contour Trenches (68Kms), Subsurface Dyke (2), Farm Pond (268), Recharge Pit (179), Recharge Shaft (16), Desilting Tank (24 nos) etc at suitable terrain conditions. Newly proposed locations for constructions of Rainwater harvesting structures in the gap areas will improve the ground water regime and improves the sustainability of wells for agriculture in the drought prone area of Raghunathapalli watershed. Thus Geospatial technologies are cost effective tools for management and conservation of water resources.

Morphometric Analysis of Raghunathapalli Watershed, Jangaon District, Telangana State, India

It enables the analysis of geohydrological characteristics of a drainage basin in relation to terrain features and flow patterns. The study area is located in Raghunathapalli watershed of Jangaon District. The majority of morphological characteristics show that the river basin features are subject to considerable geological (younger granites-PGC II) and Geomorphological controls (Elongation shape, high elevated area to surroundings, disposition of landforms etc). Analyzing the morphometrics of river basins yields important information for sustainable planning and management. It guides decisions on flood control, allocation of water resources, development of infrastructure, land use, soil conservation, and protection of ecosystems. Incorporating these findings into the planning process allows for the attainment of more robust and sustainable natural resource management, while reducing environmental damage and the risk of disasters.

Groundwater accounts for more than 80% of the rural domestic water supply in India. The main aim and objective of present research study is on applicability of satellite remote sensing techniques for sustainability of rural water supply sources of Medchal mandal of Ranga Reddy district. The integrated ground water prospects maps are prepared by using different thematic layers like Geology, Geomorphology, Structures (Lineaments), Hydrology etc. Drinking Water quality data of Rural Water Supply sources situated in Medchal mandal is studied for the parameters like Fluoride, Total Dissolved Solids, Total Hardness, Alkalinity, pH & Chloride to assess the spatial distribution of ground water quality in terms of potable or non-potable. Satellite Remote Sensing and GIS studies are employed by making use of other collateral data, Well Inventory data and Rural Water Supply data are incorporated. Groundwater quality data acquired are spatially interpolated using Inverse Distance Weightage (IDW) method to demarcate the spatial (locational) variations. Water demand is calculated for present (2012) and designed period of 20 years (2032). After detailed well inventory combined with integrated ground water prospects and quality studies, the problematic habitations are found out and plan of action and remedial measures have been proposed. The plan includes proposing water harvesting structures to either dilute the areas where the water quality problem is there or to increase the ground water reserves through artificial recharge in areas where there is sustainability problem.

RS and GIS based integrated study on hydrogeomorphic unit wise ground water quality evaluation for Nalgonda district, Telangana state

Groundwater is the main source of water for domestic, agriculture and industrial uses especially ... more Groundwater is the main source of water for domestic, agriculture and industrial uses especially in water scarce semi-arid regions. About 85% of rural and nearly 30% of the urban population depend on ground water for drinking and accounts for nearly 65% of the total irrigation potential in the country. The availability of ground water is dependent on many factors like geological history of the area, geomorphology, rainfall, geological structures that are controlled through the earth's history, porosity and permeability of soil or rock formations, depth of weathering and nature of weathered material etc. The quality of ground water deteriorates when there is overdraft of water for agriculture and industrial uses. The phreatic aquifer which was in use two decades ago, is not existing any more in major part of the study area and the water is being drawn from deeper aquifers beyond phreatic aquifers. As the ground water is the main source, states are being guided to prepare watershed wise Sustainability plans for all over‐exploited blocks in the country for taking up groundwater recharge and water harvesting structures by converging different schemes of MNREGS, NRDWP etc. This will improve the condition of ground water in space and time. An integrated remote sensing and GIS study is taken up for Nalgonda district for studying the hydrogeomorphic unit wise ground water quality variation and its impact by using other collateral data like soils, land use, command area, ground water exploitation, rainfall etc.
