  • 1. Prepared by Prashant Adsul M. Tech. First Year (113184002) ES 680GIS for Environmental Planning and Management Under the guidance of Prof. A. K. Dikshit CESE, IITB
  • 2. Outline of Presentation Study Area Scope and Objective Water Quality Index (WQI) GIS Application OutputJune 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 2
  • 3. Scope and Objective  To study ground water quality of Solapur district using GIS software  To create Water Quality Index (WQI)  Generate Ground Water Quality Map based on the WQIJune 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 3
  • 4. Study Area Geographically Solapur is located between 17.10 to 18.32 degrees north latitude and 74.42 to 76.15 degrees east longitude. The district is situated on the south east fringe of Maharashtra State. The district in general has flat terrain Area = 14844.6 sq.kms 338.8 sq.kms is Urban area 14505.8 sq.kms is Rural area Tehsils: 11June 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 4
  • 5. Data for Analysis  Three Years (Years 2007-2008-2009) ground water Quality date used calculation of WQI  Data was downloaded from MPCB websiteJune 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 5
  • 6. Methodology for Data Interpretation Each of the groundwater samples were analyzed for various parameters such as pH, total hardness, calcium, magnesium, chloride, TDS, fluoride, nitrate, sulphate, manganese and total alkalinity Computing WQI of Groundwater, three steps: Data Source: MPCB website (2007-2008-2009) (Ramakrishnaiah et al, 2009)June 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 6
  • 7. Method for Calculation of Water Quality Index for Ground Water Step I Each of the selected parameters has been assigned a weight (wi) according to its relative importance in the overall quality of water for drinking purposes. The maximum weight of 5 has been assigned to the parameter nitrate due to its major importance in water quality assessment. Magnesium which is given the minimum weight of 2 as magnesium by itself may not be harmful Step II The relative weight (Wi) is computed (Ramakrishnaiah et al, 2009)June 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 7
  • 8. Method for Calculation of Water Quality Index for Ground WaterJune 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 8
  • 9. Method for Calculation of Water Quality Index for Ground Water Step III A quality rating scale (qi) for each parameter is assigned qi = (Ci/ Si) x 100 where qi is the quality rating, Ci is the concentration of each chemical parameter in each water sample in mg/L, and Si is the Indian drinking water standard for each chemical parameter in mg/L according to the guidelines of the BIS 10500, (2004-2005 (Ramakrishnaiah et al, 2009)June 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 9
  • 10. Method for Calculation of Water Quality Index for Ground Water SIi is the subindex of ith parameter qi is the rating based on concentration of ith parameter n is the number of parameters (Ramakrishnaiah et al, 2009)June 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 10
  • 11. Water quality classification based on WQI value All WQI calculations are performed in ExcelJune 8, 2012 Water Quality Mapping for Solapur District using GIS Prashant Adsul, CESE IITB 11
