The report presents a hydrochemical study of the groundwater of Sagar, Madhya Pradesh carried out during 1996 to examine the suitability of water for drinking and irrigation purposes. Under the study, thirty-five water samples representing the shallow groundwater of the region were collected during pre-monsoon and post-monsoon seasons in the month of June and November 1996 respectively.Read More

The study looks at chemical characteristics of groundwater in Jammu and Kathua on the basis of thirty water samples collected from open wells during July and December, 1997. The water quality has been evaluated for irrigation and drinking purposes. The suitability of water for drinking purposes has been compared with the standard norms i.e., BIS, 1983 and WHO, 1984.Read More

The study analyses the surface and groundwater quality of Ghataprabha representative basin during pre-monsoon and post-monsoon seasons. It looks at the primary impact of land use and cropping pattern on water quality using physico-chemical analysis, geo-chemical classification of groundwater samples and monitoring of groundwater quality.

Streeter-Phelp’s model is applied to understand the variation of dissolved oxygen along the course of the river from a point source. The study attempts to understand the impact of irrigation return-flow and use of pesticides, fertilizers & manures on surface and groundwater quality. The literature review offered indicates a dearth of studies on the subject for hard rock catchments and puts forward the need to do basin-wide as against area-wide studies.Read More

As part of its committment to provide safe drinking water to its rural communities, the Karnataka State Government as part of its World Bank-assisted Jal Nirmal Yojana program, implemented through the Karnataka Rural Water Supply and Sanitation Agency, took an initiative to adopt a Geographical Information System (GIS) approach to develop a Spatial Information and Knowledge base on groundwater quality of Karnataka.

As part of this effort, a comprehensive study of the quality of groundwater being supplied in rural areas has been taken up and water quality mapping, building of GIS database and profiles have been generated for 27 districts and 175 taluks. For this the chemical analytical data of water samples collected from bore wells in different villages by the Rural Development and Engineering Department (RDED) have been used. In all about 1,54,491 groundwater samples have been collected and analysed for 14 major parameters covering 33,647 villages out of the total 56,682 villages in the state.

This section contains individual district-wise profile files. Each district profile contains district and taluk level information across various study parameters, followed by representation of the analysis of the data through district level GIS maps.

All the district profiles can be downloaded as one single file below.
