| Abstract | Oligocene and Mio-Plio-Quaternary siliciclastic deposits constitute the most important deep aquifers of the Kairouanai-Sahel region. Considering the over-exploitation and contamination of the surface groundwater, recourse to use deep groundwater was crucial. These aquifers revealed three major hydrochemical facies: HCO$_{3}$/Mg, HCO$_{3}$/Na and SO$_{4}$/Mg water types. Rock–water interaction showed the main mechanisms are rock weathering and evaporation. Different parameters such as water quality index (WQI), sodium absorption ratio (SAR), percentage of sodium, residual sodium carbonate (RSC), magnesium hazard (MH) and permeability index (PI) were used to evaluate groundwater suitability for drinking and irrigation purposes. Results highlighted that groundwater is unsafe for irrigation based on PI, MH, RSC and salinity diagram. According to the WQI values, 10.25 % of the water samples had good water quality, 69.23 % were considered as poor water, 12.82 % were very poor water and 7.69 % were considered unsuitable for drinking purpose. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
