This report by the Ministry of Environment and Forests (MoEF) deals with the applications of bioremediation to contaminated sites in India. Bioremediation is emerging as an effective innovative technology for treatment of a wide variety of contaminants and is an invaluable tool box for wider application in the realm of environmental protection.

Bioremediation approach is currently applied to contain contaminants in soil, groundwater, surface water, and sediments including air. These technologies have become attractive alternatives to conventional clean-up technologies due to relatively low capital costs and their inherently aesthetic nature. 

It includes phytoremediation (plants) and rhizoremediation (plant and microbe interaction). Rhizoremediation, which is the most evolved process of bioremediation, involves the removal of specific contaminants from contaminated sites by mutual interaction of plant roots and suitable microbial flora. 

The report documents the existing knowledge for the benefit of regulators, who evaluate the quality of environment and for practitioners, who have to implement and evaluate remediation alternatives at a given contaminated site. It is expected to provide basic understanding of the bioremediation mechanisms to the reader. The technical descriptions provided in this document concentrate on the functioning mechanisms: phytosequestration, rhizodegradation, phytohydraulics, phytoextraction, phytodegradation, and phytovolatilization.

This report under the WHiRL research project by the Natural Resources Institute (NRI) identifies the potential unintended impacts of water harvesting so that, if at all possible they are avoided altogether, but if these do occur, they are recognised at an early stage and steps are taken to mitigate their affects. It highlights evidence that is emerging about water harvesting in semi-arid areas, on how water if used inappropriately, can lead to inequitable access to water resources and, in the extreme, to unreliable drinking water supplies.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.

The following case studies describe the work of the City Managers' Association Karnataka in water management covering rainwater harvesting, watershed development, drinking water and water body restoration initiatives, set in an urban context. These initiatives were implemented in association with urban local bodies - Town Municipal Council Kundapura, Town Municipal Council Hosadurga, City Municipal Council Chitradurga, Bangalore Water Supply and Sewerage Board (BWSSB) and the Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC).Read More
