There are a number of legislations on the national level with the objective of conserving natural resources like water as well for addressing the problem of pollution. However, water being a state subject, the importance of state legislations on the same theme is that much more. Various states have either already formulated or are in the process of drafting legislations tackling natural resources like land and water.
Already about 10 states have formulated and adopted their own water policies, and the rest are in the process of doing so. The state water policies are comprehensive and treat water as a finite resource. The need to manage water resources in a scientific manner has been recognised in the policies and hence a lot of emphasis has been given to sustainable exploitation of water and groundwater resources.
Ground Water Year Book is based on the information generated by monitoring of ground water observation wells of NCT-Delhi during the field Season of 2011-12.
