The status of groundwater situation in Madhya Pradesh monitored by Central Groundwater Board in its January 2011 report shows a decline as compared to levels in previous years.
Groundwater levels have declined in 57 per cent of wells, of which about 40 per cent show a decline up to 2 metre, especially in eastern and central parts of Madhya Pradesh. These declines may be due to deficient rainfall received in these areas during 2010 monsoon compared with those in 2009. Significant declines were found in Vidisha, Bhopal, Raisen, Sehore, Hoshangabad, Satna and Chhatarpur districts.
The present report gives an overview of the status of groundwater levels monitored during the month of January 2011. The monitoring of groundwater regime during January is particularly important in order to assess the status of ground water levels after the post-monsoon period during the peak of the Rabi season said Central Ground Water Board (CGWB) scientist Parvinder Singh.
Groundwater levels have risen by 43 per cent of wells. Wells showing rise are seen in the districts of Sheopur, Gwalior, Bhind, Guna, Neemuch, Mandsaur, Khargone, Katni, Jhabua, Damoh, Sidhi and Chhatarpur possibly due to higher positive departure of rainfall in these districts.
The CGWB North Central Region, Bhopal monitors ground water levels through a network of about 870 National Ground Water Monitoring Wells (dug wells, bore/tube wells) spread all over the State of Madhya Pradesh four times in a year in August, November, January, and May during the year. About 324 Piezometers, small-diameter observationsused to measure the hydraulic head of groundwater in aquifers were also being monitored in the State.
Most of the wells (82 per cent) in Madhya Pradesh show a decline in water levels in January 2011 when compared with those in the previous monitoring season (November 2010).
