KOCHI: The groundwater Department is upbeat as the rain water harvesting programme introduced in the State four years ago has started yielding positive results with the groundwater level in several parts of the district showing signs of improvement. In Ernakulam district, the department had bored 62 observatory wells in the past two years to monitor the groundwater level.
Groundwater is a primary source of fresh water in many parts of the world. Some regions are becoming overly dependent on it, consuming groundwater faster than it is naturally replenished and causing water tables to decline unremittingly. Indirect evidence suggests that this is the case in northwest India, but there has been no regional assessment of the rate of groundwater depletion.
