This papers models the saline water intrusion in the Bardez taluk of Goa.

The study is replete with hydrogeological maps and data. These include topographic contours, soil, landuse, rainfall, geology, location of observation wells etc.

This paper on Bundelkhand from their Water and Sanitation Perspective series of WaterAid presents how ecological degradation and faulty policies make drinking water scarce and less accessible.

A sharing workshop on groundwater organised by ACWADAM (Advanced Center for Water Development and Management) in Pune on 21/22nd May 2009 saw some very good presentations being made. Dr Tushaar's Shah's keynote speech provided an amazing big picture of groundwater use in agriculture. The presentation can be viewed on slideshare and the entire speech is available on YouTube in 4 parts.

The idea is to divert rainfall runoff into open wells as a means of harvesting rainfall runoff and increasing recharge into aquifers. Currently as of April 2009, the program is underway in a couple of states, mainly in Gujarat and Tamil Nadu, and other states are following suit. The program is ambitious in the sense that it aims to bring in millions of dug well owning farmers towards recharging. How will such a program be implemented, monitored and channeled so that the results are achieved to satisfaction? CAREWATER has designed a network of partners and is conducting studies to understand Dug well recharge and providing feedbacks to this national programme on artificial dug well recharge. Towards this purpose, since September 2008 we have created a partner base of organizations who along with our expertise are carrying out ground studies and analysis. Some of these results are available now on our website http://www.carewater.org (Please click on the link at the bottom of the homepage). We hope to keep updating this page as the program continues and wish to have more partners join our endeavor. In particular we have published a study of dug well recharge. The study is summarized below. We would like a larger discussion of the results of the study. Your comments below will be very useful to take this project forward more effectively.

Dr Kurien Baby, District Collector of Trissur, Kerala, and Solution Exchange Water Community are organizing a regional meeting to discuss the effects of the Mazhapolima program. The dates are 16-17 June 2009, and it will be held in Trissur.

Background

Kerala has among the highest well densities in India, and 71% of the population depends on them for drinking water. The aggregate household investment in the state on wells is pegged at Rs 1800 crore and they have a combined yield potential of 6.6 million cu m per day. That works out to a water availability of 197 litres of water per capita per day (lpcd), well above the government's prescribed norm of 140 lpcd. These wells are threatened. Despite an annual rainfall of 3,000 mm, 70% go dry in summer. The surface runoff is heavy, and therefore groundwater levels in several blocks have fallen sharply, and coupled with saline intrusion at an accelerated pace, have led to water quality problems.

A story from NGO MASS on successfully reviving an open well in Padiabadmal village in Orissa, that had been neglected for two decades. In a tube-well dependent drinking water supply system, an initiative by people of Padiabadmal, a tribal inhabited village in Western Orissa, has come as a refreshing fresh water splash.
