Anthropogenic activities leads to deterioration of groundwater quality: A study of Mayyanad and Edamulakkal panchayats of Kollam district in Kerala
Kerala is a rain blessed state in the country, but due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity. This paper sheds light on groundwater quality issues in two panchayats of Kerala Posted on 22 Feb, 2013 10:07 AM

Kerala is a rain blessed state in the country. It has highest  number of wells, when compared with other states. However due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity during summer months in most districts of the state. Further over extraction and dependence of groundwater for domestic use from the dug wells especially in rural pockets has resulted in several groundwater problems. In this backdrop the paper in  The Ecosan- An International Quarterly Journal of Environmental Science, sheds light on groundwater quality issues in two panchayats of Kerala.

Assessing the land use change and its impact on water resources: A study on the Mula and Mutha rivers catchment area in Pune
Analysing the changes in land uses between 1989 and 2009, this paper assesses the impact on water balance in Mula and Mutha Rivers catchment upstream of the city of Pune Posted on 17 Feb, 2013 09:11 PM

Land use changes  hydrologic system and have potentially large impacts on water resources. An assessment in an area with seasonally limited water availability and which is subject to rapid socio- economic development and population growth will provide an exemplary view on the local impacts of major recent developments in India. In this backdrop this paper analyzes past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. The aim of the paper is:

  • assess the land use changes between 1989/1990 and 2009/2010
  • analyze the impacts of these changes on the long-term water balance components in the Mula and Mutha Rivers catchment upstream of the city of Pune.

Influence of anthropogenic contamination on fluoride concentration in groundwater: A study of Mulbagal town, Kolar district, Karnataka
Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. This paper analyses the Fluoride contamination, one such example of geogenic contamination, widely found in the Kolar district of Karnataka. Posted on 15 Feb, 2013 04:53 PM

Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. Fluoride contamination is one such example of geogenic contamination that is widely found in the Kolar district of Karnataka. However, the fluoride levels in the town of Mulbagal are lower than those in the surroundings. Earlier, a study was conducted on the impact of pit toilets on the groundwater in the area. The present paper investigates the presence of any link between these two phenomena.View of Mulbagal Town, Kolar District, Karnataka

Process of formation of Jajmau Area Water Partnership in Kanpur, Uttar Pradesh – Problems and solutions
Industrial effluents and sewage water are being diverted to the river Ganga by the cities and towns through which it passes. Nestled on the banks of Ganga, Kanpur, a highly urbanized and industrial city is polluting it most. Apart from the Government of India’s recently constituted National Ganga River Basin Authority, civil societies and NGOs too are putting rigorous efforts to make Ganga pollution free. Though the city has several big and small industries, the leather industries located in Jajmau, the oldest part of the city add to the problem of pollution in the river to a large extent.
