Environmental Pollution and Management - A Civil Engineering Course under the National Programme on Technology Enhanced Learning
enhancing the quality of education through specially designed and interactive courses on environmental pollution and management Posted on 13 Oct, 2010 10:32 PM

This Civil Engineering Course under the National Programme on Technology Enhanced Learning (NPTEL) on the broad subject of Environmental Pollution and Management is being carried out by Indian Institute of Technology’s and the Indian Institute of Science, Bangalore as a collaborative project supported by the Ministry of Human Resource Development (Government of India) to enhance the quality of engineering education in the country, by developing curriculum based video and web courses. In these web based lectures, the authors have developed the subject in detail and in stages in a student-friendly manner. The broad group of Environmental Pollution and Management is structured into modules on the following topics:

Groundwater quality monitoring and evaluation in and around Greater Guwahati – A research report by National Institute of Hydrology
The study deals with the detection of trace elements – Cu, Co, Cd, Zn, Fe, Mn, Ni and Pb along with pH and ORP in the groundwater of Guwahati and its adjacent areas. Posted on 30 Jun, 2010 07:25 PM

The study deals with the detection of trace elements – Cu, Co, Cd, Zn, Fe, Mn, Ni and Pb along with pH and ORP in the groundwater of Guwahati and its adjacent areas. Toxicity of a metal depends on its concentration, which adversely affects any biological activity. Almost all the metals are toxic at higher concentrations, few in low concentrations and few others even in trace like As, Pb, Hg, Cd etc. The presence of such metals in groundwater is a subject of concern. Groundwater that contains higher amount of metals affects public health to a great extent when it is used for drinking and domestic purposes.

Groundwater quality monitoring and evaluation in and around Greater Guwahati - A research report by National Institute of Hydrology
In this study, groundwater quality monitoring and evaluation of Greater Guwahati is presented based on the physico-chemical characteristics of thirty samples collected on grid pattern. Posted on 29 Jun, 2010 11:05 AM

In this study, groundwater quality monitoring and evaluation of Greater Guwahati is presented based on the physico-chemical characteristics of thirty samples collected on grid pattern. The various parameters analyzed include pH, electrical conductivity, temperature, Dissolved Oxygen (DO), Total Dissolved Solids (TDS), alkalinity, hardness, Na+, K+, CA++, Mg++, NO3-, SO4--, Cl- and F-. The results were compared with water quality standards prescribed by BIS and WHO.

Preliminary hydrological investigations for Deepar Beel and strategies for its monitoring and management - A research report by National Institute of Hydrology
The study presents a preliminary hydrological investigation of the Deepar Beel, a natural freshwater lake near Guwahati, and notes the theoretical aspects of the techniques to be used. Posted on 23 Jun, 2010 07:30 PM

The study presents a preliminary hydrological investigation of the Deepar Beel, a natural freshwater lake near Guwahati, and notes the theoretical aspects of the techniques to be used, methodologies and instruments for conducting a detailed study of the natural processes at hand.

Deepar Beel acts as a natural stormwater reservoir during monsoon period and is greatly influenced by the rapid urbanization and improper land use pattern of Guwahati. It receives a large portion of sewage of the city, but the preliminary investigations reveal that the Beel is largely free from significant levels of pollution. This is due to the dilution effects of large storm water runoff during monsoons as also the release of the Beel water to river Brahmaputra through the Khanajun outlet. Yet, the soil quality is found to have deteriorated to a large extent.

Various parameters of soil and water quality indicate that the process of eutrophication is in progress in this wetland. Although many trace elements are present in the Beel sediments, no known toxic effects are observed on aquatic life. Increasing sedimentation and reduction in lake water capacity and inflow are also observed.

Groundwater quality in Greater Guwahati with respect to trace elements - A research report by the National Institute of Hydrology
The study on groundwater quality of Greater Guwahati analyses various trace elements in samples of drinking water. Posted on 22 Jun, 2010 08:08 AM

The study on groundwater quality of Greater Guwahati analyses various trace elements in samples and ascertains that their concentration is much higher than the tolerance limit prescribed for drinking water. The trace element analysis focuses on metals such as Cu, Co, Cd, Fe, Zn and Pb.

Owing to the inadequacies of piped water supply, the Greater Guwahati area depends on groundwater from ringwells and tubewells for drinking purposes. Groundwater is mostly polluted from the effluents discharged by industries on land, seepage from sewage lines & tanks and application of pesticides on agricultural land. Due to the low flow velocity, groundwater once contaminated will remain so for longer periods. Metals assume significance because of their greater toxicity, accumulative and non-biodegradable behavior. 

Approach and achievements of individual water management by Dr Choudhury of Guwahati
In the recent past, Dr. Dipul Choudhury from Guwahati (Assam), managed to ensure rainwater harvesting arrangements in his newly constructed multistoried building at Tarun Nagar, Guwahati (Assam). The results have been very satisfactory and he is proudly nicknamed "Resident Water Manager". Posted on 18 Jun, 2010 10:07 PM

Guwahati college of architecture receives second prize for presenting integrated water management in college campus
The presentation by Anuj Bhajanka and Avinash Chirania from Guwahati college of architecture details water management system designed by them for their own college Posted on 09 Jun, 2009 12:18 PM

Currently the college has a daily water consumption of 17.8KL and inadequate supply. The design integrates water conserving devices such as waterless urinals and eco-san toilets with grey and black water treatment systems and rainwater harvesting.
