The studied area is the part of the Chota Nagpur Plateau and mainly named as Ranchi Plateau. A GIS integrated method is considered to delineate the ground water potential zone in this plateau region. This study is a systematic application and it has been considered five major controlling factors such as land use / land cover, geological structure, soil taxonomy, drainage density and surface steepness to detect the ground water potentiality.The weighted overlay method has been stimulated to demarcate the final ground water potential zone on the basis of weighted value. Each scheming factors are reclassified based on their assigning weighted value which are as certained from the prioritization of each class from all thematic layers according to their influence on ground water recharge. The result shows that more than 88% of the study area is under moderate to high potential zone of ground water. Among which 45% of area is under moderate potential zone, 38% under high potential zone and 4% is very high potential zone.

The population growth rate of this Municipality is 10.04 % from 2001 to 2011. This Municipality has around 71,618 houses which generate 153.48 Metric Ton of solid waste per day. The study has been carried out to select solid waste disposal site and to find out the suitable management strategies of solid waste system by using Analytic Hierarchy Process and Geographical Information System techniques. Five criteria have been taken for disposal site selection namely land use land cover, distance from road and railway, surface water body, Normalised Difference Vegetation Index and household density. Thematic layers are prepared using Remote Sensing and GIS technique. Weights were assigned to all the themes and their classes through AHP and finally overlay analysis technique was applied in Arc GIS Software to identify the disposal sites. The main problem is open dumping of solid waste without recycling, which resulted in environmental pollution for this Municipality. The study has been concluded with some fruitful management strategies which may be beneficial to the local people as well as municipal authority.

These once migrated tribes now contribute 67.44% of the total tribal population of the district (according to 2011 Census): they are Oraon, Munda and Santal. They are also the major scheduled tribes of the state West Bengal. In the district Jalpaiguri, these three tribes were brought by the British to work mainly as labourers in the newly formed tea gardens, railways and in the reserved forests. Tribes from Santal Parganas were brought to settle as agriculturists in this district. In the later stages, after the British left this region, the ownership of the tea gardens changed but these tribes didn’t leave the region and lived here permanently. The work attempts to understand the present habitat and characteristics of their houses. For doing this work, extensive fieldwork was done based on an interview schedule. Altogether, 650 households were chosen from all the 13 blocks of the district on the basis of random stratified sampling. The study reveals that the major concentration of these tribes is still found in the tea garden villages and few in the forest and non-forested plain areas.The Oraon and Munda tribes are largely found in the tea gardens but Santals are predominantly marked in nonforested areas, sustained on agriculture. In the tea gardens, besides, the garden provided semi-pucca houses, kaccha houses and informal houses are also common while in the forest areas and non-forested plain areas, kaccha houses are mainly observed made by earth, plant stalk and bamboo.

The source through which mostly the fluoride enters the human body is underground water.Fluoride compound (F ¯) is necessary for a certain content to eradicate the dental caries and to strengthen the bones. Fluoride remains in a certain amount in water. According to World Health Organization (WHO, 2002) the permissible limit of fluoride in underground water is 1.5 mg/L andaccording to Bureau of Indian Standard (BIS, 2009) the permissible limitof fluoride in underground water is 1 mg/L.Crossing this limit (1.5 mg/L) fluoride contaminates the water. If the same water is used mainly for drinking purpose then health hazard may occur. This health hazard is known as fluorosis. Person once attacked by this is never cured fully from this. Patients lost their ability to do work.This paper gains its importance to elaborate the physical and social causes of fluoride incursion into human health and negative effect of excessive fluoride consumption in five fluoride affected sample villages in Birbhum district. Physical causes are related with the invasion of fluoride mainly through fluoride contaminated water sources. On the other hand, social causes are associated with the personal behaviour and several constraints present in the respect villages. At last, impact has been elaborated briefly on the basis of clearly defined drinking water sources.
