Water is the basic need for any life on earth. The process of purification mainly with chlorine, for suiting it to human needs increases its hazardous characteristics due to formation of by-products when chlorine reacts with natural organic matter. Trihalomethane is one such by-product which is hazardous to human and animals consuming such water. Trihalomethanes are commonly formed as the by-product such as bromodichloro methane, di-chlorobromo methane, bromoform and chloroform. This paper discusses the factors affecting the formation of Trihalomethane and different technologies available to reduce the formation of Trihalomethane.

Estimating changes of coastal land using Geographic Information Systems (GIS) and Remote Sensing, over
a period can provide insights into sustainable use of natural resources, especially land. In this study, images
captured from Landsat Multispectral-scanner (MSS), Landsat 5 and Landsat 7 of Alappad, a coastal town
in Kerala in 1990, 2001, 2005 and 2009 are used to elucidate spatial distribution of land and land use pattern
over a period of two decades. During 1990 - 2009, remarkable decline of vegetation and sand from coastal
areas is seen. Understanding land use patterns over a period is essential for decision makers to implement
sustainable land use measures and policies.

Contamination of water bodies due to uncontrolled discharge of industrial waste dumping of municipal and household trash is one among the critical environmental quandaries faced today. This leads to the eutrophication of water bodies due to a higher concentration of elements such as phosphates and nitrates. As a potential answer to this quandary, this work tried to examine the impact of adding nano-sized coating of graphene on coastal black sand in the adsorption of heavy metals. In the current research, batch adsorption methods are employed to achieve Chromium adsorption (c-Adsorption) on nanocomposite and rich black coastal sand. The experiment is carried out with the anticipation of identifying the basic characteristics of clay soils, the effect of adsorption of chromium in soil in nanoscale coating and the dependence on concentration, pH values and contact time.

Industrial waste disposal is one of the major causes for the contamination of water bodies and soil. This leads to increase in the amount of elements like phosphorous in the water bodies. As a possible solution to this problem, we investigate the effect of introducing a nano sized coating of graphene on coastal sand in the adsorption of phosphate. In the present study we employ batch adsorption techniques to perform Phosphate adsorption (p-Adsorption) on rich black coastal sand and nano composite. This will help us in understanding the physical properties of clay soils, the effect of nanoscale coating on the adsorption of phosphate in soil and its dependence on contact time, concentration and ph values.

While electricity authorities are trying to meet the power demand on one side, much of energy is getting wasted on other end. At some points in a day, especially during peak hours, energy need to be borrowed from neighboring states or the central pool, to manage the demand; or otherwise, load shedding need to be adopted. This high demand can be solved either by generating more power by installing power stations or by controlling the power usage at the consumer side. New power stations are not a feasible and viable solution. Major electrical wastages in house hold appliances can be considerably reduced with proper monitoring and control. Switching off fans, TV, lights etc. when not in use is a simple task which many fail to do. Here an intelligent or smart meter is introducing, which can carefully monitor the usage pattern and reduce the load during peak hours and also saving electricity cost by 25-30%. The energy meter is connected with the GSM module and get updated units of energy consumed by consumer via Arduino and also turn on/off the appliances using IoT via switching mechanisms.

The efficient groundwater utilization, planning and management, is inconceivable without the proper recognition of potential zones. The present study aimed to assess the groundwater potentiality in district Swat, Khyber Pakhtunkhwa Province, Pakistan. The weighted overlay analysis methodology is used in this paper. A total of seven influence factors were used in the present study, viz. slope, drainage density, geology, rainfall, soil, land use/land cover and lineament density. The weight and score of each influencing factor is computed using multi influence factor (MIF) techniques. Within each influencing factor the subclasses were assigned a weightage of (A) (major effect) and (B) (minor effect) depending upon their effectiveness to the recharge of aquifers and groundwater potentiality. The combined weightage of both major and minor effects (A + B) was considered for computing the relative effect which was used to compute the score of each subclass within each influencing factor. The thematic layers were then integrated with weighted overlay using ArcGIS 10.2.1 and groundwater potential zone were delineated. The delineated groundwater potential zones were classified into four categories, i.e., (1) poor, (2) good, (3) high and (4) very high potentiality. The findings revealed that very high groundwater potential zone cover an area of 342.57 km2 (6.7%), high 1506 km2 (29%), good 2384.8 km2 (45.91%) and poor 960.28 km2 (18.48% of total area). The results of this paper are believed to be useful for effective groundwater harvesting and management and can also be used as helping material for future research work.

Safety plays a key role in today's world and it is necessary that noble safety systems are to be practiced in places of work and education. Even the smallest negligence can pave a way to large scale environment catastrophe. India has already witnessed such a deadly disaster which took life of thousands and lead other lives into total darkness - `The Bhopal Gas Tragedy'. The idea for our project has been born as a measure that could reduce the impact of such disasters in the future. Here, a device had been designed which could detect the presence of harmful gases and give an indication if the amount of polluting gases exceed a certain limit. The device can play a very vital role as it can be implemented in any industry where there are chances of discharge of such polluting gases and also can be attached to the exhaust pipe of vehicles.

Cancer, is a group of diseases characterized by the cells having the potential to invade surrounding cells and to trigger exponential growth in them. A group of these cells, with similar cancerous behavior forms a tumor. Thus the removal of these cancerous cells from the body turn out to be a hectic process as the ambience in which they grow remain unaltered. Thus, here we bring in the concept of decade old “Reverse Current Technology”, wherein the direction of a current could be reversed without altering its magnitude. Identifying the magnitude and direction of the current passing through the cancerous cells, and applying this concept would help in suppressing this favorable condition for the tumor. This concept is backed by the fact that, the electric field produced by a current in one particular direction will be opposite to the electric field produced by the same current in the reverse direction. By this method, tumor is restricted to a defined area and thus the removal process is simplified to the core.

In recent times, ensuring availability of adequate supply of potable water for its citizens is of great concern for nations across the globe. Water purification is a matter of high immediacy in developing countries, where enough supply of clean drinking water is unavailable. Globally, in consideration of the water-related diseases, assurance of an affordable, scalable water treatment infrastructure is of paramount significance. Many states in India face are confronted by scarcity of safe water and pollution, evoked mainly by anthropogenic activities. Majority of the population is unable to either access or afford safe drinking water. More than 60% of this population rely on groundwater for the purpose of drinking alone and on surface waters for all other purposes. In this era of high-water necessity, the aim of this paper is to develop a handy personal, water purifier, which is a ubiquitous, cost-effective access to healthy potable water for humans. This portable water purifier is a multi-stage filter constituted of a fabric filter, graphene-oxide coated sand filter, vetiver grass filter, and a UV filtration system. Water quality test show drastic reductions in the total dissolved solids (TDS), hardness, chloride and calcium ions. Implementation of this filtration unit in water-stressed countries is expected to serve as an efficient and affordable appliance for daily consumption of water.

Concomitant with careless human interference in the delicate environmental balance, the Earth’s surface is witnessing a variety of changes in land use and land cover (LULC). Acquisition of a sound understanding of LULC is an important aspect of maintaining a sustainable, benign, healthy environment. The present work highlights a spatiotemporal study on the LULC features of Alappuzha District, an ecologically fragile area in southern Kerala, a state in South India. The study area faces diverse environmental challenges including decline of landforms, rising sea levels, population expansion and anthropogenic encroachments on the ecological balance. This investigation compiles an audited account of the modifications, in each class of LULC, using geospatial technologies. We interpreted satellite imagery from the Landsat 8 and the Landsat multispectral scanner for the years 1973 and 2017. The LULC aspects were categorized into seven classes: waterbody, waterlogged area, mixed vegetation, built-up land, uncultivated area, paddy field and sandy area. Our findings affirm that the expansiveness of the built-up land area is directly proportional to the growth of the population. Advanced technologies such as remote sensing and geographic information system accentuate alterations in land use patterns over time and the extent to which the changes affect the human population and the natural habitat. We verified the results of our research by assessment of accuracy and ground truth confirmation of the LULC features.

Air pollution has an appalling effect on human health and our planet has a whole. This study quantifies air pollution using a parameter – Air Quality Index and compare the pollution of air in six major sites across Kerala, India (South over bridge and Eloor in Ernakulam district, Pettah and Veli in Thiruvananthapuram district, Chavara and Kadappakada in Kollam district). The significant differences in seasonal variation of pollutants in the three districts are also studied. The conclusion of the study shows: a) Air Quality Index in all these areas is predominantly determined by Particulate Matter concentration; b) Ernakulam district has the highest Air Quality Index among both industrial and residential areas and Kadappakada, Kollam has the lowest Air Quality Index among all the six areas studied; c) The air quality deteriorates during winter and summer because of limited pollutant dispersion.
