The growing interest in alternative water supplies is impelling societies, government bodies and industries throughout the world to conduct research and discuss the feasibility of reuse of treated wastewater. Treated wastewater has emerged as an affordable source of water supply worldwide. Designing of wastewater reuse systems involves consideration of multiple criteria such as technical, social, economic, environmental, legal as well as multiple stakeholders. The objective of the present study is to develop a multi‐criteria decision‐making (MCDM) approach using Analytical Hierarchical Process (AHP) for the selection of significant criteria and sub‐criteria governing the planning and execution of water reuse systems considering the local conditions and end users. The weightage of the individual parameters is obtained. The results indicate that the weightage of different criteria varies for different stakeholders. The analysis may help in developing a holistic approach for reuse of treated wastewater inducing improved decision‐making at authoritative levels.

In India, one of the major sources of water is the groundwater. Currently, its quality is being degraded due to many reasons such as intrusion of waste from various chemical factories and other industries. The objective of the study was to analyze the groundwater quality in the vicinity of the Kala Sanghian drain, Jalandhar. The drain carries waste from various industries in Jalandhar and is unlined which might affect the quality of the nearby groundwater. The physiochemical and heavy analysis was carried out on 30 samples collected from different locations of varying depths along the drain. It was observed that the values for some of the parameters are exceeding the permissible limit. The reason for dwindling quality of water in the area may be due to the discharge of the industrial waste into the Kala Sanghian drain. Hence, quick and reliable monitoring measures are essential for safeguarding the water quality. Geographic Information System was used to map the parameters values in terms of WQI in spatial domain which would help in better visualization of the problem and improved decision making.

Air pollution is one of the foremost and grave public health and environmental anxiety in most of evolving countries. Objectives: The objective of this paper is to provide insight details about current situation of air quality across various cities present in India, along with countless origins and effects of air pollution. An attempt is made to make people aware about various types of gases and particulate matter present in air highlighting their effects on environment along with the various ways of overcoming this situation. Methods: The National Air Quality Index (NAQI) ensures comparison amongst various cities so that new measures can be formulated in order to decrease the quantity of particulate matter present in air. In this paper concentration of various pollutants along with various harmful gases for various cities of India are analyzed based on past NAQI data thereby highlighting those areas which are under extensive menace of pollution. Findings: It has been perceived from past few years that the rate at which Urban Air Pollution across India has grown is alarming due to severe unsafe web of particulate matter (PM) and harmful gases present in air that living organism’s breath. Levels of particulate matter are extremely higher in all cities of India. Only few cities are such that can be emphasized where Air Quality Monitoring (AQM) has started due to which they show some enhancement in quality of air but mostly affected areas are small and medium sized towns which suffer from phenomenal spurt in pollution in very critical manner. Due to increase in immense number of vehicles, industries and manufacturing units has resulted in excess assembly of pollutants in air making air pollution as a state of national emergency across various cities around the country.

Background: Anthropogenic activities are major source of water pollution, particularly, because of haphazard dumping of heavy metals which get accumulated through trophic levels posing a severe risk to the surroundings. The removal of heavy metals from wastewater is, thus, very significant. Objective: The objective of the present study is to use rice husk, tea waste and orange peel for removal of Pb (II) ions by adsorption and to develop equilibrium and kinetic studies data for the same. Method: The batch process of adsorption was used and the concentration of lead adsorbed was measured titrimetrically. Findings: The maximum removal efficiency has been observed as 88% in tea waste and 80% in rice husk and orange peel. The equilibrium data obtained at optimized conditions for all the metal ions studied has been subjected to the isotherm models used for adsorption, namely, Langmuir and Freundlich. Further, to examine the kinetics for adsorption of Pb (II) ions on the adsorbents under study, pseudo first order and second order equations have been analysed. Thus, it was concluded that the utilization of low cost waste materials for treating wastewater using adsorption is effective, ecofriendly, locally available causing no pollution along with solving the problem of waste disposal.
