Solid waste management (SWM) is one of the most neglected aspects of India's environment and the recent Municipal Solid Waste (Management and Handling) Rules 2000 have made it mandatory for the administrative authority of any area to undertake responsibility for all activities relating to municipal solid waste management (MSWM).

The industrial development and growing population in India is in demand of more energy. Coal based thermal power generation is a major source of energy and is expanding at a very high rate leading to over exploitation of coal reserves, which is causing adverse impacts on the environment.

The study related to assessment of various chemical constituents in the groundwater, their origin and suitability for human use has been carried out in the Chaliyar river basin of Kerala. Groundwater samples were collected from 27 open dug wells and 7 bore wells, and analyzed.

Tehri hydroelectric project of 2,400 MW capacity, the Asia's highest dam constructed on the Bhagirathi river in Uttarakhand is one of the most debatable dams of the country. The fluvial system of Bhagirathi and Bhilagana has been converted into a huge lentic water reservoir. Therefore, the information on periphytonic diversity before impoundment is very important.

This paper presents a detailed computational fluid dynamics (CFD) based approach for modeling thermal destruction of hazardous wastes in a circulating fluidized bed (CFB)incinerator.

The performance of electrocoagulation method with aluminium, iron and hybrid A1/Fe sacrificial anodes in the treatment of arsenite [As9III) and arsenate(As(V)] in pharmaceutical industrial effluents was investigated. Several working parameters, such as pH, current density, contact time and metal ion concentration were studied in attempt to achieve optimum removal efficiency.

The effect of irrigation by the effluent of paper industry versus well water on properties of soils in three seasons was studied in Nagpur district, Maharashtra. The effluent had high total dissolved salts and biological oxygen demand than well water.

The ground water samples collected from different tehsils of Ujjain district were analysed in the laboratory for electrical conductivity (EC), pH, cations (Na+, K+, Ca2+ and Mg2+) and anions (CO32-, HCO3-, Cl- and SO42-). The ground water quality map of the district was generated using ERDAS-IMAGINE 8.7 software showing different categories.

Groundwater quality data on physico-chemical, bacteriological and heavy metal concentrations in three cities (Faridabad, Allahabad and Varanasi) in Ganga-Yamuna basin was subjected to multivariate analysis using SPSS. The factors extracted showed high loading (>0.3) of various parameters, such Cl, conductivity, TDS, hardness, Na, Mg and SO4 indicating contamination due to leaching of pollutants.

The ground water quality in Coimbatore city along the Noyyal river during pre-monsoon and post-monsoon seasons in 2005 is discussed in this paper. Water samples were collected from 12 wells on either side of the river.
