ABSTRACT
Leaching of trace elements from fly ash dumps to subsoil layer due to the rain water results in contamination of ground water. The ground water pollution due to fly ash deposition on land so occurring was assessed by simulating the disposal site conditions using two lysimeter with two different soils. Leachate was collected and analysed daily to help understand the phenomenon of leaching of fly-ash constituents in the environment. The trace metals and physico-chemical parameters of fly ash and soil used were measured before and after the experiment. Results of analysis of soil and fly ash samples were then compared with the results of lysimeter-I and lysimeter-II. The study reveals that metals respond differently at dumping site while reacting with soil and water.

The issue of managing solid waste (SW), especially in the major cities, is of growing concern to the municipal organisations in India. The present performance of the system is recognised to be unsatisfactory. This paper delineates an approach to quantify the satisfaction level of the residents as a measure of performance of the system and also presents a case study in a major city. The results show the validity of the approach.
