Summary form only given. Most of the existing solid waste disposal sites in Malaysia are practising either open dumping or controlled tipping because the technology of proper sanitary landfill practice is not totally implemented. The environmental conditions from these sites are thus expected to be bad especially in terms of the contamination of soil, air, surface and underground water, and also impacts on flora and fauna including human. The contamination associated with solid waste disposal sites involved three major environmental compartments or media, i.e. the atmosphere, water and soil. This 'cross media' or 'multimedia' impacts phenomenon has been recognised in various countries as being of potential importance and complicated. This study discusses on the development of simple evaluation systems by using the Delphi Approach, which emphasises the development of weightage for different parameters selected in the evaluation procedures.
