Malaysia has over 10,000 brownfield sites which have yet to be registered. In fact there is limited information and controls on soil and groundwater contamination from these brownfield sites. In this study, four brownfield sites were examined in terms of the soil and groundwater quality to benchmark the heavy metal contents to be used as indicators of soil and groundwater contamination and to derive suggested benchmarking reference for remedial action to be taken. It also described briefly the possible remediation techniques to clean up the heavy metals in brownfield sites and the need for registration of brownfield sites towards sustainable development.

Wastewater disposal is currently a very serious problem with respect to quality of environment and sustainable development of the built-up area. This article deals with the processing possibilities of rain water and sewage wastewater in the area without public sewer system and central wastewater treatment plant. Absence of this system often leads to the provisory solutions of liquidation of water containing chemical substances, which then leads to the pollution of groundwater and bathing water. Evaluation was based on data from studies of waste water disposal for the territory of municipalities situated on the basin of significant watercourses.
