Abstract
An overview of groundwater development in Bangkok, Thailand, is provided and the paper highlights the environmental consequences of unplanned large-scale groundwater utilization. The effectiveness of the control measures adopted so far to address the issue of land subsidence is discussed. Recent initiatives and studies are analysed and the impediments to effective implementation of control measures are identified. Challenges faced by the Department of Groundwater Resources, which is responsible for groundwater development and management, are indicated. Recommendations are then put forward for improvement of the groundwater management system.
