Recent projects have led to a better understanding of the limitations, obstacles and advantages that accompany investigating and delivering risk-based contaminated site management and remedial technologies to environmental work in Indonesia. For instance, non-technical regulatory limitations need to be overcome as the Ministry of the Environment and Forestry has recently started to impose environmental clean-up directives based on the current environmental regulations. Theses groundwater and soil regulations are interpreted somewhat vaguely, providing additional challenges of stakeholder negotiation and advocacy when implementing environmental site strategies. Additional logistical challenges from drilling to procurement of equipment to weather abound.

A review of challenges and advantages encountered to successfully complete work include, regulatory policies that are in development can be challenging to interpret, weather leading to flooding/Health and Safety issues, resourcing, supplies, equipment, accomadation of local customs/religious considerations, technical resource availability and mobility restrictions. Challenges also include importing equipment and local availability/quality, opportunistic theft and lack of environmental constructors. The use and availability of quality affordable labor along with determined problem solving have helped overcome those challenges.

Strategic use of the available resources and ingenuity along with stakeholder engagement overcoming challenges has led to successful environmental outcomes. Learning to work with and around these obstacles provides good lessons that can be applied for similar work in developing countries.
