Remediation Programs and Projects (

Coming to grips at a national level – Senior officials tasked with putting in place a response to these challenges, at national or sub-national level, need to address a range of institutional and financial issues, as well as building a solid base of data and technical resources. This section presents the main elements that should be put in place for a national (or sub-national) remediation program, together with links to relevant on-going activities.

Implementing Projects – The critical part of any remediation program is the successful implementation of projects, which deal with specific sites or problems. Projects may be large or small and may be simple or complicated and will usually involve both physical works and accompanying interventions in areas of health, education, and pollution control. They require a wide range of skills and expertise, depending on the character of the individual project. The design of interventions may require specific and technical skills and inputs. Management of projects will also require both standard project management skills and also sometimes very specific technology. General resources for remediation project design and technology are provided in the section on Technical Guidance. Included here are advice on specific issues which have arisen on GAHP projects and on practical experience in implementing projects.

How to Mitigate Mercury Pollution in Tanzania

Author: Peter W. U. Appel, Leoncio Na-Oy

Date: May 2013

Description: The environmentally benign borax gold extraction method invented more than thirty years ago in the Philippines and presently used by more than thirty thousand Philippine miners has proved to work on the gold ores in Chunya and Singida gold districts of Tanzania.

Toxic Sites Identification Program – Database

Description: A key step in developing a remediation program is to prepare a working list of sites which are or may be contaminated. The Toxic Sites Identification Program is a worldwide process of helping countries to identify and carry out an initial screening on such sites.

Mercury-Free Gold Extraction Using Borax for Small-Scale Gold Miners

Author: Peter Wiltje Uitterdijk Appel, Leoncio Degay Na-Oy

Date: May 1, 2014

Description: Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health and environmental problems. However, a mercury-free method described below has proved to extract up to twice as much gold without need of investment in new processing equip- ment and without longer processing time. The method has successfully been tested in the Philip- pines, Indonesia, Tanzania, Bolivia and Zimbabwe.

Developing a program for contaminated site management in low and middle income countries

Author: Walter Kovalick and Robert Montgomery

Date: May 2014

Description: This document, prepared for the World Bank’s Latin America and Caribbean Region, summarizes the rationale and the major policy issues involved in creating a contaminated site program, especially for low and middle income countries. It offers alternatives for the design and implementation of the program and it proposes an agenda of actions to be considered.


Management of Brownfields Redevelopment

Author: World Bank

Date: March 2010

Description: This note is addressed to local or regional public authorities responsible for the management of brownfields in the transition economies of Central and Eastern Europe. One of the main goals of the note is to raise awareness of the possibilities of brownfields redevelopment.
