Blacksmith Institute is winding down its cleanup in seven Nigerian villages experiencing the world's worst recorded lead poisoning epidemic. Thanks to a coalition of organizations, a remediation model now exists for widespread replication by the national government.

In summary, achievements have been extraordinary, even heroic, given such difficult circumstances, but much remains to be done. "We have substantially reduced ongoing exposures for over 8,500 people and Doctors Without Borders provided medical treatment for about 1,000 children five years old and under," reported Blacksmith President Richard Fuller.

In addition, the project "has built significant local government remediation capacity," he continued, training more than 200 ministry and local government officials and other personnel, as well as fostered "extraordinary involvement of several hundred villagers in both implementing and sustaining a remedy."

At the request of the government of Zamfara State, a comprehensive, integrated, medical/public health/environmental response is underway. The plan reduces exposure and provides a safe-mining program addressing longer-term issues and re-occurrence prevention.

This project invloved the coordination of many agencies to achieve success. Significant efforts were undertaken by coalition partners throughout every step, most notably TerraGraphics Environmental Engineering, University of Idaho, Doctors Without Borders, the Nigerian Federal Ministries of Environment and Health, Zamfara State Ministries of Environment and Health, Anka and Bukkuyum Emirates and local governments, UN Children's Fund, UN Environmetal Program-Office for the Coordination of Humanitarian Affairs, World Health Organization, and the US and Nigerian Centers for Disease Control.

But the problem is not solved. Major contamination can still be found in Bagega and other villages. More funding is needed and more work will have to be done to insure children are safe.


Never before has there been a lead poisoning epidemic of this magnitude anywhere in the world. People were dying every day. On-going exposure and blood lead absorption were higher than any previously recorded in the international literature. There was a universal lack of international experience and cleanup models to address such an emergency. In a word, the situation was "unprecedented."

Further, affected villages were isolated in a difficult-to-access region of the country with conservative social and religious practices exacerbating exposure and morbidity. Contaminated soils and dusts were the principal sources for exposure in communities where nearly all homes were made of mud, consequently, no relief was available.

"Nevertheless, in just three weeks of collaboration among multiple entities, a remediation protocol was developed and implemented in a manner consistent with village social and technical capabilities," Fuller said. "Greater than 95 percent reductions in soil lead exposure were achieved," he continued, "and treatment initiated for more than 1,000 children and several hundred families in both clinical and out-patient facilities.

"In accomplishing these ends, tremendous health, environmental, technical, engineering, cultural, capacity, political, logistical, safety, funding and implementation challenges were met," Fuller summed up. "Now we have to work to insure the rest of the cleanup can be done, but with local leadership," he added.


A total of 282 residential compounds, 107 exterior areas, and 23 processing ponds have been remediated in five villages. In Bagega, a large landfill has been constructed and prepared for contaminated soils and industrial waste; residential areas, village exteriors, brick-making ponds, and the Bagega industrial site have been assessed; and preliminary design and cost estimates prepared.

Highly contaminated materials from seven ponds in Yarlgama and Dareta--used to make bricks for compound repairs after a particularly damaging rainy season--have been removed.

Male and female advocacy programs have been established to facilitate remediation and support prevention of recontamination, among other community response activities. Villagers are increasingly aware of the dangers of artisanal mining and measures required to protect their families.

The capacity of Zamfara state and local level government to undertake future cleanup has been developed with over 200 ministry, local village, and private personnel trained in appropriate technology. And the international partnership has provided assistance to a new state agency addressing proper mineral processing.
