The Toxic Site Identification Program (TSIP) endeavours to identify and screen contaminated sites in low- and middle-income countries where public health is at risk. The TSIP is not intended to be a comprehensive inventory of such sites, but rather is an effort to begin to understand the scope of the problem. More than 3,100 sites have been identified so far, and more than 1,800 screened on site. These sites alone represent a potential health risk to more than 80 million poor people. However, these 3,000 sites likely represent a small fraction of the overall total. By way of example, over the past twenty years, the United States Environmental Protection Agency (U.S. EPA) has identified tens of thousands of sites in the US alone that require remediation, and its National Priorities List for urgent remediation currently contains more than 1,300 sites. [1] Analysis of the data and trends in the TSIP database indicates that as many as 200 million people may be affected.

In order to carry out site assessments, Pure Earth utilizes a network of national experts in each country to visit and document hazardous waste sites. These national investigators, often from the environment or health departments at a national university, are trained to identify and assess contaminated sites using a rapid assessment tool called the Initial Site Screening (ISS) protocol.  Government representatives also attend the training.  The ISS identifies major elements of a contaminated site, including estimated population at risk, key pollutant information, human exposure pathway data and sampling data. As part of the training, a field visit is made by the group to demonstrate the methodology for assessing the human health impact of toxic sites. Since 2012, GAHP has held training workshops in fourteen countries, and trained nearly 150 investigators and 90 government representatives how to identify and assess toxic sites.
