For more than 25 years, Pure Earth and our partners have made significant strides in combating lead and mercury pollution worldwide, improving health and well-being in the communities where we work. Working out of 10 regional offices around the world, Pure Earth’s global team of nearly 100 professionals has completed nearly 340 projects in more than 50 low- and middle-income countries.
