Our Soil/Nuestros Suelos is a "do-it-together" approach to identifying toxic soil pollution in places where people live, work, and play. We encourage people anywhere in the world to form community groups, partner with local science teachers or organizations, build low-cost soil screening kits, sample soil, and work together to interpret and act on the results. We provide detailed handbooks (English and Spanish) and video documentation (currently English-only) to help you get started with do-it-together soil testing in your own community.
