It started as a project that investigated “health concerns and data gaps surrounding western PA fracking.” Since then, it’s developed into a nonprofit organization which “supports groups across the United States, addressing pressing 0extraction-related concerns with a lens toward health effects and exposure risks on communities from oil and gas development.” They work to “provide timely and provocative data, ground-breaking analyses, maps, and other visual tools to help advocates, researchers, and the concerned public better understand the harms posed by hydrocarbon extraction.”
