FracTracker, the project, was originally developed to investigate health concerns and data gaps surrounding western PA fracking. Today, as a non-profit organization, FracTracker Alliance supports groups across the United States, addressing pressing extraction-related concerns with a lens toward health effects and exposure risks on communities from oil and gas development. We 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.
