The study's individual research projects will be published as peer reviewed journal articles or as EPA reports that undergo peer review by external technical experts. The papers will support the draft assessment report on the potential impacts of hydraulic fracturing for oil and gas on drinking water resources. The following is a list of papers published to date. Additional papers will be posted as they are published.
