DUNE at LBNF

For our South Dakota neighbors

We think it is important to keep our neighbors informed about the construction of the Long-Baseline Neutrino Facility and the Deep Underground Neutrino Experiment. To ensure that you have the most up-to-date information, we have set up this website with information about LBNF and DUNE.

Community updates

We understand the community’s concerns about dust within Lead, emanating from the Open Cut. We apologize for the significant inconvenience and understand the community’s frustration. We are committed to working to resolve this issue as quickly as possible.

Please do not hesitate to contact us with additional questions at neighbors-sd@fnal.gov.

We encourage our neighbors in Lead to follow us on Twitter (@LBNFacility) or Facebook (Long-Baseline Neutrino Facility). In addition, you may want to subscribe to the free weekly newsletter Deep Thoughts published by Sanford Lab.

Environmental assessment

With the help of a number of technical experts, including independent consultants assisted by Fermilab and Sanford Lab staff, the U.S. Department of Energy prepared an environmental assessment to determine what impacts LBNF and DUNE construction and operation might have on human health and environment.

Public meetings were held on June 17, 2015, in Lead, South Dakota, June 18, 2015, in Rapid City, South Dakota, and June 24, 2015, in Batavia, Illinois.
