Coherent elastic neutrino- and WIMP-nucleus interaction signatures are expected to be quite similar. Next-generation ton-scale dark matter detectors could discover neutrino-nucleus coherent scattering in an underground laboratory. A high intensity pion- and muon- decay-at-rest neutrino source recently proposed for oscillation physics at underground laboratories would provide the neutrinos for these measurements. We show that discovery of this interaction is possible with a 2 ton year exposure of a ton-scale experiment such as GEODM. Furthermore, a dedicated coherent scattering experiment using low-temperature Ge crystals and/or nobel liquids placed close (~10 m) to the neutrino source would see hundreds to thousands of events per year. These higher statistics would enable new limits on non-standard neutrino interactions and searches for sterile neutrinos through short-baseline oscillations. We discuss the potential sensitivity of such an experiment to light sterile neutrino models with Delta m^2 of order 1 eV^2, a region that contains the best-fit 3+1 and 3+2 models to LSND and MiniBooNE data.
