Using the HST/ACS imaging of the Extended Groth Strip, we have found two new strong gravitational lenses, bringing the total known in that field up to three. We fit detailed lens models to these lenses. We also report on four additional as-yet unconfirmed gravitational lens candidates. This field, studied panchromatically by the AEGIS Collaboration, also has nearly complete spectroscopy to redshifts beyond 1 from the DEEP2 Survey. Using the three-dimensional view of the Universe towards these lenses, then, we study both the local environment, and the effect of the all galaxies along these lines of sight. We find that lenses live in a broad variety of environment, and that dark matter from large scale structure is required for consistency with the gravitational lens model results.
