The wavelength coverage provided by EUVE 50-740 Å, comprises nearly the full range of the extreme ultraviolet (EUV). For hot white dwarfs, the EUV data are useful for constraining the temperatures, trace element abundances, and interstellar columns. The objects selected for this initial analysis are three nearby (<60 pc) hot DA white dwarfs, previously observed in the EUV, and apparently possessing pure hydrogen atmospheres. We present our results, of stellar properties and ISM columns for these three white dwarfs, and discuss the implications for the characteristics of the white dwarfs and the state of the local ISM. We also compare our results with those based on previous observations as a check of the relative calibrations of the different instruments.
