A search has been made for parity nonconservation in the scattering of 800 MeV polarized protons from an unpolarized water target. The result is for the longitudinal asymmetry, A/sub L/ = +(6.6 +- 3.2) x 10/sup -7/. Control runs with Pb, using a thickness which gave equivalent beam broadening from Coulomb multiple scattering, but a factor of ten less nuclear interactions than the water target, gave A/sub L/ = -(0.5 +- 6.0) x 10/sup -7/.
