A parity-nonconservation asymmetry has been measured in the total cross section for 6-GeV/c polarized protons on a water target. The asymmetry A/sub L/=(sigma/sub +/-sigma/sub -/)/(sigma/sub +/+sigma/sub -/), defined as the fractional difference of total cross sections for positive- and negative-helicity protons on an unpolarized target, is A/sub L/2.65=(plus-or-minus0.60) x 10/sup -6/. The quoted error includes both statistical and systematic contributions.
