  We present the first metal-polluted single white dwarf star identified
through Gaia DR2. GaiaJ1738-0826, selected from color and absolute magnitude
cuts in the Gaia DR2 data, was discovered to have strong Ca~II absorption in
initial spectroscopic characterization at Lick Observatory. Notably,
GaiaJ1738-0826 resembles in many ways the first confirmed metal-polluted
hydrogen atmosphere white dwarf, the DAZ G74-7.
