Images of 16 PQ quasars with z < 0.2 were obtained using the CCD camera at the 2.3 m telescope of Steward Observatory. It is found that about 35% of the quasars have one or more close companions (at r ≤ 100 kpc). The data also suggest that the companion galaxies are almost always redder than the nebulous components of the quasars. This is consistent with previous findings by other investigators that companion galaxies of quasars do not have high level of activity.
