  We present the results of a study of QSO Absorption Line Systems (QSOALSs)
with respect to intrinsic QSO properties using an updated catalog of data in
the literature. We have searched the literature for 6 and 20 cm radio flux
densities and have studied 20 cm maps from the FIRST VLA Survey in order to
compare the absorption properties with radio luminosity, radio spectral index
and radio morphology. This work focuses particularly on the nature of CIV
QSOALSs and their distribution in velocity space in light of intrinsic QSO
properties. We find that the distribution of narrow, CIV absorption systems
with relative velocities exceeding 5000 km/s is dependent not only on the
optical luminosity of the QSOs, but also on the radio luminosity, the radio
spectral index and the radio morphology of the QSOs. These observations are
apparently inconsistent with the hypothesis that these systems are entirely due
to intervening galaxies and it would seem that the contamination of the
intervening systems (from 5000 to 75000 km/s) by those that are intrinsic to
the environment of the QSO is significantly larger than expected. We stress the
need for truly homogeneous and unbiased surveys of QSOALS to confirm these
results from our inhomogeneous data set.
