Perceptions of drinking water quality were measured for residents at f
our locations in Western Australia. The total dissolved solid levels f
or the locations varied. Four scales of drinking water satisfaction we
re measured: acceptability of water quality; water quality risk judgme
nt; perception of neighborhood water quality; and attitudes toward flu
oride as an additive. Responses to each of these scales did not appear
to be highly related to total dissolved solids. The relationship betw
een attitudes toward water quality and a variety of psychological, att
itudinal, experiential, and demographic variables was investigated. It
was found that responses to the acceptability of water quality and wa
ter quality risk judgment scales related to perceived credibility of s
ocietal institutions and feelings of control over water quality and en
vironmental problems. For the remaining two scales few significant cor
relations were found. The results support those who advocate localized
information and involvement campaigns on drinking water quality issue
s.
