I, Brian H. McInerney, certify that:

1)       I have  reviewed  this  quarterly  report on Form 10-Q of Glacier Water
         Services, Inc.;

2)       Based  on my  knowledge,  this  report  does  not  contain  any  untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances  under which
         such  statements  were made, not misleading  with respect to the period
         covered by this report;

3)       Based on my knowledge,  the financial  statements,  and other financial
         information  included in this  report,  fairly  present in all material
         respects the financial condition,  results of operations and cash flows
         of the registrant as of, and for, the periods presented in this report;

4)       The  registrant's  other  certifying  officer and I are responsible for
         establishing  and  maintaining  disclosure  controls and procedures (as
         defined in Exchange Act Rules  13a-15(e)  and  15d-15(e))  and internal
         control  over  financial  reporting  (as defined in Exchange  Act Rules
         13a-15(f) and 15d-15(f)) for the registrant and have:

          a)   designed such disclosure controls and procedures,  or caused such
               disclosure  controls  and  procedures  to be  designed  under our
               supervision,  to ensure that material information relating to the
               registrant including its consolidated subsidiaries, is made known
               to us by others within those  entities,  particularly  during the
               period in which this quarterly report is being prepared;

          b)   designed  such  internal  control over  financial  reporting,  or
               caused such  internal  control  over  financial  reporting  to be
               designed under our supervision,  to provide reasonable  assurance
               regarding  the   reliability  of  financial   reporting  and  the
               preparation  of financial  statements  for  external  purposes in
               accordance with generally acceptable accounting principles;

          c)   evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls  and   procedures  and  presented  in  this  report  our
               conclusions  about the  effectiveness of the disclosure  controls
               and  procedures,  as of the  end of the  period  covered  by this
               report based on such evaluation; and

          d)   disclosed in this report any changes in the registrant's internal
               control  over  financial   reporting  that  occurred  during  the
               registrant's most recent quarter that has materially affected, or
               is  reasonably  likely to  materially  affect,  the  registrant's
               internal control over financial reporting; and

5)       The registrant's other certifying  officer and I have disclosed,  based
         on our most  recent  evaluation  of  internal  control  over  financial
         reporting,  to the  registrant's  auditors  and audit  committee of the
         registrant's  board of directors (or persons  performing the equivalent
         functions):

          a)   all significant  deficiencies and material weakness in the design
               or operation of internal controls over financial  reporting which
               are  reasonably  likely  to  adversely  affect  the  registrant's
               ability  to  record,  process,  summarize  and  report  financial
               information; and

          b)   any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
               internal control over financial reporting.
