Exhibit 99.1


    CERTIFICATE PURSUANT TO SECTION 302(a) OF THE SARBANES-OXLEY ACT OF 2002


I, David Rosenberg, certify that:

1.   I have reviewed the Annual Report on Form 10-KSB of Hydro Environmental
     Resources, Inc., as amended by the Amendment No. 1 to Annual Report on Form
     10-KSB (collectively, the "annual report").

2.   Based on my knowledge, the annual 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
     the annual report.

3.   Based on my knowledge, the financial statements, and other financial
     information included in the annual 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 the annual report.

4.   The registrant's other certifying officer and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in the Exchange Act Rules 13a-14 and 15d-14) for the registrant and we
     have:

     a.   Designed such disclosure controls and procedures 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 the annual report is
          being prepared;

     b.   Evaluated the effectiveness of the registrant's disclosure controls
          and procedures as of a date within 90 days prior to the filing date of
          the annual report (the "Evaluation Date"); and

     c.   Presented in the annual report our conclusions about the effectiveness
          of the disclosure controls and procedures based on our evaluation as
          of the Evaluation Date.

5.   The registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation, to the registrant's auditors and the audit
     committee of the registrant's Board of Directors (or persons performing the
     equivalent functions):

     a.   All significant deficiencies in the design or operation of internal
          controls which could adversely affect the registrant's ability to
          record, process, summarize, and report financial data and have
          identified for the registrant's auditors any material weaknesses in
          internal controls; and

     b.   Any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
          controls.

6.   The registrant's other certifying officer and I have indicated in the
     annual report whether or not there were significant changes in internal
     controls or in other factors that could significantly affect internal
     controls subsequent to the date of our most recent evaluation, including
     any corrective actions with regard to significant deficiencies and material
     weaknesses.
