Company Audit and inspection
The Company was inspected or audited by the Inspectorate or its appointed consultants on a number of
occasions during 2003. Where relevant, report summaries are available in the ‘Business and Technical’
section of the Inspectorate’s website under ‘Audit and inspection’. Details of the subject areas audited or
inspected are given in the following paragraphs:
Follow up of recommendations made during the 2002 inspections or in connection with water quality incidents
Steps have been taken to implement the majority of the recommendations arising from the 2002 Audit and
inspection process. Further action is to be taken in respect of one recommendation regarding the correct
calculation and reporting of regulatory pesticides results.
Audit trails of selected microbiological test results
Vertical audits were carried out on one test result selected at random from 2003. The Company is being
required to take action on deficiencies identified with ensuring that equipment is calibrated.
Audit trails of selected nonmicrobiological test results
Vertical audits were carried out on two test results selected at random for the period February to May
2003. The Company is being required to take action on deficiencies identified with the instrument records
in respect of one parameter. Deficiencies were also identified in the arrangements for reviewing control
charts but the Inspectorate accepts that Company’s contract laboratory has since introduced new
procedures for such reviews. These will be followed up by the Inspectorate in the next audit.
Incidents
No events were notified by the Company during 2003.
Enforcement action
No enforcement action was considered for the Company as a result of the Inspectorate’s activities
during 2003.
Improvement programmes
The Company has no improvement programmes in place.
