Pools - Pool Water Quality
Written Evidence
| What
is to be assessed |
How |
Essential
components and desirable components |
| Verify a pool water testing programme
compliant with NZS 5826:2000 |
Check facility NOP to confirm
presence of a satisfactory testing programme. |
Essential
- NOP must specify:
- Lowest and highest values for the relevant chemical constituents
within the parameters contained in NZS 5826:2000 table 2
- A frequency of testing that meets the minimum set in NZS
5826:2000 table 3 (pool) and 4 (spa)
- The detail and frequency of microbiological tests
- Tests must be scheduled a minimum of monthly
- Tests must include:
- Faecal Coliforms or E. coli
- Staphylococcus aureus
- Pseuduomonas aeruginosa
Desirable
- Chemical tests include a calculation of CAC
- Microbiological tests are conducted fortnightly
- All tests are repeated by an independent quality assured
laboratory fortnightly
|
| Demonstrated ability to meet
NZS 5826:2000 85% of the time |
Examination of water test records
to confirm NZS 5826:2000 met 85% of the time |
Essential
- Two weeks water chemical value tests as specified by the
assessor must confirm the presence of chemicals between
the lowest and highest values set in NZS 5826:2000 85% of
the time
- Four separate sets of microbiological tests as specified
by the assessor must confirm the absence of pathogens 85%
of the time above the highest value set in NZS 5826:2000
table 5 in respect of:
- Faecal Coliforms or E. coli
- Staphylococcus aureus
- Pseuduomonas aeruginosa
- For automated systems see note 3 below
|
Notes:
- If one or more of the tested chemical values are outside the
standard set in 5826 due to a deficiency in the pool design or
plant the assessor may look for evidence that the operator has
taken all reasonable steps to minimise this deficiency. If such
steps are found then the requirements of the AFQMS are deemed
to have been satisfied.
- If microbiological levels are found in the four assessed test
sheets in excess maximums set in 5826 the assessor can examine
further records to evidence compliance 85% of the time.
- If the pool chemical balance is monitored and corrected automatically
appropriate documentation should prove the automated system is
functioning. Documentation should include:
- Two weeks "printouts" or mechanically generated worksheets
- Manual results sheets or checks on machine calibration
- Independent tests
| |
Visual site confirmation of water
quality regime |
Essential
- Visual check of records, testing procedures and pool laboratory
to confirm that written evidence does correspond to what
actually occurs at the facility.
|
| Confirm the operation of a faecal
accident procedure |
Check NOP and confirm the presence
of a faecal accident procedure compliant with NZS 5826:2000
appendix A4(A4.1&A4.2) |
Essential
- Procedure must cover actions in response to
- Faecal solids
- Diarrhoea
- Diarrhoea in a confirmed cryptosporidium outbreak
- Procedure must specify
- Removal of solids and semi-solids (Vacuuming)
- Filtration and turnover
- Evacuation times
- Disinfection
Desirable
That faecal accidents, especially those involving diarrhoea,
are recorded. |
On-site Evidence
| What is to be assessed |
How |
Essential components
and desirable components |
| Faecal accident procedure |
Visual confirmation and staff
questioning |
Essential
- A visual check of records and equipment.
- Questioning of frontline staff to determine that if a
faecal accident occurred it would be dealt with according
to procedure
NOTE:
Every lifeguard is not expected to know the entire procedure.
They must be able to perform the first response to avoid contamination
of pool customers and then know where to access further information
or advice. |
