(a)
The
in-situ water quality parameters, viz. dissolved oxygen, temperature, salinity,
turbidity and pH, were measured by multi-parameter meters (i.e. Model YSI 6820
CE-C-M-Y) and pH meter (i.e. Thermo Orion 230A+) respectively.
(a)
Digital Differential Global
Positioning Systems (DGPS) were used
to ensure that the correct location was selected prior to sample collection.
(b)
Portable,
battery-operated echo sounders were used for the determination of water depth
at each designated monitoring station.
(c)
All
in-situ measurements were taken at 3 water depths, 1 m
below water surface, mid-depth and 1 m above sea bed, except where the water
depth was less than 6 m, in which case the mid-depth station was omitted.
Should the water depth be less than 3 m, only the mid-depth station was
monitored.
(d)
At each
measurement/sampling depth, two consecutive in-situ monitoring (DO
concentration and saturation, temperature, turbidity, pH, salinity) and water
sample for SS. The probes were retrieved out of the water after the first
measurement and then re-deployed for the second measurement. Where the
difference in the value between the first and second readings of DO or
turbidity parameters was more than 25% of the value of the first reading, the reading
was discarded and further readings were taken.
(e)
Duplicate
samples from each independent sampling event were collected for SS measurement.
Water samples were collected using the water samplers and the samples were
stored in high-density polythene bottles. Water samples collected were
well-mixed in the water sampler prior to pre-rinsing and transferring to sample
bottles. Sample bottles were pre-rinsed with the same water samples. The sample
bottles were then be packed in cool-boxes (cooled at 4oC without
being frozen), and delivered to ALS Technichem (HK) Pty Ltd. for the analysis
of suspended solids concentrations. The laboratory determination work would be
started within 24 hours after collection of the water samples. ALS Technichem (HK) Pty Ltd. is a HOKLAS accredited
laboratory and has comprehensive quality assurance and quality control
programmes. For QA/QC procedures, one duplicate samples of every batch of 20
samples was analyzed.

Other
relevant data were recorded, including monitoring location / position, time,
water depth, tidal stages, weather conditions and any special phenomena or work
underway at the construction site in the field log sheet for information.
(a)
All in
situ monitoring instruments would be calibrated and calibrated by ALS
Technichem (HK) Pty Ltd. before use and at 3-monthly intervals throughout all
stages of the water quality monitoring programme. Calibration details are provided in Appendix E.
(b)
The
dissolved oxygen probe of YSI 6820 was calibrated by wet bulb method. Before
the calibration routine, the sensor for dissolved oxygen was thermally
equilibrated in water-saturated air. Calibration cup is served as a calibration
chamber and it was loosened from airtight condition before it is used for the
calibration. Calibration at ALS Technichem (HK) Pty Ltd. was carried out once
every three months in a water sample with a known concentration of dissolved
oxygen. The sensor was immersed in the water and after thermal equilibration,
the known mg/L value was keyed in and the calibration was carried out
automatically.
