Certificate of analysis

Dear Ms Sandiman

Thank you for the four water samples delivered to this laboratory on 28 January 2026. They were booked
in as batch KAL-11938 and analysed by the methods shown. The results below relate only to the samples
as received.

| Sampling point | Vardenne Channel, station VQ1 |
| --- | --- |
| Date and time of sampling | 27 January 2026, 09:40 |
| Total suspended solids | 41.6 mg/l (method KAL-M04) |
| Chloride | 18,200 mg/l (method KAL-M11) |
| Ammoniacal nitrogen | 0.42 mg/l (method KAL-M12) |
| Dissolved organic carbon | 5.9 mg/l (method KAL-M22) |


The suspended solids figure is higher than those reported for this station in December and January, which
were both below 30 mg/l. The samples were taken on the ebb, two days after the last placement at Kellow
Sands, and the result is consistent with that.

The remaining samples will be held until 4 March 2026 and destroyed after that date unless you ask us to
keep them.

# Yours sincerely

Dr A. J. Prosser
Laboratory Manager
