## 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
