Sandiman Braithe Estuary Partnership Estuary House, Vardenne Quay Braithe BR3 4LN Our reference: KAL-11938/26 Date of report: 4 February 2026 ## 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 Registered in England 2214887 Results relate only to the samples as received
