River Wey

Water low, flowing slowly, green, cloudy. Yellow water lilies, pond skaters and a shoal of tiny fish. Tortoiseshell butterfly on grass by bank.

R Card Used

Water lily leaves. River still low, flowing steadily, green, cloudy.

R-Card showed 1400 CFU/100mL

Water average height, steady, brown, opaque. Male mallard on water and cloud of midges on bank.

River brown, opaque, high, surging with eddies. Conductivity reading did not stabilise, cycling between higher and lower values.

Water brown, opaque, high (site partly flooded), running fast with surging flow. One of the alder trunks at the site had been broken off, presumably during the storm, and I would think had been swept downstream.

Water level and flow average. Water brown and opaque with no odour or foam. E. coli tested using the R cards (first attempt at this method). Colony numbers on the three cards were 43, 57 and 70 (quite variable), giving a final value of 5667 CFU/100 ml, which is higher than normal. Unfortunately I couldn’t compare directly with IDEXX this time as the lab was closed for Christmas.

River high, surging, brown with eddies and spots of foam. Test site partly flooded.

Water brown, opaque, steady flow, average height, some leaves floating downstream. A male and a female mallard swam past the site.
