Observations

  • 28 November 2024

    Lyndhurst Park (downstream of culvert) by Kath Vos

    The Meads is muddy, grass saturated with water from the previous intense rainy days.

  • 26 November 2024

    Upper Costons Northolt Green West by Ben Morris

    improved since this was logged as pollution around a month ago. TW booms in evidence in the stream. Will they be removed?

  • 26 November 2024

    Costons Brook Northolt by Ben Morris

    surprised that this reading gave higher TDS than West tributary, a few metres upstream, despite slightly lower A and P, which you would expect as W trib was source of previous 'spill'

  • 13 November 2024

    Silkstream Park Wetland by Matt Merkies

    High phosphate levels…

  • 13 November 2024

    NHS Blood bank by Matt Merkies

    Noticable that both Ammonia and Phosphate levels much higher downstream from the Tramway Ditch compared to upstream from the Tramway Ditch(Ammonia 0.28ppm, Phosphates 2.05ppm)

  • 13 November 2024

    Montrose Playing Fields Tramshed by Matt Merkies

    Ammonia and Phosphate levels before the (polluted)Tramway Ditch joins the Silkstream. Phosphate levels already high, but not as high as in the Tramway Ditch

  • 13 November 2024

    Greenway Tramway Ditch by Matt Merkies

    High Ammonia and Phosphate levels(max readings on the Hanna checkers), indicating ongoing water pollution. I reported to Thames Water. 2 engineers came to have a look in the evening. I showed them the location. They would check two locations(manholes) upstream and further investigate

  • 13 November 2024

    Kingsbury Brook (East) by Ben Morris

    The stream smelled bad, borne out by the results. Later we recce'd upstream (behind Dors Close) and found and reported a very bad pollution (TW 00857793). (Phosphate device maxed at 2.50, so obviously much higher)

  • 7 November 2024

    Northwick park Brook(Wealdstone Brook?) by Angelique Soon

    River level low, had to take care not to disturb the bottom for the sample Difficult to put exact location on this site. the exact reference is TQ 16878 87350
