    Tottenham Cemetery by Caroline Jepson

    The stream was cloudier than usual, so I have marked it as cloudy, although the colour was still clear, not grey. The depth was twice the average at 20 cm - 35 cm. The levels of ammonia and phosphate were substantially lower than the last couple of readings, perhaps because of the high rainfall in the previous month and the Moselle Brook was twice its normal depth.

    Beech Hall Crescent CSO by Martha Jeffery

    Looks like CSO has discharged recently, probably in the heavy rain last week, as there is more toilet paper on the exit from the CSO pipe than I have seen recently. Picture attached.
