    UCL East by Izzy Bishop

    Phosphate test was repeated three times due to the initial test having an inprecisely timed reaction time. The value above represents the average reading. The first (not well timed) test read 0.98mg/l. The second read 1.31 mg/l. The third read 1.26 mg/l.

    Lordship Recreation Ground (Downstream) by Caroline Jepson

    These readings are the lowest I have ever recorded. A fortnight ago, Thames Water did fix two blockages in a private line, which their readings confirmed were affecting water in the Moselle coming into Lordship Rec. This incident and action taken by TW was reported to Rebecca at Thames 21. However, there appeared to be an old leak from the Agent B bottle for the ammonia reading, so I wasn't sure how reliable this was, but the subsequent low reading for phosphate backs up an improvement in water quality.
