The last water tests before the chalking have shown that oxygen levels look like they are increasing significantly (8.9 mg/L at 73 % saturation). This is a really good sign and may be linked to the reduction in suspended organic matter in the lake. Ammonia level are still increasing, but Read more…
As last week, no major improvement in conditions to report. Ammonia has increased to 0.46 mg/L, at a pH 7.7 and temperature of 9.0 °C, the rate of increase was lower than previous weeks. Water clarity has continued to improved. Testing next week will be carried out later due to Read more…
Disappointingly, we still don’t have any major improvements in water quality to report. Ammonia level has continued to creep up (0.42 mg/L, pH 7.7) and oxygen levels remain relatively low for the time of year (6.2 mg/L, 54.6 % sat. at 9.7 °C). Water clarity is continuing to improve.
This week’s water testing has shown that ammonia levels are continuing to increase (0.35 mg/L at pH 7.8). Oxygen levels are similar to last week (6.5 mg/L, 60.4 % sat. at 12.5 °C). Water clarity is appearing to improve as the suspended material falls to the lake bed. Increasing level Read more…
The latest water testing results show that oxygen levels are improving slightly (6.5 mg/L, and 59.3 % at 10.4 °C); this is likely to be due to the lower temperatures and bad weather that we have had recently. We have, unfortunately, seen a small up-tick in ammonia levels (now at Read more…
The latest water testing has shown that water conditions have not improved, but have stopped deteriorating as sharply as at the start of October. Ammonia level has risen to 0.25 mg/L, but appears to have stabilised over the last two weeks. Oxygen levels also appear to have stopped declining in Read more…
One of our members has recently contacted Robert Courts MP, Member of Parliament for Witney and West Oxfordshire, about pollution in the Windrush. Here is his response; “Robert wholeheartedly shares your concern about sewage overflows and has been working closely with local campaign groups, such as WASP, to address this Read more…
A petition has been started on the Parliament Petitions Committee website to highlight the problem of sewage pollution in rivers and other water courses. The aim is to encourage the Government to take action on water pollution by water companies and prevent the decline of our rivers. Find out more Read more…
