Yet again, this morning, the Brent is polluted. We were unable to identify the source. We are volunteers. This is not our job. But we will be extremely angry if we don’t see prosecutions for this and other events. Polluters must pay. This has to stop. This was reported to the EA

Not been a great day on the Brent. Meanwhile, in Boundary Stream possible discharge observed. Team on site observed bubbles and a wet wipe.

This was Boundary Stream, Long Wood, tributary of the Brent, back in May ‘22. Teeming with gamarus, I think it’s fair to say this has been the cleanest part of the Lower Brent for many years. Thread…

Wrap up warm today and spare a thought for unit 320, floating in the River Brent and recording an internal temperature of -1.5C

Reunited with an old friend yesterday, Unit 319 broke its moorings in a storm in October and was rediscovered by chance near Gurnell. Looks like it had a good night

Bleachcraft finding its new home on Costons brook

And a warm welcome to Bully Brook, taking our number of monitoring stations to 9. Another 12 planned.

Sighted in the lab...is that a mark 4? With 4G, GPS and needless flashing lights?

And we're at Brentford marina making it 10! It's a gorgeous boat but lets not make 329 jealous

Final 10 devices delivered for deployment. Batch 3 comes with bigger batteries and, like everything else in our lab right now, brick dust.

It's been a close run thing at times but 313 has survived the winter. Operating under its own power in a shady spot since 6th October- we've become weirdly attached to this little box.

RIP bleachcraft. It's not looking like natural causes

Was all a bit of a physical geography #gcse #fieldtrip with Ben from #CURB #CleanUpRiverBrent CURB - CleanUptheRiverBrent #CURB chasing the tributaries flowing into the #RiverBrent, installing monitors & taking water samples to analyse.

Our network continues to operate well and we're keeping an eye on results. At the moment we're not sure if we have funding for this year, but we have plenty of devices still to deploy. I'll be taking a break from the project whilst we welcome our newest team member.

Meanwhile our sister project is monitoring discharges in the Thames Water area botsin.space/@TWDischarges

Two of our Mk4 floating devices launched today. These will share data every 15 minutes to create graphs of conductivity and temperature, both useful indicators of pollution. ⁦River Brent Monitoring Network⁩ ⁦Brent River Park⁩ ⁦Environment AgencySE⁩
