This weeks bumper harvest of e.Coli, from Martlesham Creek, on the beautiful River Deben. The legal limit is nine (9) blue dots, people. Courtesy of @AnglianWater . #Sewage @CleanRiversPGH @sascampaigns @Feargal_Sharkey

There’s a prize for anyone who can count all the dots, because I can’t be bothered now, it’s so appalling. We’ve been testing for six months now, and finding illegal levels all year round.

@Anglianwater operates a sewage treatment plant there….and we get similar readings every week. #CitizenScience is working.

Some background. DEFRA limits attached. Their numbers are per 100ml of sample. So, 1000cfus (colony forming units) per 100ml. We only test 1ml, so the blue dots must be multiplied by 100 to equate. Our sample is incubated at 42c for 24 hours, and the dots then counted.

Here’s a short film we made a few months back. Shows and tells. Feel free to share. fb.watch/e-nwP1w-Mr/ @Feargal_Sharkey @anglianwater #sewage @CleanRiversPGH @sascampaigns

Here’s an ALT TXT version….I’m still learning :-)
