Fantastic opportunity to survey local river (The Lee) as it passes through arable landscape. Very surprising results with high levels of pollutant scored. Very interesting science lesson as well.

I carried out my monitoring at Dollis Brook in Finchley, a serene and easily accessible section of the stream. The shallow water and good access made it an ideal location for phosphate and nitrogen testing using the Earthwatch kit. I found the process surprisingly easy and, perhaps not so surprisingly, very relaxing — there’s something naturally calming about listening to the water and the birds around you. It’s a great way to engage with your local river, and I would thoroughly recommend trying it yourself. Based on my tests, Dollis Brook appeared to be in fairly good condition, especially considering its urban setting.
