Notes: 
No obvious source of the nitrogen pollution. I have washed the several times the collection cup in the river before taking the sample. It's in the urban area above Marlow lock. The only thing I can think of is we had a lots of rain in the previous day's, so maybe there's run off of sewage from the plant around wargrave?
