Ammonium and Phosphate were again extremely high, and the samples had to be diluted, but surprisingly this time the source of the pollution was somewhere between YDI 838 (Fort Knox) and YDI 847 Susan St) rather than upstream from YDI 838 as was the case last month.
Samples needed to be diluted 1:1 to get a reading.

The water was fairly clear, but the turbidity reading was affected by particles in the water that looked like a suspension of decomposing vegetable matter.

One area was very scummy [IMG_1258]
