Hi all,
I've been surveying, and doing some water quality work, on some of <"Bristol's pond and rivers"> over the last couple of weeks.
I had an interesting one today. I won't tell you the location, or context, but it was a pond and the water sample had a dissolved oxygen level of 180% (~20oC, 18mg/L DO) and a pH value of pH 10.5.
Question is a really simple one: What did the pond look like?
Any suggestions welcomed, and I'll post the answer picture at some point.
cheers Darrel
