"...The depth at which the disk disappeared from view would then establish the level of turbidity."
"...“Higher turbidity levels,” according to the EPA, “are often associated with higher levels of disease-causing microorganisms such as viruses, parasites and some bacteria.” "
In other words, the clearer water is often a sign of higher microorganism contamination? Quite surprising.

- maxbond 4y agoNo, it's murkier water. The microorganisms cause the light to scatter, giving the water a duller appearance. Similar to how scuffed up glass will appear duller than polished glass. The microorganisms can also have a strong color, the most obvious example being algae. I imagine most of us have seen a bucket of water left in the sun turn green after a couple of days.
