I have been analyzing groundwater around a karst area in the UP that has
Michigan's most significant limestone cave. The purpose is to obtain
evidence for causes of the post-glacial development of the karst system. A
large bog abuts a limestone upland, a likely situation for karst
development, but the process is usually so slow that post-glacial caves
are unusual. The program involved the analysis of water chemistry on
insurgences and resurgences for pH, conductivity, T, Ca, Mg, alkalinity
(HCO3), O2, NO3, and H4SiO4. So far, the chemistry is typical of a
limestone fen, without excess acidity that might help explain the
development of the karst. The puzzle remains.

Bought a used Turner 111 Fluorometer at UM Property Disposal for $10.
It works fine. (Used ones are offered on the web for $2,400.) This
device will be used in dye-tracing karst aquifers in a ongoing project
in Monroe County.
