I'll take a stab at these two and see if I can dredge up those
environmental chem and microbiology classes from the dark recesses.
2. Most test kits I have used measure nitrate-nitrogen, ammonia-N, etc.
This tells you the amount of <N> present without all the oxygen or hydrogen
that is present in nitrates, nitrites, and ammonia.
3. Going on memory, total coliform includes bacteria that can live and
reproduce in animal guts and free-living in the environment. Fecal coliform
includes those bacteria that are only able to reproduce in guts. E.coli is
a single species of bacteria that is only able to reproduce in an animal
gut, but can survive in the environment for long periods.
