@HeatherGranger Can you confirm that the following variables are based on the mean of 1 sample in 1 day (it seems wrong)

HeatherGranger commented 4 years ago

This is correct. As these guidelines are not based on human toxicological information they're not called a maximum acceptable concentration, however it may make more sense to have them as a 'Max' because 'Mean' doesn't really make sense for the 1 sample in 1 day that's taken.

Either way, temperature and turbidity are narrative guidelines, so having a 'Mean' or 'Max' doesn't make for those parameters.

joethorley commented 4 years ago

I'm going to set the Statistic to be maximum in case someone takes multiple samples.
