I have recently begun to trend our environmental monitoring data based on the number of each organism identified as well as the previously documented overall results for a given room. The issue I have run into is how to handle a documented result of TNTC when attempting to analyze the data for individual organisms or even for a specific EM sampling site. I have not been able to determine the best way to show these results graphically. I thought about selecting a number to represent TNTC (say 251 when countable range goes to 250) but I feel that will draw a lot of questions from auditors. Any suggestions or help would be appreciated.
