Dear Friends,

We used approximately 12 months of data from the TAMC to establish action
and warning limits for purified water, based on the 2 and 3 sigma concept,
but the results are coming in at a very narrow range.
Standard:100cfu mL
 Action 15 cfu mL
 Alert 8cfu mL
Is it possible to use a wider range or Percentage?


Thanks in advance

Zahiruddeen.
