Reduce counting thresholds for your greatest dilution plating in sequence need to be justified. Quantities of colonies over a plate Keep to the Poisson distribution, so the variance with the imply value equals the suggest value of counts.
Limits on the types and quantities of specific natural and inorganic contaminants be sure that the water will incorporate only compact, Secure portions of probably objectionable chemical species. Thus, water pretreatment methods will only be challenged to remove tiny quantities of such likely challenging-to-take out substances. Also, Charge of objectionable chemical contaminants at the supply-water stage removes the necessity to particularly test for some of them (e.g., trihalomethanes and major metals) after the water has become more purified.
