5005 Praxis Practice Test Practice Question
Which of the following is most important to achieving an accurate result when performing a coliform water samples?
Correct Answer: B

Option A, boiling samples, is not necessary for testing coliforms and may alter the sample's integrity. Option C, using samples over 24 hours old, can lead to inaccurate results due to potential bacterial growth or die-off. Option D, while moving water may have different bacterial profiles, does not inherently affect the accuracy of coliform testing compared to equipment sterility.
