Question
How should microbiology samples be collected from rivers, lakes, and reservoirs?
Summary
Microbiology sample collection from natural supply
Answer
The following should be considered when collecting samples from rivers, lakes and reservoirs:

•   Unless otherwise specified by the method you are using, when sampling a river, lake, or reservoir, do not sample near the edge or bank.
•   Remove the cap, grasp the sample container near the bottom and plunge the container, mouth down, into the water in order to exclude any surface scum.
•   Fill the container entirely under water by positioning the mouth into the current or, in non-flowing water, by tilting the container slightly and allowing it to fill slowly.
•   Do not rinse the container before use.
•   Label the sample containers immediately and analyze promptly.
