This question relates to holding times for wastewater samples and that doesn’t apply to the drinking water program or the Safe Drinking Water Act. Please contact your EPA Region for information regarding wastewater testing.
In 40 CFR Part 136, Table II, what is the exact meaning of "do" & "Do" as found in both the preservation techniques and maximum holding time columns?? In the notes "analyze immediately" is defined as within 15 minutes, but what is meant by do?
