How are we sampling?Sample Containers
Order Containers in Advance from Lab
Receive Proper Containers and Quantity!
Ask questions to make sure you receive what you need!
Be Sure to Fill Containers Correctly
Clearly Label Containers Before Sampling
How are we sampling?
Make sure to wear clean powder free gloves while sampling
This not only to keep the sample off you but to keep you out of the sample.
Fill containers completely without over filling them.
Some containers are pre-preserved with acids or bases
The mouth of the bottle should face upstream while sampling.
How are we sampling?Do not disturb the bottom of the area you are sampling.
This will skew your results!After sampling immediately place the sample on ice
This means you must keep ice on hand!If you do not have ice on hand place the sample in the refrigerator and get ice
Where are we sampling?Pipes?Ditches?Manholes?Others?
PipesSafetyAvoid contact with the pipe or other surfaces
DitchesSafetyAvoid contact with the bottom of the sampling locationPlace bottle opening upstream when collecting sample
ManholesSafetyAvoid contacting surfaces in manholePlace the bottles opening upstream when collecting a sample
Other
Who is testing?Make sure the lab is certified to complete the testing.Inform the lab when you will be sending samples in.
This is especially important if you have time sensitive samples

Sampling and Handling Done Right
Proper sampling and handling = accurate data.
Poor sampling and handling will lead to poor data.
Improper sample collection and handling is worse than no sample at all.
Remember: Plan It, Do It, Document It, Review It!
