Proper Lab Analysis Documentation
Please NOTe
samples collected for in-house testing
(to monitor day-to-day treatment
system operations) do not have to be
analyzed using approved wastewater
test methods, even if you are asked to
submit these results to your inspector.
This includes samples collected for
other purposes (research, production
QC/Qa, etc.)
