DISCHARGE SAMPLING
1. Place a suitable drain pan under the WET WELL SAMPLE valve MSD-11 (figure 1, item 1).
WARNING
Sewage is a common mode of transmission for parasitic organisms that may
have the capability of causing communicable diseases. After coming in contact
with sewage or contaminated equipment, be sure to clean yourself with a disin-
fectant soap. Avoid sewage contact with skin abrasions, punctures, cuts, and
other open wounds. Wipe up and clean any spills and/or contaminated equip-
ment using a disinfectant soap. Failure to comply can lead to serious illness.
2. OPEN and CLOSE the WET WELL SAMPLE valve MSD-11 (figure 1, item 1) to flush any contaminants out
of the valve.
3. Fill a suitable sample bottle with effluent from the WET WELL SAMPLE valve MSD-11 (figure 1, item 1). Let
the sample settle for about 15 minutes.
NOTE
A small amount of solids at the bottom of the sample bottle is not uncommon.
4. Check the effluent for color and odor and perform a residual chlorine test (WP 0014 00).
5. If the effluent sample is gray or smells like rotten eggs, perform the air scour and pump out procedure
