...always wear gloves, but do not remove the bottle’s lid until it is secured in the orange cuff of the sampling device.
...make sure the rim of the sample bottle is above the cuff edge to allow water to enter the sample bottle directly (even if this means the bottom of the bottle is not touching the bottom of the basket).
...make sure orange cuffs are tightened securely around the bottle(s).
All of the above
For E. coli samples (the 250mL bottle), discard the sample and the bottle. The sample bottle is no longer sterile and cannot be reused.
If you have an extra E. coli sample bottle, use the (previously unopened) spare to attempt the sample collection again.
Because bacteria are so small, an inch of water is all you need to analyze their concentrations.
Both A and B are correct.
Wear reflective or light colored clothing.
Look both ways before crossing the road.
Place a traffic cone alongside the sidewalk/edge of road 20-50 yards up the road.
All of the above
Thunder and lightning
All of the above
Always carry the sampling pole in the fully extended position so you will be more visible to cars.
Look both ways up and down the river, before lowering the sampling basket to avoid hitting rowers or other recreational users of the river.
Be aware of your surroundings when extending or deploying the sampling pole, to avoid hitting power lines, people, and cars.
When loading/unloading the sampling basket, it should be set on the most convenient surface around, even if it doesn’t seem stable.
Collect your E. coli sample
Place both bacteria bottles in the sampling basket/pole at the same time and fill them together.
Place the first E. coli bottle in the sampling basket/pole alone, collect that sample, and then deploy the sampling device for a second time to fill the field duplicate bottle
Take one E. coli sample, then take your temperature and depth readings, and collect the field duplicate E. coli sample at the very end.
...only at sites where the E. coli concentrations are traditionally high.
...only when the person taking the water sample is sick.
...at every site, every time a sample is taken.
...when your hands are cold.
Rinse 3 times with distilled water before loading the sample bottles.
Rinse 3 times in the river before loading the sample bottles
Load your sample bottles, then rinse the sampling device 3 times in distilled water.
Load your sample bottles, then rinse the sampling device 3 times in the river.
...tape the caps down, to make sure they don’t accidentally spill.
...take your temperature reading from the water in the sample bottle before you cap it.
...pick out any large debris (i.e. leaves, twigs) with your fingers.
..tightly secure the lid and immediately put the sample(s) on ice to preserve it.
The time you arrived at the site.
Always 6:00a.m. because that’s when the sample should be taken.
The exact time you actually take your E. coli sample.
The time you turn your samples in at the drop-off site.
Send the Volunteer Coordinator (Cristina) an email telling her you won’t be able to make it.
Nothing, it’s too late anyway.
Call anyone that might be waiting for you (your partner, your drop-off site coordinator, etc), to let them know you're either running late or won't be able to make it that morning.
