Where is the well cap??? How are you ensuring that contaminants aren’t entering the well from the top of the casing when the well is not being sampled/accessed? Why aren’t you wearing nitrile gloves? Regardless of contaminants I the well, your own hands are contaminating the well ESPECIALLY since your sampling for ecoli. You should be disinfecting with alconox or liquinox. Your sounder sensitivity was up way too high. That wasn’t an accurate detection. The case multiplier for a 2” well is 0.16 not 0.17. The equation is simply water column multiplied by cvm (case volume multiplier, or .16 in this case). your purge would be fairly simple if you just used buckets if you must hand bail the water. The sample bottles are now contaminated by your hands which are not covered with sterile gloves. More importantly, where is your water quality meter? How can you be sure that the water is a stable representation of ground water of your not doing continuous monitoring as you purge? You shouldn’t be using your finger to release the water from the bottom of the bailer. Those bailers should come with plastic bottom emptying devices. The string is touching the ground and contaminating the sample.
Thanks for sharing that informative video, which summarized the process, to save time. Excellent illustration.
Very good demonstration
👍
Thank you 👍🏻
Very good! Thank you
Way easier to adopted metric system
That water is contaminated by your hands

I can guarantee this video was off the cuff and was a general demonstration. The sample taken was only for demonstration purposes clearly.
Some much I see that is done wrong
