Does PVC leach into the sample as well as absorb product being sampled?
No it does not. ESP ran the most extensive spike test available, under method 8260B and 8270, and the results on our PVC where equal to polyethylene, in all areas recognized.
The ClearView PVC bailers are not weighted, how well do they sink?
PVC naturally sinks due to specific gravity in water, but ClearView sink as well if not better than any single weighted bailer on the market. In addition, ESP’s ClearView bailers have no weights, to block the flow of the sample being taken or the purging of the bailer, which results in quicker sampling and purging time.
I have been using a Polyethylene micro bailer, which always seems to be bowed thus causing the bailer to hang up occasionally. Last week I had poly hang up and lost it in the well. Do you make a micro bailer and does it bow, like the ones I have been using?
ESP manufactures a .46″ and .70″ bailer in three and four foot lengths. Our micro bailers are made of the highest quality medical grade PVC. This allows the bailers to maintain its shape, deterring the bailer from bending and hanging up in the well. In addition, Geoprobe has tested ESP micro bailers and stated, “the micro bailers work great and retrieved full samples without hanging up.”
I love to use your Clear-View bailers and have learned that you need to occasional unseat the ball. This is not a huge concern, but do you have any tips on how to keep the ball from doing this?
This is a great question, but you will not have to worry about that anymore. Recently, we changed our mold for the balls, and there is no longer an issue with the ball sticking.
My company has been using all different types of locking plugs over the years. Recently we received a sample of your T- Plugs. How does your plug differ from other plugs?
First of all, our locking I.D. plug truly locks the well; we challenge anyone to prove otherwise. In addition, our plug is manufactured out of a glass-reinforced polymer for additional strength. We incorporated a large wing nut design for ease of installation and removal. The plug is water tight, florescent orange, which helps locate the well, and are priced to you save money.
I have been using your bailer for three years and must say they work very well. My question to you is, do you offer the Clear-View in larger sizes for greater volumes?
Yes we do. We have ClearView Bailers in 1.5” x 4′ and 7′ sizes. Also we have 3.33″ x 3′ that holds up to 5100 mL.
I have a well with about a foot of hydrocarbons to recover. Do you have an inexpensive means of retrieving that product?
Yes, ESP offers a hydrocarbon recovery bailer. We use a polyethylene ball, which floats in water, but sinks in hydrocarbons, which means when you lower the bailer in the well and capture both water and hydrocarbons, the bailer will release the water, but will capture hydrocarbons to be removed.
