Monitoring well pumps
Monitoring well pumps
(OP)
I'm trying to design a pilot scale P&T system for removal of LNAPL (natural gas liquids). I have several feet of product floating on a confined aquifer. To start with a pump, I've looked at the ones for total fluids recovery and the ones with floating skimmer attachments.
Any recommendations on which type is better? Any specific pros and cons would be appreciated.

What is the depth of the aquifer? Do you have any aquifer parameters (like K) or know what the sustainable pumping rate is? Will the well be drawn down at a moderate pumping rate? When you say confined, what do you mean? If the potentiometric surface is above the top of the aquifer (upward gradient)and well screen, it may affect how liquids enter the well during pumping. In general, it is usually easier to separate liquids in-well and extract as little water as possible - less waste to handle and treat = saves money.
It also seems interesting that you are thinking of a pilot test prior to delineation. What exactly do you hope to learn from the pilot study? If you don't know the extent of contamination, how can you scale up to a full system?
