Parameters and drawdown stabilization in slow recharging wells and wells containing a small volume of water.  How do you handle these types of wells to obtain good quality samples?

If you cannot get the water level in the well to stabilize at a pumping rate of around 100 mL per minute, then it's going to be difficult to see indicated parameter stabilization.  Parameter stabilization and drawdown are tied to each other. If it is an extremely low yield well, and you have a very small volume of water to work with, you may end up without sufficient water to actually fill your sample bottles. In this case, it may actually be better to switch away from low-flow purging and sampling, and instead use a passive or no purge type of sampling approach.  It could be minimum purge sampling where you just purge out the volume of the pump and tubing and collect the samples without actually being concerned about drawdown.
