Some of the greatest benefits of no-purge sampling are the low cost to try it and the simplicity of use. There are no large investments in time, energy or materials. Another less-obvious benefit is that using HydraSleeves for groundwater sampling does not have to be a full-time commitment. No-purge sampling does not have to be all or nothing.
Think of it this way - "You can use no-purge sampling in some of the wells all of the time; and you can use no-purge sampling in all of the wells some of the time, but you don't have to use no-purge sampling in all of the wells all of the time." Our apologies to President Lincoln.
Unlike low-flow and volume purging with pumps there are no permanent modifications needed to the well, and there is no impact to the aquifer when using no-purge sampling. The non-committal relationship with no-purge sampling can leave you free to sample with other methods at any time.
Some HydraSleeve users incorporate no-purge sampling for routine groundwater sampling events but will return to pumping when the time comes to recalibrate a model which was set up using volume purging or low flow sampling.
We encourage you to have a non-committal relationship with no-purge sampling. The HydraSleeve can compliment your other groundwater sampling methods. Please consider it a friend - with benefits! Even part-time use of HydraSleeves for your groundwater sampling will result in savings.
If you can't totally curb your purging, ease your way into no-purge sampling by trying the HydraSleeve along with other sampling methods.
