Hi everybody.
Water quality sampling is to be done for 7 wells. The problem is that these wells are currently out of service and they have been out of service for almost a year, but the authorities want to put them back to work and they need to check for the quality of the water.
The question is:
For how long should they "flush" the water out, before taking the samples in order to collect valid samples? Bare in mind that all of the water being pumped out is going to be wasted, and that electricity cost for the pupms is high.
Thank you in advance for your answers.
