Conducting Low-Flow Sampling A low-flow sampling procedure starts with purging the water located in the underground aquifer. You’ll have to do it at a rate mimicking the ambient water flow, which is around 0.1 to 0,5L/mm. You’ll also need to choose between manual and automatic pumping. The former method gives you greater control, while the latter is faster. Both methods require close monitoring. After pumping, you’ll need to perform stabilization tests on the water before taking a sample. The key parameters to check include D.O, pH, temperature, and conductivity. The best way to ensure that stabilization is reached is to take readings every three to five minutes. Once you get three readings returning the same results, you can collect the sample.
