| Abstract |
The sampling device selected when obtaining ground water samples can have a significant impact on the representativeness and reproducibility of the sample. The study evaluated several different sampling devices (low speed submersible pump, peristaltic pump, and bladder pump) in two monitoring wells to obtain ground-water samples based on the equilibration of water quality indicator parameters. The indicator parameters were continuously monitored during purging and sampling with all devices and include: turbidity, specific conductance, pH, oxidation-reduction potential, dissolved oxygen, and temperature. Contaminant (chromium and tricholoethylene) concentration levels were also measured for all devices. |
