Abstract
Provided are low flow groundwater fluid sampling systems and related methods of collecting fluid samples, including a low flow pump, flow cell, waste container and a communication device in communication with those components. In this manner, the low flow pump may be controlled to ensure a desired constant flow-rate is achieved, and a remote operator may monitor the status of fluid being pumped to the flow cell with the communication device, such as with a portable electronic device, including a smart phone. The system may alert the operator that fluid is ready to be collected for sampling, including at an off-site laboratory. Particularly useful applications are for monitoring groundwater quality and contamination.
