Abstract
A water sampling assembly for sampling water within a groundwater production well includes a primary pump and a water sampler. The primary pump is positioned within the groundwater production well. Additionally, the primary pump defines at least a portion of an annulus between the primary pump and one of the support casing and the well screen. The water sampler is configured to obtain a plurality of water samples from the groundwater production well without removal of the water sampler from the groundwater production well. Additionally, the water sampling assembly can further include a flow detection assembly that is conjoined with the water sampler within a single jacket to form a conjoined system. The flow detection assembly is configured to detect a flow, i.e. a dynamic flow and/or an ambient flow, of the water within the groundwater production well.
