Low Flow Sampling

Low flow purging and sampling involves extracting groundwater at rates comparable to ambient groundwater flow (typically less than 500 ml/min), so that the drawdown of the water level is minimized, and the mixing of stagnant water with water from the screened intake area in a well is reduced. Solinst Bladder Pumps are able to provide flow rates… Continue Reading »
