Best Practice Low Flow Methods For High Quality Samples

Low Flow Sampling Since 1996, low flow sampling has become an increasingly approved method for obtaining high quality groundwater samples. Through the work of Puls and Barcelona, the US EPA released standard operating procedures for low flow sampling (EPA/540/S-95/504). Following such guidelines ensures the collection of samples that are representative of actual in-situ conditions. Low… Continue Reading »

Selecting A Solinst Bladder Pump Or Double Valve Pump

Solinst Model 407 Bladder Pumps and Model 408 Double Valve Pumps have a lot in common. Both are pneumatic pumps, both are excellent for providing representative groundwater samples, and both are widely used for low flow and VOC sampling. On the outside, Solinst Bladder Pumps and Double Valve Pumps look almost identical – but internally… Continue Reading »

Deep Groundwater & Dissolved Gas Sampling With Double Valve Pumps

Download Newsletter Sampling groundwater from deep wells is a challenge on its own, but add to that the need for accurate dissolved gas analysis, and the task gets that much harder. Low Flow, Deep Groundwater Sampling HydroTerra, a leading Australian company, and exclusive distributor of Solinst products, provides environmental monitoring solutions. They have developed a… Continue Reading »

Solinst Bladder Pumps Simplify Groundwater Sampling At Ontario Landfill

An environmental monitoring program is an essential part of any successful landfill operation. Monitoring ensures that a landfill is functioning as it should, and that wastes do not migrate off-site or pose potential risks to nearby receptors. Regular environmental reporting ensures that operators comply with the regulations and approvals that govern them. Landfill Technicians Brad… Continue Reading »

Bladder Pumps Exceed Sampling Criteria

A nuclear power facility in England has an extensive groundwater monitoring well network that requires regular sampling. Golder Associates, the project team who developed the network, wished to update their sampling equipment and protocols to improve efficiency, while maintaining accuracy and high safety standards. A set of objectives was defined to help determine the ideal… Continue Reading »

Model 464 Electronic Pump Control Unit

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 »

Freezing Conditions? You Can Still Dedicate Your Bladder Pump

Solinst provides a special “Freeze Protection Assembly” for anyone wishing to dedicate Bladder Pumps in conditions where there is a risk of the sample line freezing. The assembly is simple to install in the field and may be retrofitted with ease to existing Pumps. The assembly can be used with 1.66″ and 1″ Pumps, PVC or stainless… Continue Reading »

Extend Your Pumping Depth

Stainless Steel Bladder Pumps can lift from depths of 500 ft (150 m) below grade, and PVC models from 100 ft (30 m). Samples can be obtained from greater depths using a drop tube assembly. This places the screened filter intake of the pump as deep as necessary to access the sample zone required. Easily installed without tools on existing pumps,… Continue Reading »
