Sampling the Well

Prepacked screen monitoring wells can be sampled by several available methods (peristaltic pump, mini-bailer, tubing check valve, mechanical bladder pump, etc.) to obtain high-integrity water quality samples.  These wells also provide accurate water level measurements and can be used as observation wells during aquifer pump tests.

Tubing Check Valves
Choose from a variety of sizes for your specific groundwater sampling needs. Constructed of either stainless steel or PVC. The check valve is fully captured in the body of the valve so you don’t lose the ball!
