Inertial sampling foot valves are simple and cost-effective tools used for groundwater monitoring and sampling. They consist of a sample tube fitted with a one-way foot valve, which allows water to be drawn up from wells or boreholes. The system operates by oscillating the tubing, either manually or with a powered actuator such as Waterra PP1, causing water to rise and discharge at the surface. These valves are versatile fitting a range of well sizes and capable of deep groundwater sampling. The inertial sampling method is particularly applicable to turbid groundwater conditions.
The foot valves are constructed from stainless steel offering exceptional durability with no risk of damage during use. Stainless steel foot valves can be permanently installed (dedicated) or used portably subject to decontamination between monitoring locations.
