Groundwater Monitoring

The term groundwater is used to describe the water that has infiltrated the surface of the earth and formed underground lakes that are referred to as aquifers. Groundwater monitoring consists of taking water quality and water level data, which are plotted and used to monitor changes in trends over time.

Knowing the groundwater level is important for many reasons, such as understanding aquifer levels under normal static and pumping conditions, this will indicate how the levels interacts with local surface water sources, and can help understanding how surface development has impacted the aquifer.

Groundwater monitoring frequently involves testing water within boreholes. Boreholes vary in width and depth, the narrowest being around 2″ in diameter.

Low flow groundwater sampling is a methodology used around the world to simulate ambient flow conditions and take water quality readings. A wide variety of pumps are used to draw a sample from the well such as bladder, inertial or peristaltic pumps and usually combined with a flow controller. Once the sampling methodology for your site has been selected, then choosing the right multi-parameter probe is vital.

The AP-2000 is the first-choice product for regular low flow groundwater sampling work. The probe can fit down a 2” borehole and packs in more sensors than any other probe of this size. The package is combined with sensors which will measure the usual parameters such as pH, ORP, EC, DO and Temperature. Additionally, you can add in any of our ISE sensors, such as Nitrate, or optical sensors such as Turbidity, to suit your project needs.

The following products are ideal for groundwater monitoring projects:
