January Newsletter

Introduction

25 January 2024

Welcome to 2024. Hopefully our readers will be happy to hear that our desire to share knowledge and collaborate with industry continues unabated as we head into the new year. We started the year with a bang, with a really well attended webinar (over 360 registrants) learning about contaminated sites. Many thanks to Dr Victor Kabay.

Whilst on the theme of sharing knowledge, there is a very interesting article in this newsletter which highlights the considerable contribution that groundwater discharges are making to the pollution on Great Barrier Reef. As we build our understanding of these interactions, the need to manage groundwater and groundwater quality, become clear.

Finally, we have shared some exciting news on our progress with our modular telemetered groundwater monitoring systems Stygo. Hot off the production line and destined for a mine site in South Australia. Congratulations to the team on making this vision a reality.

Welcome back to you all!

Lift pump can achieve

Width of bore

Flow rate

Sediments in water

QED Sample Pro – Bladder pump

Up to 50m

4.45cm

Best suited to low-flow purging

Can handle higher sediments

Solinst 407 – Bladder pump

150m below ground level, drop tube assembly can be used to achieve deeper lifts

available in two diameters, 4.22cm and 2.54cm

Best suited to low-flow

Not damaged by operation in sediment laden water

Solinst 408 – Double valve pump

If standing water level is <150m below TOC, theoretically pump lift is unlimited

Available in three diameters, 4.22cm and 0.95cm

Solinst 410 Peristaltic pump – suction lift pump

Up to 6m below ground surface

Pump external, width of tubing 3/8-inch OD

Flow rate can be relatively high, so can be used for low-flow or purging multiple well volumes when depth of well permits

Can handle high sediments due to pump design

Waterra footvalve – Intertia pump

Can provide lifts of 45-60m

Foot valve is small and available in different sizes

Powerpack can be attached for higher flow rates

Can tolerate higher sediments in water

Proactive stainless-steel mega monsoon – submersible centrifugal pump

Lifts up to 50m from ground to water level

Diameter of 4.63cm

Suitable for low-flow and purging multiple well volumes when depth is shallower

Can tolerate higher sediments in water
