Essential Water Sampling Techniques

(Published on 8th April 2016)

NZ Landcare Trust has released a video clip demonstrating basic water sampling techniques for those who would like to take their own samples for water quality monitoring. Craig Simpson Project Coordinator on the Trust's 'Pathway for the Pomahaka' community catchment project, jumps into a pair of gumboots and shows us how it's done.

With a background that includes time working in a water testing laboratory in Dunedin, Craig knows a thing or two about testing. Craig begins by pointing out that water samples should be taken from a location where a waterway discharges from a property. But that's not all, you also need to be mindful of exactly where in the river or stream a sample should be taken... some spots are much better than others.

This video gives specific information such as bottle types for various kinds of test, based on requirements in the Otago region. However the general sampling principles apply to all areas. Thorough cleaning is important unless you are using an already sterile bottle for e-coli testing. Clear labelling of bottles is essential in all circumstances and the general method of approaching the collection site from downstream, is universal.



The Pomahaka Project continues to attract attention, building on the NZ River Story win at last years Morgan Foundation New Zealand River Awards. Craig was recently interviewed for a significant article in the 'Focus on Farming' supplement in the Otago Daily Times.

In the piece Craig explained the importance of collaboration and in particular the value of engaging local communities. The project is all about promoting sustainable land and water management practices, and working directly with farmers and landowners helping them determine the specific issues impacting on this catchment and how best to address them.
