Touchstone

Touchstone recently undertook another water quality check of the Wanaka Spring. All the past tests are available to view on one comparative document as a pdf download via the link on the Touchstone website.

'Water quality is very stable: no meaningful changes in microbiological safety, turbidity, or chemistry.
Slight increase in hardness and nitrate in the third sample, but both remain well within safe limits.
All trace metals remain below detection → no concern for heavy metal contamination.
Overall profile: consistent, clean, moderately hard, slightly alkaline water with very low nutrient loading'.

We often see reference to the water quality from the Wanaka Spring on Lakeside Road. So, Touchstone did a Potable Water test at the end of last month. The Spring water is absolutely excellent, as you all know. But here's confirmation.

The full press release from Touchstone can be found here: https://www.touchstone.org.nz/wanaka-spring along with the testing results.

"After a great deal of community interest in the Wanaka Spring, community focused group Touchstone, decided to fund a Potable Water test of the springs flow for the second time.

The latest test results are much the same as found in 2018. It tests for the presence of bacteria, metals, nitrates and details factors such as hardness and pH. Results are compared to 'Water Services (Drinking Water Standards for New Zealand) Regulations 2022'. These regulations contain “Maximal Allowable Values” that determine if the water quality is fit as a house hold drinking water supply.
​
In the case of the spring ALL the values are very low to non-detectable. Extremely low concentrations of metals and contaminants such as nitrate."

As stated above, the full press release and link to the test results can be further investigated: https://www.touchstone.org.nz/wanaka-spring

Lake Wānaka mapped to better understand natural disaster risks Lake Wānaka has been mapped in intricate detail by scientists to better understand the risk of earthquakes and tsunamis. An active fault was...

And ditto.. as usual for Bremner Bay drain.

While rain at the moment is not uncommon... and run off expected... one of the Roys Bay final bastions of good water quality - Waterfall Creek, is getting hammered by poor soil and land management. Sediment is one of the worst of all contaminants to our waterways. I've contacted ORC but hold little hope to any changes in practice.

For those interested in Tuna, this site provides an interesting story line on our Water Quality.

We have been supporting Wai Wanakas education programmes lately. https://www.facebook.com/851053448427724/posts/2192332767633112/

Our school value of kaitiakitanga means we strive to live sustainably by protecting our unique environment.

As part of this commitment, our Year 8 students are exploring this value and what it means to live it in practice as part of their kaitiakitanga unit of inquiry.

We are so grateful to the team at WAI Wānaka for sharing their knowledge and providing educational resources to support our teachers and students, including:

** providing large water tanks so our students can learn how to test water quality
** donating large interactive display boards
** planning farm visits for later this term.

Thank you to WAI Wānaka for the important work you do in empowering our students to understand their water, their environment and their impact so together we can build healthy ecosystems.
