Preservation & Handling

When you take a water sample to get it tested, the characteristics of the sample need to be maintained for accurate results.

That’s why it’s so important the water sample is taken and stored correctly, and it is supplied to us within the recommended timeframe. Depending on what’s being tested, this could be anywhere from a few hours to several days, a month or even 6 months.

Some of the tests can only be carried out in the field itself by our NATA accredited field officers, who also take samples for some of our regular government and private sector clients (see our water sampling services).

As for taking your own samples, you may wonder how much water you need to collect for the test. What kind of container should you put it in? How long can you keep it? And do you need to refrigerate the sample or not?

While it makes sense to harvest the clean, purified water which falls out of the sky, there are a number of factors which can compromise the quality of this water. The following fact sheet from the NSW Department of Health may be useful for maintaining rainwater tanks

Water, water every where…

Overflowing tanks are often a welcome sight to those who rely on rainwater for their domestic use, especially as it often means no more timed showers! While extra flushing may improve water quality, it is still advisable to have drinking water tested on a regular basis.
