What you need to take a Drinking Water Sample
The Standard Drinking Water test kit you’ve received with your order will include everything you need to take a drinking water sample. Note that it comes with two different bottles:
The red cap bottle is for the microbiology test
The black cap bottle for the chemistry test.
To make the process as smooth as possible, the kit also includes sampling guidelines and a reception form.
Take a look at our test kit in action ⤵
Process for taking a Drinking Water Sample
Step 1: Turn on tap at an even rate for a minimum of 2 minutes to clear standing water from pipes.
Step 2: Turn off the tap and disinfect it by flaming or if it is fitted with a plastic anti-splash device, disinfect it using a 2% available chlorine solution (such as Milton Fluid).
Step 3: Turn on the tap at an even rate and let the water run down the drain again for 2 to 3 minutes.
Step 4: Place the sterile red-cap bottle under the tap being careful not to touch the inside of the bottle or cap. Fill the bottle leaving a small air gap and replace cap immediately.
Step 5: Proceed to fill the second black-cap chemistry bottle, following the same procedure.
Step 6: Deliver the samples to the lab on the day of sampling under chilled conditions. Use a cool box with ice packs if possible. Samples intended for posting should be sampled as close to posting time as possible to ensure receipt of sample by laboratory so microbiological analysis can be performed within 24 hours of sampling.

Precautions when taking a Drinking Water Sample
Firstly, it’s important to note that microbiology samples must be tested within 24 hours from sampling if you want to receive an accurate result. As a result, it’s important to make sure you can get them to the lab on the day of sampling. If you can’t, delay the sampling to a later date.
Collect the sample from a tap or faucet located at or near the well head or pump house and before the water supply is introduced into any storage tanks or treatment units.
Avoid mixer taps and sample from cold water taps only.
Filling out your Drinking Water Sample Form
It’s also important to fill out the sample reception form so we can properly receive and manage your sample. If you don’t have a form already, log on here and click on “Sample Forms”. Then, download our submission form for liquids.
First of all, we’ll need your contact details. Please include your name, address, mobile phone number, and email address to send you your results. You can also request to have your results sent to you via post.
Mark the date and time sampled, the sampling point e.g. “kitchen sink”, a sample reference of your choosing, the sample matrix as “DW” and the required analysis as a chemistry and microbiology test.
Finally, add your signature to the bottom of the form.
Conclusion
And you’re done! Once your sample is filled and your reception form is complete, you can reseal the envelope and send it via UPS or An Post (location-dependent) to our laboratory in Co. Kerry. Our address is on our contact page here.
