Samples

Step 1:  Complete Chain of Custody

Fill out a chain of custody for the analysis required – Download Chain of Custody.

Step 2:  Collection

Collect the sample based on the following:

a) Chemical Analysis

Coffs Harbour Laboratory requires a one litre clean glass or plastic container filled so that there is no airspace at the top.  Rinse the bottle twice with the water to be tested before filling with the sample.  The Coffs Harbour Laboratory provides appropriate sample containers that are labelled and pre-dosed with preservatives if required.

b) Bacteriological Analysis

For bacteriological analysis the Laboratory requires approximately 200mls of sample in a wide mouth sterile glass or plastic container with an air space of 1 – 2 cm at the top.

c) Soil Analysis

Collect 500g of sample in a plastic zip lock bag and exclude the air.

d) Oyster Analysis

Submit a minimum of 12 unopened oysters for E.coli testing or a 250ml jar of opened oysters for Biotoxin testing. 

Step 3:  Labelling

Samples should be clearly labelled with the name, address and contact phone number of the relevant person.

Step 4: Storage

All samples should be kept cool until delivered to the Laboratory.  This is particularly important for bacteriological samples which should be received by the Laboratory within 24 hours of collection

Step 4: Delivery of samples

Samples should be delivered to the Coffs Harbour Laboratory located at 38 Gordon Street, Coffs Harbour between Monday to Friday from 8am – 4pm.

Coffs Harbour Laboratory staff can collect samples and field tests if required.  Please contact us for more details.
