Water Sampling: Shipping of Samples

Once water samples are collected, they must be transported to the laboratory immediately. if you are shipping them directly to a private lab The mode of transportation will depend on the geographic location and maximum allowable time lapse before analysing each parameter. Usually they will require them within 24 hours of the time they were sampled.

Before shipping, always check that all sample bottles recorded on the field sampling sheets have been placed in the cooler or carton. Samples must be shipped in a dark, cool environment using cold packs or melting ice. If ice is used it should be in a sealed plastic bag. The samples should never be allowed to freeze as this can cause irreversible separations and reactions in the water. Shipping labels which clearly identify the source and destination of the samples will increase the transportation efficiency. The procedures stated by the laboratory should be strictly followed.
