How to Collect and Send Water Samples
Samples should be collected at the well head and placed into a clean, single use 1 liter wide-mouth Nalgene (or equivalent) bottle. The bottle should be cleaned simply by allowing the well water to flush out the inside thoroughly and then dumping the contents out prior to filling. It is recommend that the water be allowed to flow out of the source for a period of several minutes prior to filling the bottle. The bottle should be filled to the base of the neck and a small amount of NaOH added prior to tightening the cap securely (we can provide the NaOH). Place a tape seal around the cap/bottle joint to help insure the lack of exchange or loss of CO2 from the water. The bottle should then be labeled with the appropriate sample identification number in indelible ink or on a non-removable tamper proof label.
Samples should be shipped in a sturdy cardboard box, with sufficient packing to insure that the bottles are not damaged in shipment. We recommend that samples be sent by commercial courier or first-class mail. Radiocarbon Sample Data Sheets (click the DATASHEETS button) should be included for each sample along with any required chain of custody or tracking documents that need to be returned.
Upon receipt at the laboratory we will contact you by e-mail or fax to inform you of the samples safe arrival. We will also quote you a delivery date for the reporting of the results (within 6-30 business days of receipt depending on the services requested).
