When to Submit

Best time: April - October. 

Submissions are highly discouraged during peak season (December 1 - March 31). However, any received during this time will be processed as lab time permits, but may have a significantly longer turnaround time.

Required Forms

• Complete the Sample Submission Form for Heavy Metals and submit it with the samples.
• Samples will not be accepted without the printed submission form. 
• A valid email address is required for report delivery. Physical copies of reports are not available by mail.

How to package

• Package soil sample boxes tightly within a cardboard shipping container to lessen the potential of damage during shipping.
• Do not tape the sample boxes.
• Use only NCDA&CS soil sample boxes. DO NOT ship samples in paper envelopes or plastic bags.
• Make sure your completed submission form is included with your samples.
• Label "Heavy Metals Testing" on the outside of the shipping box.
