SLTC is permitted to accept samples from outside the continental US (OCONUS). A copy of the permit must accompany the OCONUS shipments. Request a one-time shipping label (PPQ Form 550 Black/White) from the SLTC Excavation Laboratory before sampling by calling (801)233-5001. Request one label for each package you expect to send.

The minimum sampling size is 2 lbs., which is approximately ⅓ - ½ a one-gallon clear plastic storage bag. Take care not to break up clumps. Obtain a representative sample for each soil layer in the excavation.

Place the sample inside an airtight plastic bag and seal across the length of the opening with moisture resistant tape. Place this bag inside a second airtight plastic bag and again seal across the length of the opening with moisture resistant tape. Place Form OSHA-21 across the seal lengthwise.

A sample that is leaking or has broken in transit, or that is otherwise packaged so it presents a risk of exposure, will be sterilized immediately, discarded, and reported as “Not Analyzed.”
