Good Laboratories for Measuring Lead, Cadmium and Arsenic in Soils


These labs passed our lab quality assessment. The assessment procedure is outlined here. Other laboratories may be reviewed in future. The labs will accept soil samples sent through the mail, the least expensive way to send them. This will not affect the results, but such samples will not be legal samples because a proper chain of custody and sample storage conditions are not maintained. If you want to follow full chain of custody and and sample storage conditions, contact the lab for more information.

Contact the lab you select before sending any samples.
