SAMPLE COLLECTION FORMS

There are several options available to customers who need paperwork and sampling supplies for laboratory analysis with the State Environmental Laboratory.  You may call or email the laboratory so that we may assist in providing paperwork and sampling containers.  It is always best to call the laboratory so that we can collect your customer information, log samples and appropriate or requested tests, provide necessary paperwork and correct sampling materials. Or, you may print the forms below if you do not have time to contact the laboratory before sampling.  The chain of custody is a required sample collection form used to document the customer, sample information like collection location, date and time, and tests requested in addition to custody of the samples.  The customer profile form is used to create new accounts or update accounts on file for customers and to let us know reporting and payment contacts.

 

-NOTICE-

Our Chain of Custody forms have been updated.  Please watch the new videos at the bottom of this page for more information.
