I am an attorney looking for a lab to test a water sample from my client's well to determine what, if any, chemicals may be present in the water sample. I may be reached at firstname.lastname@example.org.
First of all, you need to know the question to be answered. You must have an hypotesis and then you need analysis of some kind. Was a poisoning case or a suspect from whom of property damage?
First, find a certified laboratory locally. Second, discuss your problem with the Lab Director to determine a course of action. Third, carry though with the recommended analyses for the well constituents that are suspect.
