Environmental Forensics

Precision Testing Labs (PTLabs), 732-905-5000, provides environmental forensic services including lab analysis testing to age-date petroleum products (diesel, #2 heating oil, and gasoline), data interpretation, and expert court testimony. Besides forensic age-dating, our GC Fingerprint / Fuel Identification services can identify petroleum releases to determine if the fuel is diesel, gasoline, kerosene, used motor oil, or several other commercially available fuels.

Did you know that in many cases, you can determine when a petroleum release began?

Precision Testing Labs is one of the very few labs across the country that provides environmental forensics testing.
