Tri-Sate Laboratories, Inc. (TSL) was established in October of 1978 initially as a forensic laboratory. Soon it was realized that there was a need for environmental services as such the facilities were expanded to help the industry in the compliance of new federal and state regulations.

TSL expanded to accommodate new services and moved its operation twice since 1981. Current new facility at 2870 Salt-Springs Road, Youngstown, Ohio 44509 was specifically built for TSL in 1993. In the year 2000, TSL acquired Environmental Control Labs (EC Labs) in the Cleveland area. This provided the corporation an additional facility in Northeast Ohio. The number of employees has varied between 30-42. Employees are professionally qualified through experience and academic degrees.
