Suburban Laboratories was founded in 1936. The original lab was located in Cicero, Illinois where it remained for over 30 years.  In 1970 the lab was purchased by three professional engineers; Dr. Fred Gurnham, Robert Konvalinka and Earl Rosenberg. The three owners focused on environmental testing in response to the rise of EPA and the Clean Water Act. In 1971, two of the owners left the business and Ray Thomas, a chemical engineer, became an owner and Technical Director.
