New North Carolina Location! For 27 years, Emerald has successfully provided Environmental, Waste Management, and Industrial Hygiene services in the Great Lakes region while operating exclusively out of northeastern Ohio. Another service center, however, was needed to support our clientele with facilities and operations in the Mid-Atlantic and Southern regions of the United States. In addition to our geographic growth, we have also expanded our business lines over the past five years to provide inspection, maintenance, and repair services for Stormwater, as well as UST, system owners. Emerald has developed innovative and sustainable solutions to address regulatory compliance issues for the owners of these systems, especially as they pertain to retail petroleum and convenience stores. Thank you for your continued support!
