Duncklee & Dunham was incorporated in 1996 to provide the highest quality and most responsive environmental services a consultant can offer. We strive continuously to meet this objective. Our ability to provide high-quality and responsive services is evidenced by our high percentage of repeat clients. Many of our current clients have relied on our staff since the 1980’s. With a staff of 23 highly experienced and specialized professionals, our Small Business Enterprise has conducted environmental projects in all 50 states for clients that range in size from small, privately owned companies, local municipalities, the State of North Carolina, and law firms to Fortune 500 corporations.

Based in the Raleigh suburb of Cary, North Carolina, Duncklee & Dunham is licensed in North Carolina as a Professional Corporation for the practice of geology by the North Carolina Board for Licensing of Geologists and for the practice of engineering by the North Carolina Board of Examiners for Engineers & Surveyors. We are also a Registered Environmental Consultant (REC) with the Superfund Section, Inactive Hazardous Sites Branch of the North Carolina Department of Environmental Quality (NCDEQ) and employ two Registered Site Managers (RSMs). As an REC, Duncklee & Dunham is certified by NCDEQ to prepare and implement voluntary assessment and remediation contracts.

There are many options when choosing an environmental and engineering consulting firm. The large national and international firms with offices across the globe often primarily focus on ‘making their numbers,’ while lacking any sort of personal touch with their clients. Duncklee & Dunham is not one of those corporations, and our dedicated professionals are tasked with working alongside you to solve your environmental problems first and foremost. If you are searching for a regional firm that is both focused and innovative in meeting the needs of its clients, then that firm is Duncklee & Dunham.


In the 1990’s, our firm was among the first to obtain EPA and state approval of Remedial Action Plans that utilized monitored natural attenuation processes. Today, we use real-time, high-density sampling methods prior to remediation to overcome the inherent complexities caused by contaminant plume and matrix heterogeneity. Simply put, better assessment data lead to lower remediation costs.

Staff Experience and Training

Our staff’s experience assisting clients with federal and state RCRA, CERCLA and environmental compliance requirements is superior. Eight of our 23 employees have over 20 years of experience in the environmental field.  All of our employees have at a minimum a bachelor’s degree in their field of expertise. Weekly staff meetings with this talented team include technical training sessions on innovative technologies, regulatory updates, and health and safety topics. All written documents undergo two levels of peer review by a senior professional and a technical expert prior to issuance. Our open floor plan and integrated office atmosphere facilitates staff collaboration and innovation.

Giving Back to the Community

Our employees are active in state and national professional organizations. We have routinely met with geology and engineering students at universities across North Carolina to discuss geological and engineering careers, donated time and resources to local charities and churches, provided well supplies to construct new water-supply wells in Haiti, coached local youth teams, and organized local, statewide, and professional meetings and conferences for the benefit of the profession. One of our employees formerly served as the Chair of the North Carolina Board for Licensing of Geologists and served on the Planning & Zoning Board for the Town of Cary.
