Profiles
PIEDMONT GEOLOGIC was founded in 1994 as a specialty environmental assessment and remediation firm. Since that time, our staff of scientists, engineers, and technicians have completed hundreds of projects for major petroleum companies, Fortune 500 companies, public agencies, and small and large businesses and industries. Projects have ranged from rapid turn-around property assessments to long-term groundwater remediation efforts.
Our experience-driven, results-oriented approach to environmental solutions serves the interests and successes of our clients’ businesses. We enjoy a high success rate of regulatory approvals and site closures, due to the consistent high quality of our work products and our strong professional ties with regional regulatory personnel.
