RTD is an employee-owned environmental consulting firm of highly-skilled, diversely experienced professionals dedicated to providing excellent service and practical solutions for our clients. We are led by Howard E. Whitney, principal CEO and co-founder of RTD, and a California professional geologist and certified hydrogeologist, with groundwater consulting experience since 1983. Professional and technical field staff are OSHA health and safety trained for hazardous waste operations and are experienced in safely providing exceptional services.

RTD also teams with expert environmental specialists for particular job requirements. These associated firms provide civil, chemical and geotechnical engineering, geochemistry, ecology, industrial hygiene, and toxicology services. Most technical field work is performed by our staff; however, certain activities are conducted by subcontractors, including laboratory, drilling, surveying, construction, electrical, excavation, plumbing, and waste removal. Subcontractors are selected that meet our high standards for experience, professionalism, and certifications.
