S.S. Papadopulos and Associates, Inc. (SSP&A) was established in 1979 to provide professional groundwater and hydrogeology consulting services.  With that cornerstone of expertise, we have continued to grow and have developed a recognized practice in contaminant studies, environmental engineering, remediation, geochemistry, and surface-water hydrology.
In addition to addressing site-specific water resource and contamination projects, SSP&A staff have been retained as expert witnesses and technical experts in high-profile judicial, administrative, and regulatory forums.  Several SSP&A staff have been appointed to prestigious federal committees investigating current issues in contamination and remediation and defining the role of the science in addressing the nation's environmental problems.
SSP&A's corporate office is located in Bethesda, Maryland. Regional offices are located in Boulder, Colorado; San Francisco, California; Portland, Oregon; Austin, Texas; and Montreal and Waterloo, Canada. Our offices are closely affiliated, and staff members work together to provide the optimum combination of technical expertise and experience to deliver innovate and effective solutions for our clients.
