San Francisco Bay Superfund Site Since 1984, SSP&A has directed the investigation and remediation of the 1990 Bay Road Superfund site in East Palo Alto, California.
Piceance Basin, Colorado SSP&A has conducted several field sampling programs, groundwater and gas geochemistry evaluations, and water resource studies related to the develpment of oil and natural gas resources in western Colorado, in addition to other states.
The Columbia Basin Groundwater Management Area SSP&A is assisting a grass-roots organization in developing water resource tools to support assessment of water management alternatives within the 8,000 square mile Columbia River Basalt Group aquifer.
S.S. Papadopulos & Associates was
established in 1979 to provide
and hydrogeology consulting services.
With that cornerstone of expertise, we
have continued to grow and have
developed an internationally recognized
practice in contaminant studies,
remediation, geochemistry, and
surface-water hydrology. Learn More

SSP&A Software Release: mod-PATH3DU
– S.S. Papadopulos & Associates, Inc. is pleased to announce the release of mod-PATH3DU, a particle path and travel-time simulator for structured and unstructured grids. The original PATH3D was one of the first particle tracking programs to support MODFLOW. Since that time, the MODPATH program has become the most widely used particle tracking program for MODFLOW simulators. mod-PATH3DU integrates the capabilities of PATH3D and MODPATH within a single program that is compatible with MODFLOW-2000/2005/USG. Simply register and download the program by following the appropriate links on www.sspa.com/software.
Farvolden Award 2014
– 2014 Farvolden Award
S.S. Papadopulos & Associates, Inc. began supporting the Robert Farvolden Awards in 2011. We awarded 4 scholarships to students for their presentations or posters given at the 2014 National Ground Water Association Summit.
SSP&A Releases GroundWater Desktop
– GroundWater Desktop
Groundwater Desktop (GWD) is a fully 3D interface for visualizing groundwater models and their results. While GWD is flexible and might be used to visualize any model, development to-date has focused on MODFLOW, MODPATH, and MT3D, including the latest unstructured grid capabilities within MODFLOW-USG. GWD enables users to view the model numerical grid, input data such as properties and boundary conditions, and output data including heads, concentration, and pathlines. Models can be examined using cross-sectional, cut-away, and layer "exploded" views.
