Patrick Galvin, P.E.

Patrick Galvin is a Senior Principal Civil Engineer based in California with more than 25 years of experience focused on the design and implementation of site investigations, feasibility studies, and action plans for the remediation of contaminated soils, stormwater runoff, and groundwater.

Railroads formed the industrial backbone during the United States' expansion across North America. But as they evolved, many historic sites along the railways are being redeveloped into live-work-play environments. Pat's work has helped one such site, the Union Pacific Sacramento Rail Yard, begin the transition from Industrial Age artifact to multi-use urban destination. As an engineering task manager, he has led remediation planning for more than 400,000 cubic yards of metals-contaminated soil and contributed to the overall cleanup strategy ahead of development.

Pat develops effective solutions to complex environmental restoration challenges and works with clients and their advocates to secure approval from regulatory agencies for a wide range of public and private sector projects. He has managed assignments for clients throughout the western United States, including railway and mining companies, airport operators, metal recycling operations, ordnance manufacturers, state agencies, and the U.S. Navy. Many of Pat's solutions address impacts from presence of hydrocarbons, heavy metals, pesticides, petroleum products, and chlorinated solvents in soil and groundwater. He specializes in the design and implementation of large-scale remedial investigations and feasibility study (RI/FS) programs; soil and groundwater investigations and restoration plans; and mine waste treatment strategies. He also specializes in the design and implementation of innovative, cost-effective stormwater management solutions and large-scale wastewater treatment facilities. One of Pat's most challenging projects was the construction of a high density sludge treatment plant at California's Leviathan Mine, 7,000 feet above sea level. Today, the facility receives acid mine drainage and neutralizes it with lime prior to discharge to Leviathan Creek. He also has served as a technical specialist on numerous litigation matters, several of which have examined appropriate standards for underground storage tank (UST) removal and the characterization of historic waste fill affecting real estate development.

To advance the state of the practice, Pat is a frequent speaker on the topics of stormwater runoff, wastewater treatment, and the effective removal of outdated USTs. He managed the content development and update to 16 chapters of the Caltrans Hazardous Waste Handbook, a guidance and policy document for hazardous waste staff at the California Department of Transportation.
