Our team of experts are central to water resources issues, including water treatment for beneficial use; stormwater permitting, treatment and compliance; groundwater quality, quantity, and cleanup; and fluvial geomorphology and sediment transport analyses.


Catalyst works closely with our clients and public agencies to prepare environmental constraints analyses, National Environmental Policy Act (and state equivalents) analyses, customized planning and compliance documents.  We conduct contamination assessment and cleanup, with a focus on achieving the best use of the land.  


Our work with energy spans its source (oil and gas production, transport, and terminals), generation (wind, hydroelectric, geothermal, and fossil fuels including natural gas, diesel, coal, and nuclear) and transmission. Our team is equipped to handle the environmental and policy aspects of any type of energy project.


Preserving our world’s natural and cultural heritage is critical to who we are as a people. We have worked as part of IUCN’s Geoheritage Specialist Group, and UNESCO’s World Heritage Site review process.  Our World Heritage dream team helps identify and rank potential sites, prepare and manage applications, and provide expert advice and decision making analyses.
