Healthy, sustainable water benefits both people and the environment.

At SWCA, our water resources services are divided into two main categories: water resources permitting and water as a natural resource.

Driven primarily by the Clean Water Act, our water resources permitting services focus on hydrological phenomena such as the movement and distribution of surface and groundwater. Our experts bring an interdisciplinary approach to help clients navigate water laws at all levels of government.

Approaching water as a natural resource, our scientists conduct thorough investigations of aquatic species and habitats to develop comprehensive management plans, ranging from riparian enhancement and restoration to the recovery of threatened, endangered, and sensitive species.
