Hydrogeologic Services

Hydrogeology involves understanding the flow of water through aquifers and other shallow porous media. If your project involves groundwater, we can help you. Our staff provides the knowledge and experience for the successful completion of your project.

We are a proven leader in high groundwater analysis and stormwater infiltration modeling using the 3-dimensional, finite-difference modeling program MODFLOW. Stormwater infiltration modeling has become even more critical with the adoption of the 2014 Stormwater Manual for Western Washington.
