Groundwater Services 

Groundwater, as the name implies, is water that is below the ground surface. Groundwater is the primary source of water for more than half of our population and serves as the only water supply for many rural communities. For those who rely on groundwater for water supply, Tetra Tech is there to provide communities with this reliable drinking water source.
