Consultant / Senior - Waste & Contaminant Hydrogeologist

Purpose & Scope of the Role

Tetra Tech is a leading global provider of consulting and engineering services. Our Groundwater & Geothermal Team forms part of a wider geo-environmental and water business and delivers projects for public and private sector clients across the UK and Ireland.
