Hydrogeology/ Groundwater Specialist Graduate – Environment - Basingstoke, Bristol or Croydon -[...] in London

About Our Team: At AECOM, our water scientists in the Water Environment team work for clients from across the public and private sectors, including UK Water Companies, the Environment Agency, Highways England, Natural England, Water Utilities, Rivers and Wildlife Trusts in the UK, as well as commercial developers and overseas clients. We are also involved in major ongoing projects such as HS2.

The advertised position is to join the Basingstoke, Bristol or Croydon-based team from January 2026 onwards. The role will involve groundwater investigative studies (e.g. baseline studies, conceptual site model preparation, compilation and analysis of water level and water quality data, environmental compliance), groundwater exploration and development field studies (e.g. drilling supervision, borehole specification and design, water level and quality monitoring, step test and pumping test supervision) and groundwater impact assessment studies (e.g. baseline studies, constraint identification, catchment delineation, hydrogeological impact assessment, recommendation of mitigation measures).

Here’s what you’ll do: An integral part of your role will be writing reports and undertaking analysis, interpretation and presentation of data. You’ll also be involved in field work such as water feature surveys, borehole drilling supervision, pumping test supervision and environmental monitoring. Your initial focus on gaining site experience will gradually transition into taking more responsibility for interpreting data and preparing reports.

Your responsibilities will include:

• Site work, including collection of groundwater and surface water data and supervision of borehole drilling and testing.
• Collation, processing and analysis of data into existing and new databases.
• Use of specialist groundwater software, including AquiferWin32.
• Desk study evaluation of project hydrogeology and contributions to factual and assessment reports.
• Preparation of graphical and GIS deliverables.
• Contributing to continued innovation and business development.
• Involvement with and support to the groundwater team and other disciplines such as hydrology, flood, geotechnics, contaminated land and ecology.
