Hydrogeology is the specialism within geology concerned with underground water, its movement, behaviour and quality.

Geologists in the hydrogeology sector are involved in exploration for water resources, their management and sustainable production. Some are employed by water companies whilst others may have roles in engineering or environmental consultancy firms. The work of a hydrogeologist may include ground investigation, borehole construction, collecting data in the field and developing conceptual site models.

There are a wide range of contexts in which hydrogeologists work and specialise including groundwater resource and quality assessment, well design, construction and operation, pollution, contaminated land and groundwater remediation. Many also carry out environmental impact assessments associated with groundwater abstractions, oil and gasmining and quarrying, landfills, ground source heating, geothermal energy and construction works. Some work to understand and mitigate natural hazards (such as groundwater flooding) while a smaller number work in academia or nature conservation.

Geoscience Areas

Hydrogeologists draw from their knowledge of, and potentially specialise, in disciplines such as:
They may also use related sciences such as ecology and hydrology. 

Other skills such as effective communication and report writing, and the ability to evaluate the reliability of data from different sources, are also important.

How do I get here?

A postgraduate qualification is essential. The majority of hydrogeologists have a first degree in geoscience and then an MSc in hydrogeology or a PhD on a groundwater-based topic. However, some undertake postgraduate study in hydrogeology following first degrees in mathematics, engineering or a non-geological science.
