Mark Griffiths

Associate Hydrogeologist, Geo-environmental


BSc (Hons), MSc, CGeol, CSci, FGS

Mark is a chartered geologist and chartered scientist with a strong technical background having spent 13 years working on a diverse range of geothermal, geoenvironmental and hydrogeology projects in consultancy and industry.

He joined Hydrock from the multinational food and drink company, Nestlé, where he managed its UK water resources department, leading water stewardship initiatives from sustainable water use to water regeneration projects within the factory catchment areas. For example, working with partners and key stakeholders, Mark was responsible for the delivery of a wetlands restoration of a moor within the Peak District, near Buxton, which will reduce the risk of flooding to the community downstream as well as improving biodiversity and reversing carbon emissions.

Mark also offers a specialist perspective on deep and shallow geothermal energy, an area where he has led research, feasibility studies, and design for various projects across the UK. He was the lead author of a study into the economic decarbonisation opportunities and skills transition that deep geothermal energy can offer the UK. He’s helped local authorities to understand the relevant geothermal solutions within their district by developing geothermal opportunity maps and supporting the technical delivery of ground source heat pump (GSHP) projects.

Mark has also supported universities, hospitals and the private sector with their respective decarbonisation plans, which have considered district heating powered by geothermal energy, delivering feasibility studies and supporting technoeconomic assessments that underpin investment decisions.

Regularly working with developers, contractors and regulators, Mark helps to understand and mitigate the risks associated with contamination, and other geohazards, that threaten to derail construction projects through a combination of geological/hydrogeological modelling to inform robust engineering and contamination assessments.
