Role description

RWM’s vision is to create a safer future by managing radioactive waste effectively, to protect people and the environment.

RWM’s mission is to deliver a Geological Disposal Facility and provide radioactive waste management solutions. As a wholly owned subsidiary of the NDA, RWM’s programmes of work deliver Government Policy, and NDA Strategy, for radioactive waste management.

The Role

As the Senior Groundwater Chemist you will use your extensive expertise to plan, oversee and deliver the groundwater chemistry research strategy; obtaining solutions in specified areas of expertise to support the needs of internal end-users. These will be key stakeholders across a variety of teams, including Site Evaluation, Site Characterisation, Permitting, Engineering & Design, Environmental Safety Case and the generic and site-specific disposal system. You’ll have overall responsibility for the integration of groundwater chemistry information needs between stakeholders, and the interpretation and evaluation of new and existing groundwater chemistry information to support cross-organisation requirements.

Your experience translating technical challenges into specific knowledge gaps, identifying research needs and objectives, and formulating appropriate research activities will support RWM’s multidisciplinary projects. You will work with a senior team including geological modellers and hydrogeologists, and so an understanding of using and reviewing outputs from numerical groundwater chemistry modelling codes, and collaborating with other subject matter experts, would be beneficial.

This role includes project and work package management activities as well as contract and contractor management.


  • Understanding groundwater chemistry parameters / information requirements needed to support evaluation and characterisation of sites
  • Planning, managing, and delivering surface-based groundwater chemistry investigations
  • Planning and delivering laboratory and URL research and subsequence interpretation and synthesis of results
  • Conceptualisation and representation of groundwater chemistry information, including development of groundwater chemistry tools and techniques needed to support the GDF programme
  • Evaluating the past and future evolution of the site, considering GDF and naturally induced perturbations using numerical representations of groundwater chemistry information
  • Understanding and communicating the output of groundwater chemistry projects to stakeholders, including representing RWM at internal and external fora.
  • Identifying supply chain capability and resources required to deliver groundwater chemistry testing and analysis, including porewaters from clay (and characterisation of evaporite settings), to support the GDF programme
  • Procurement of groundwater chemistry services, including specification of work, assessment of tenders and management of contracts and supply chain

Management (scope, cost, and schedule) of work packages being executed through the supply chain or academia

Skills and Experience

  • MSc or PhD in a related subject, e.g., geochemistry, hydrogeology, environmental sciences, oceanography.
  • Experience of specifying, and using, tools and techniques needed for collection and interpretation of porewaters from clay rocks
  • Experience using natural and additive tracers, and isotope analysis to determine groundwater age / residence time, using results to characterise groundwater end members and conceptualise geochemical site settings
  • Experience of using, and reviewing outputs from, numerical groundwater chemistry modelling codes to evaluate baseline and future groundwater evolution
  • Expertise in planning, managing and delivering the field-based investigations required to collect and analyse groundwater chemistry from deep geological settings / low permeability rocks
  • Experience of collaborating with field staff, numerical modelling experts, supply chain and researchers to deliver integrated site evaluation and characterisation (groundwater) projects
  • Effective communication of technical aspects to both specialist and non-technical audiences
  • Proven ability to influence collaborative and contracted projects to gain the requisite outcomes
