MARK FERMOR BSc MSc CGeol

• Years of Experience: 18
• Areas of Specialisation: Hydrogeological assessment; applied modelling techniques; brownfield development
• Contact Mark Fermor

Mr Fermor is a hydrogeologist with particular expertise in quantitative methods for resource management, contamination assessment and groundwater modelling.  He has practical experience of investigating and remediating a wide range of contamination hazards in soil and groundwater, and in undertaking hydrogeological risk assessments using both qualitative and quantitative methods.  He has considerable experience in the simulation of groundwater flow and contaminant transport, and is able to offer a highly focused and practical approach to the use of modelling techniques for the solution of environmental problems including landfill, mine dewatering, river low flow problems, contaminant plume control and remedial design.  He also provides modelling support and review, and customised training and public access courses and seminars.  Mr Fermor has been responsible for hydrogeological studies involving all major UK aquifers for resource investigations, water supply, contamination assessment and groundwater control.  He has experience performing site assessments for evaluating the migration and impacts of landfill gas and leachate, as well as investigation and remediation of LNAPL and DNAPL compounds associated with petroleum and industrial sites.  Mr Fermor has provided advice regarding regulatory compliance and water quality legislation and standards for numerous industrial and government clients.  He also has extensive experience in providing expert witness services and litigation support and negotiations, and provision of environmental assessments for planning applications and appeals.

ALAN HERBERT BA PhD CGeol

• Years of Experience: 23
• Area of Specialisation: Hydrogeological assessment; application and development of numerical modelling techniques
• Contact Alan Herbert
  
• 
  

Dr Alan Herbert is a hydrogeologist with over 20 years experience of groundwater resource assessment and contaminant transport modelling. He has successfully led projects conducted on all major UK aquifers and dealing with low permeability media.  He has played a leading technical and management role in ESI’s modelling projects for the definition of SPZs, a desk study of the hydrogeology issues associated with low flow problems in the Midlands Region of the Agency, and development of the Environment Agency’s initial methodology for the assessment of the impact of groundwater abstraction on river flows (IGARF). He has led training courses focussed on assessing the impacts of abstractions, soil and groundwater contaminant transport, pumping test interpretation and groundwater modelling.  His experience includes the development and application of customised finite difference and mathematical models to water resources and water quality management issues.  He developed ESI’s Risk Assessment toolkit that has been successfully used to assess the risk to groundwater posed by a wide range of technically challenging landfill assessments for which site specific models were required.  He also has considerable modelling and mathematical expertise applied to groundwater problems through research and lecturing, where the development of models to address transport in the Chalk was a particular interest.

MIKE STREETLY BA MSc CGeol

• Years of Experience: 19
• Areas of Specialisation: Quantitative water resource hydrogeology; EIA; field hydrogeology
• Contact Mike Streetly
  

Mike Streetly is a very experienced hydrogeologist and project director/manager who is well known throughout the industry for his skills and experience in water resource assessment.  He has strong numerical skills which have been applied to solving a wide variety of hydrogeological problems.  He also has extensive practical experience, particularly in the design, installation and operation of hydrometric networks and pumping tests.  He is a regular contributor to professional conferences and has published papers on a variety of topics.  He has served as a member of the committee of the Hydrogeological Group of the Geological Society and is currently on the Editorial Committee of the Quarterly Journal of Engineering Geology and Hydrogeology.  During his professional career Mike has been responsible for water resource studies in all the major UK aquifers.  This includes a substantial number of regional groundwater model studies for the Environment Agency as well as more site specific studies for most of the major water companies.  He has also had extensive experience of developing a clear understanding of hydrogeological conditions in drift deposits and minor aquifers through his work for the extractive industry.  He has been project manager for many hydrogeological impact assessments for the extractive industry including several of the largest limestone quarries in the UK.  He has acted as project manager for a similar number of private water supply schemes.  He also has acted as an expert witness in matters related to natural mineral waters.

ROB SEARS BA MSc CGeol

• Years of Experience: 15
• Areas of Specialisation: Landfill investigation; numerical modelling, data management and risk assessment
• Contact Rob Sears

Mr Sears is a hydrogeologist with a background in all aspects of hydrogeological site investigation, including the drilling and completing of boreholes, sampling, data management and data interpretation.  He has particular skills in groundwater modelling and contamination assessments, which are used as the basis for risk assessment studies.  These include the development and application of complex recharge models to simulate hydrological processes above the water table and complex groundwater flow models involving stream – groundwater interaction below the water table.  He is also very experienced in data management and was responsible for designing the Oracle database structure and data management quality system used to store and maintain all data relating to the BNFL Drigg site investigation programme.  Mr Sears has worked previously in the radioactive waste industry where he has been responsible for the conceptualisation of hydrogeological models and numerical simulations that have been used in support of authorisations by the Environment Agency.

HANNAH FRASER BA MSc FGS

• Years of Experience: 10
• Areas of Specialisation: Contaminated land assessment and remediation; risk assessment
• Contact Hannah Fraser
  

Hannah Fraser is an experienced hydrogeologist with a broad range of experience in Contaminated Land assessment and remediation, human health and environmental risk assessment, mining and quarrying hydrogeology, and groundwater resource assessment and development.  She has worked nationally and internationally on a variety of projects, with her technical roles including project design and management, contaminated land assessment, remediation design and implementation, regulatory liaison and negotiation, groundwater and risk assessment modelling, fieldwork and drilling supervision, groundwater resource assessment and development. She has extensive experience of investigation of residential properties for the purpose of human health risk assessment, and has been involved in the design and implementation of both the investigation and remediation of such sites.
