What is Hydrogeology
Hydrogeology (hydro- meaning water, and -geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth’s crust (commonly in aquifers).
What does a Hydrogeologist do?
A hydrogeologist makes a significant contribution to the environment by working to better protect and manage groundwater resources.
Hydrogeologists study the distribution, flow and quality of water underground (as opposed to hydrologists who are primarily concerned with surface water).
They interpret technical data and information from maps and historical documents, to build a conceptual model of groundwater flow and quality. They also design and complete investigations, which may include environmental measurement and sampling; and use modelling techniques to enable predictions to be made about future trends and impacts on groundwater flow and quality.
Responsibilities of a Hydrogeologist
- apply a knowledge of fundamental geology to develop an understanding of how rock types and structure in an area impact on groundwater occurrence and movement
- understand and interpret maps, geographical data, historical evidence and models to build up a picture of the groundwater regime and/or land contamination, often based on incomplete information
- use computers to model groundwater flow, chemistry and temperature according to geological formations, surface water flow and man-made influence
- undertake field work and site visits for investigative and monitoring purposes
- design and commission boreholes, and sample and measure groundwater and surface water
- undertake environment impact assessments of groundwater abstraction and management activities
- analyse collected information, to assess and predict the impact of activities such as landfills, construction developments and mining or agriculture, on groundwater quality and resource availability
- liaise with other hydrogeologists, hydrologists, ecologists, engineers and other professionals in related fields
- ensure compliance with environmental legislation and keep up to date with technological and legislative developments
- write reports for clients, which can be understood by people who don’t necessarily have a technical background
- answer technical queries and provide advice to clients and the public in writing and over the telephone
- manage projects and contractors
- work within health and safety guidelines.
Hydrogeologists may be involved in:
- finding new water supplies
- siting new wells
- testing water quality
- protecting water supplies from pollution
- de-contaminating wells.
Verde’s Hydrogeology Expertise
Verde has built a team of water resource assessment specialists focused on delivering quality hydrogeological services to our clients which are led by Donal Hogan, Senior Hydrogeologist who has over 18 years’ experience in hydrogeology related projects. In particular, he has extensive experience in groundwater development assessments to develop a potable and sustainable groundwater resource.
Verde Environmental Consultants provide all aspects of hydrogeological services such as groundwater abstraction feasibility assessments, authorisation of discharges to groundwater technical assessments and water quality/level monitoring.
The development of sustainable groundwater resources is a key element in helping our clients to reduce costs associated with the use of water.
