The assessment and monitoring of groundwater quality has always posed a significant challenge – presenting as it does some special problems. It is by no means a trivial task to know exactly what is going on ‘under-our-feet’, when it comes to status and trends of the chemical quality of groundwater, bearing in mind that the resource:
- can be distributed over tens to hundreds of metres below ground;
- is characterised by flow regime dynamics with a time-scale ranging from a few years to various millennia;
- will often be threatened by a myriad of potentially polluting activities;
- is normally subject to gradual, often insidious, deterioration under the pressure of contaminant loading from the land surface.
Groundwater quality monitoring has been a neglected aspect of overall environmental surveillance in many countries, both within the European Community (EC) and (even more so) beyond. Despite the major importance of groundwater resources for the economical provision of public water-supply and its key role in sustaining some aquatic ecosystems, many governments have been reluctant to face the significant capital costs and operational logistics associated with dedicated, custom-built, monitoring networks, and have thus placed far too much reliance on the monitoring of drinking water receptors (mainly deep high-yielding water wells).
By the end of the course, participants will be able to:
Demonstrate and understanding of:
- the importance of groundwater in society,
- potential impacts on the groundwater resource, and
- the need for groundwater governance.
Grasp the Concepts and Principles underpinning Sustainable Groundwater Governance
Get an approach to conceptual modelling of the flow regime of groundwater bodies in terms of aquifer typologies and visualisation and an introduction to groundwater pollution processes;
Understand the characterisation of groundwater pollutant pressures and behaviour of groundwater contaminants;
Learn groundwater quality standards (in terms of the identification of ‘threshold values’) and the evaluation of groundwater chemical status and trends;
Examine complementary methods and tools for groundwater flow and quality evaluation.
Appreciate the regulatory aspects of groundwater monitoring and be able to correctly interpret groundwater quality monitoring data and results from a regulatory perspective.
Who should attend
The course is designed for groundwater hydrologists, geologists, engineers, chemists, environmental scientists, state/federal regulators, project managers, compliance/regulatory program managers for industry and technical experts.
