Hydrology and Hydro Geological studies

When undertaking research on a site and its immediate environs, the specialist water environment team at UK Accreditation is particularly interested in the following:

 Presence of watercourses and floodplains e.g. name, location and size of watercourses, existing flood risk;

• Flood and groundwater flow routes e.g. location and importance;
• Groundwater levels including changes in levels and recharge;
• Groundwater vulnerability e.g. location and grade of source protection zone, classification of aquifer vulnerability;
• River and groundwater water supplies (potable, industrial or agricultural) e.g. location and number of abstraction points, volume of water abstracted, use of water;
• Presence of river and groundwater discharge points; e.g. location and number of discharge points, volume of effluent discharged;
• Contribution of discharges to total river flow e.g. proportion of flow made up by effluent at different times of the year;
• Any data pertaining to surface water, groundwater and still waters (lake/pond) quality e.g. existing chemical grade, EC Fishery designation, results of surveys, Invertebrate populations;
• Use of river and still waters (lake/pond) for recreation e.g. presence of facilities and clubs, use for angling (number of clubs/membership)
• Recorded pollution incidents/complaints;
• Recorded flooding incidents;
• Current or historical authorizations, permits or consents;
• Any knowledge of previous investigations or remediation activity relating to land contamination issues; and,
• Special Sites.
