WFD – Initial Characterisation of Groundwater Bodies

As a first step, the Water Policy Framework Regulations require that an ‘initial characterisation’ of the groundwater bodies within the Maltese Water Catchment District be carried out.  The main aim of this initial process is the identification of those bodies of groundwater which are at risk of failing to achieve the Environmental Objectives of the Regulations by 2015.

The Regulations outline that this initial investigation should be based on existing hydrological, geological, pedological, land-use, discharge, abstraction and other data and should identify and outline:

  • the pressures to which the groundwater bodies are likely to be subject including:
    • diffuse sources of pollution;
    • point sources of pollution;
    • abstraction;
    • artificial recharge;
  • the general characteristics of the overlying geological formations and strata in the catchment area from which the groundwater body receives its recharge;
  • those groundwater bodies for which there are directly dependent surface water ecosystems or terrestrial ecosystems

The basic characteristics of each groundwater body in the Maltese Water Catchment District were collated and are presented in the information sheets below.   Further detailed information can be obtained from the document entitled ‘Initial Characterisation of Groundwater Bodies within the Maltese Water Catchment District under the Water Policy Framework Regulations, 2004’.

The ‘bodies of groundwater’ thus identified are as follows:
