WFD – Pressures and Impacts

Review of the impact of human activity on groundwaters

Introduction

The Water Framework Directive under Article 5 requires Member States to undertake a review of the impact of human activity on the status of groundwaters.  Annex II to the Directive spells out the technical details related to the methodology required for this impact analysis.

As a first step the Directive requires that Member States collect and maintain a register of anthropogenic pressures for each groundwater body which has been identified following the investigations in the ‘Initial Characterization’ phase as being at risk of failing to meet the objectives set in Article 4.  Annex II to the Directive outlines these data requirements as:

  • the location of points in the groundwater body used for the abstraction of water with the exception of:
    • points for the abstraction of water providing less than an average of 10m3 per day, or
    • points for the abstraction of water intended for human consumption providing less than an average of 10m3 per day and serving less than 50 persons.
  • the annual average rates of abstraction from such points;
  • the chemical composition of water abstracted from the groundwater body;
  • the location of points in the groundwater body into which water is directly discharged;
  • the rates of discharge at such points;
  • the chemical composition of discharges to the groundwater body, and
  • land use in the catchment or catchments from which the groundwater body receives its recharge, including pollutant inputs and anthropogenic alterations to the recharge characteristics such as rainwater and run-off diversion through land sealing, artificial recharge, damming or drainage.

The main pressures identified in Annex II of the WFD can thus be summarised as:

  • Point sources of pollution;
  • Diffuse sources of Pollution
  • Changes in water levels and flow caused by abstraction or recharge.

The following sheets summarize the major pressures lying within the surface catchment area of each groundwater body within the Maltese Water Catchment District.
