Stephen BarryUpdate on the Water Framework Directive
Stephen Barry, Environment, Health and Safety Supervisor,
Environment Division,6th September 2016
Water Framework Directive (WFD)
WFD Aims protect/enhance all surface, ground and
coastal waters
achieve "good status" for waters by December 2021 for a number of rivers
manage water bodies based on river basins
involve the public
streamline legislation
Targets
Projected cost of measures
Projected cost of measures by Water Type - National
Projected cost of Measures by Sector -National
Water Framework Directive (WFD)
4 main strategies
Classification
Characterisation Process
Monitoring
River Basin Management Plans
Water Framework Directive
Fingals Rivers
• Of Fingals 23 rivers:17 are classified as risk3 are classified under
review• Pressures include– Sewage treatment– Urban Runoff– Fertiliser Application– Erosion of river banks– Abstraction
What are Fingal Doing
• Improving water infrastructure
• Septic tank inspections• Agriculture inspections• Licencing and
inspections• Surface water
monitoring
Surface Water Monitoring• Operational (Statutory) &
routine monitoring(Non-Statutory) data is available since 2010.
• Monitoring data includes 8 pollutants.
• Assessment of baseline concentrations, current and seasonal trends.
• Identification of pressures using land use data.
Annual Trends
• Why is Phosphorus important?
• Phosphate Sources
• Annual trend across all of Fingal catchment.

Benefits of Analysis• Indicates if pollutant
concentrations are increasing or decreasing
• Provides insights into seasonal emission patterns
• Provides information on the spatial pattern of pollutant concentrations
• Land use characteristics can be examined to identify potential pressures
Meeting Obligations• Monitoring
• Licencing and Enforcement
Identification of substances that are present in the aquatic environment above their natural levels
Identification significant changes or trends that may be evident in water bodies over time
Identification of pressures placed on the aquatic system that may be
resultant of long or short term developments
Focused monitoring programs can help target the source of a pressure
Review of chemical monitoring data can also be used to determine the relative success of applied measures
Use to identifying diffuse, point and episodic pollutant sources
Can be used to inform licencing decisions (e.g. pollutant limits)
More targets enforcement (e.g. determine best investigative measures ranging from septic tank inspections misconnection investigations or agricultural inspections)
Inform on mitigation strategies• Informs on where to
target mitigation measures
• Types of measures to use Floating Treatment

treatmentEnforcementEducational Awareness
Conclusion• Analysis is an important step in
monitoring, enforcement and mitigation
• It can be used to identify sectors which are contributing most to water pollution and therefore inform on policy
• It can be used to assess the impact of the program of measures implemented under the WFD
• It can also be used to identify vulnerable areas within Fingal based on soil type and hydrology
• Resource & Staff efficiency
