Water Framework Directive Monitoring Implications for Local Authorities
Seán Ó Breasail Project Co-ordinator South Western River Basin District WSNTG Annual Conference September 2007
Water Framework Directive
Maintain “high status” of waters where it exists, preventing any deterioration in the existing status of waters and achieving at least “good status” in all waters by 2015.
Manage water bodies in a way that protects ecosystems and habitats.
Involve stakeholders – community groups, public representatives, state agencies, trade organisations, and the general public.
Water Framework Directive
For surface waters • “high ecological status” means that “quality elements show little or no effects of human activity compared to undisturbed conditions” • “good ecological status” means “quality elements show only slight changes caused by human activity compared to undisturbed conditions”.
Water Framework Directive
• For groundwater good status must be achieved for quantity and water chemistry .
Good surface water status equals good ecological status and good chemical status HUMAN IMPACT pass WFD fail WFD Any WFD Monitoring site with Q < 4 requires investigative monitoring

Water Framework Directive – Article 8 Monitoring of surface water status, groundwater status and protected areas
Member States shall ensure the establishment of programmes for the monitoring of water status in order to establish a coherent and comprehensive overview of water status within each river basin district:
Water Framework Directive – Article 8
- for surface waters such programmes shall cover: the
volume and level or rate of flow
to the extent relevant for ecological and chemical status - the
ecological and chemical status
Water Framework Directive – Article 8
- for groundwaters such programmes shall cover monitoring of the chemical and quantitative status,
Water Framework Directive – Article 8
- for protected areas the above programmes shall be supplemented by those specifications contained in Community legislation under which the individual protected areas have been established.
Water Framework Directive – Article 8
Protected areas include areas designated for
(i) abstraction of water
human consumption,
(ii)
protection of economically significant aquatic species
, e.g. shellfish, (iii)
recreational waters,
bathing waters, (iv)
nutrient-sensitive areas,
(v) protection of habitats or species
Water Framework Directive – Article 8 Monitoring of surface water status, groundwater status and protected areas Monitoring programme started on 22 nd December 2006

Surveillance monitoring
Selection of sites and the wide range of parameters were determined by the text of the WFD. Biological quality elements General physico-chemical (12 times / year) Priority substances (12 times / year for one year in the cycle) EPA undertaking surveillance monitoring
Operational monitoring
Monitoring to check effectiveness of Programmes of Measures (PoMs) Point Source Measures Diffuse Source Measures Measures to protect High and Good Status Measures to bring rivers back to Good Status
Operational monitoring
Rivers ~ 2,500 sites ~ 1,300 biology only sites ~ 300 physico-chemical only ~ 900 physico-chemical and biological Lakes 226 sites

• • Operational monitoring sites • Surveillance monitoring sites Pre WFD physico-chemical sites
Investigative monitoring
Pollution Incidents Rolling catchment programmes Biological risk assessment (SSRS) Physico-chemical sampling EPA advises that one quarter of physico-chemical resources should be assigned to this programme
Investigative monitoring
Electronic networks to look at temporal variations in e.g. conductivity, turbidity, dissolved oxygen Remote sensing using aerial photography or satellite images
Investigative monitoring
Likely level of investigative monitoring required There are approximately 2,700 WFD monitoring sites nationally located on main-stem rivers 1,015 sites designated < “good status” ~230 impacted by diffuse pollution, ~260 impacted by point sources remainder no definite cause identified.
Investigative monitoring
Case Study – Cork County Council – rivers and lakes
76 sites were identified as being < “good status” 28 impacted by point sources 26 impacted by diffuse pollution 22 had mixed sources of pollution.
Investigative monitoring
Investigative monitoring required upstream of diffuse and mixed sources of pollution Investigative monitoring also required upstream of sites impacted by multiple point sources
Investigative monitoring
Next steps following identification of areas requiring investigative monitoring Undertake detailed desk study; gather data on water quality, farm surveys, IPPCs, Section 4s, planning files, etc.
Using GIS, identify the probable source(s) of pollution.
Develop micro-projects for each site, i.e. identify locations to be sampled (physico chemical / biological) upstream of the problematic site.
Investigative monitoring
• It was estimated, that for each problematic site, there would be a need to locate 10 I.M. sites upstream.
• IM sites for diffuse pressures require biological monitoring (one visit to each of 10 sites required) • IM sites for point sources and mixed pressures require physico-chemical monitoring, up to 8 site visits to get meaningful data.
Investigative monitoring
It was calculated that approximately 4,200 (some biological and some physico-chemical) samples would be required as part of the investigative monitoring programme. These are to be spread out over the 3 year RBMP period.
Small Streams Risk Score
SSRS was developed by EPA and WRBD as a quick biological tool. It uses invertebrates to make a rapid assessment in the field. It is not a method of determining water status.
Investigative monitoring
1,400 samples or SSRS tests / year Sampling time – 580 hours Analytical time – 1,300 hours Management & reporting time – 680 hours Staff costs Mileage – 10,000 miles = Consumables
Total Annual Cost
€73,200 €12,100 €17,700
€103,000

Summary
Monitoring will be more effective.
Significant demand on local resources RBD projects can assist investigative monitoring programmes.
