STATUS/IMPACTS

Overall status 30 RWB - 6 Good, 21 Moderate, 3 Poor Status. There are no lakes.

Status elements Q score dictates status in all but 2 monitored WBs, Phys Chemical dictates status for 1 good WB and Hydromorph and Phys Chemical reduce a good WB to moderate (Assaly River at Finoge Bridge). Phys Chemical status high or good elsewhere where monitored. Status was extrapolated for 24 sites. Chemical status is not monitored.

Possible Impacts - EPA Water Quality 2004

Sow -(SE_12_2504 - Status 09 -Moderate based on Q Score); Generally satisfactory ecological condition in 2007 apart from in the upper reaches. Clear signs of nutrient enrichment with abundant macrophyte growth.

Tinnokilla Stream (SE_12_2565 -Status 09 - Moderate); The Tinnokilla stream was in an unsatisfactory ecological condition in 2007. Excavation works in the area suspected.

PRESSURES/RISKS

Nutrient sources 78% of TP is Diffuse, 65% of which is from Agriculture.. 22% of TP comes from WWTP.

Point pressures 14 WWTPs - Ballagh - Village; Ballaghkeen - Hse Est; Ballyhogue; Ballymurn; Bree; Castlebridge WWTP; Crossabeg; Galbally, Wexford; Glenbrien; Murrintown - JP Park; Piercetown WWTP; Tagoat Wexford, Oilgate40 Section 4s – 19 Private Companies, 3 Construction Companies, Lodge, 7 Property Development Companies(1), Golf & Leisure Resort,2 Hotels, Car Sales, Architects, 2 Financial Consultancy, Community Centre, Building Contractor, School.4 IPPC- Metal Manufacturing Company, Engineering Company, Pig Farm, Manufacturers. 2 WTP's - Wexford Treatment Works and Kilmallock Treatment Works.2 EPA Licensed Waste Facilities

2 Section 4s are at risk due to lack of assimilative capacity for BOD and nutrients IPPC – not at risk

Quarries, Mines & Landfills

There are 12 quarries, no mines and 1 landfill but no waterbodies at risk.

Agriculture The majority of the area of the WMU is at risk from Agriculture

On-site systems There are 6579 septic tanks in this WMU, none of them are posing a risk to water quality due to their density, location and unsuitable hydrogeological conditions.

Forestry No waterbodies at risk from forestry

Dangerous substances No waterbodies at risk from Dangerous Substances.

Morphology 1 waterbody at risk due to Channelisation - SE_12_851(River Sow Drainage District, pre 1945 channelisation)

Abstractions 12 abstractions - 3 waterbodies at risk - SE_12_2334, SE_12_2504 and SE_12_3

SELECTED ACTION PROGRAMMENB All relevant basic measures, general supplementary measures and SEA mitigation measures apply

Point Sources

POINT SOURCE:

WWTP – Refer to table below

INDUSTRY – Examine the terms of discharge authorisations to determine whether they require review for the purpose of compliance with water body objectives including protected area objectives and environmental quality standards.

Diffuse Sources

AGRICULTURE – Good Agricultural Practice Regulations and Enforcement.

ON-SITE SYSTEMS - Inspection of on-site systems in at-risk areas to ensure that treatment systems are adequate and maintained to prevent pollution of waters. Consider connection to municipal sewerage systems based on inspections and economic tests.

Other MORPHOLOGY - SE_12_851 will require Channelisation Investigation to

determine impact of drainage works.

OTHER: Protection of drinking water, abstraction control and future licensing.

Measures included in Shellfish Pollution Reduction Programmes under the

Shellfish Directive.

OBJECTIVES

Good status 2015

Protect

3 water bodies

6 water bodies

Alternative Objectives

Extended Deadlines – 21 water bodies with 2021 deadline

New Modifications or Development – none requiring alternative objectives at present.

HMWB/AWB – 1 AWB – Castlebridge Canal

Slaney Estuary Water Management Unit Action Plan

FUTURE DEVELOPMENT

Future Pressures and Developments

Throughout the river basin management cycle future pressures and developments will need to be managed to ensure compliance with the objectives of the Water Framework Directive and the Programme of Measures will need to be developed to ensure issues associated with these new pressures are addressed.
