Burren Water Management Unit Action Plan
River statusSTATUS/IMPACTS
Overall status 8 River Water Bodies - 6 Moderate, 2 Poor. No lakes
Status elements Q score dictates overall status. Phys Chemical was good or high where monitored. Status for 4 moderate and 1 poor WBs are extrapolated. Chemical Status not monitored.
Possible Impacts - EPA Water Quality 2004
Aghalona (SE_14_1296 - Status 2009: Moderate) - Sluggish, lowland stream, excessive weed and silt, distinctly eutrophic. Agriculture suspected.
Burren (SE_14_347 - Status 2009: Moderate & SE_14_1781 - Poor) - Generally over-enriched and eutrophic in 2003, with the exception of uppermost reaches. Slight pollution recorded in mid and lower reaches. Marked deterioration d/s of trout farm at Milltown Bridge. Lower reaches somewhat better but overall considerable room for improvement.
PRESSURES/RISKS
Nutrient sources Almost all TP is diffuse (98%) mainly from Agriculture (60%) and Unsewered Properties (35%)
Point pressures 4 WWTP: Fenagh, Kernanstown, Rathoe, Tinryland.
2 WTP: Raheenleigh, Sion Cross.
4 Section 4s: Manufacturer, Private Company, Developer, Hotel.
Wastewater Treatment Plants (WWTP) and Industrial Discharges
At risk:
Fenagh WWTP - Has recently been upgraded.
Tinryland WWTP
Fish hatchery (SE_14_451) - at risk due to historical deterioration in Q value and currently Q<4 within 3km D/S of outfall.
Rathoe WWTP upgraded according to Local Authority.
Quarries, Mines & Landfills
There are 3 Quarries.
Agriculture 7 WB at risk (SE_14_1546, SE_14_1296, SE_14_1821, SE_14_94, 1SE_14_1781, SE_14_1599, SE_14_451)
On-site systems There are 1875 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 6 WB at risk - SE_14_1546, SE_14_451, SE_14_1296, SE_14_1821, SE_14_941, SE_14_1781. Channelisation, Burren Drainage District (pre 1945)
Abstractions 2 abstractions - 2 WB at risk - SE_14_451, SE_14_347
Other None
SELECTED ACTION PROGRAMMENB All relevant basic measures, general supplementary measures and SEA mitigation measures apply
Point Sources See Point Source Discharge Table for WWTP at risk below.
INDUSTRY: Fish hatchery Section 4 - measures in addition to basic
measures apply.
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.
Other Protection of drinking water, abstraction control and future licensing.
Morphology - Channelisation Investigation to determine impact.
Fenagh WWTP has been recently upgraded. Sewerage Scheme planned for Kernanstown.

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.
OBJECTIVES
Restore/Protect 2015
1 water bodies
Alternative Objectives
Extended Deadlines – 7 water bodies with 2021 deadline
New Modifications or Development – Carlow Main Drainage Scheme in 1 river waterbody (SE_14_1781)
HMWB/AWB - none
