STATUS/IMPACTS
River status
Overall status
8 River Water Bodies - 6 Moderate, 2 Poor. No lakes
High
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.

PRESSURES/RISKS
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.
Bad
Yet to be determined
75%
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.
SELECTED ACTION PROGRAMME
NB All relevant basic measures, general supplementary measures and SEA mitigation measures
apply
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.
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.
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

FUTURE DEVELOPMENT
Future Pressures
and Developments
OBJECTIVES
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.
