Kilfenora Tier 3 Assessment Final.docx 1 26.06.2014
EXECUTIVE SUMMARY
Geosyntec Consultants Ltd (Geosyntec) was commissioned by Irish Water to complete a Tier 3 risk assessment of a municipal Waste Water Treatment Plant (WWTP) effluent discharge to groundwater located in Kilfenora, Co Clare. The Kilfenora WWTP is understood to provide secondary treatment (activated sludge unit) for sewage form a population equivalent of 280. The discharge location is to a stream at the point where it enters the Ballybreen swallow hole, located in the townland of Ballybreen approximately 600m to the west of Kilfenora village. As such it is deemed to be a direct discharge to groundwater.
Clare County Council originally applied for a discharge certificate in 2009. This process is now being managed by Irish Water. As part of the application the EPA requested that a Tier 3 risk assessment for the site was completed in accordance with the 2011 EPA “Guidance on the Authorisation of Discharges to Groundwater” and the EPA (2014) “Guidance on the Authorisation of Direct Discharges to Groundwater”. Geosyntec consider that the current discharge is a ‘direct discharge’ to groundwater in accordance with the EPA guidance and the groundwater regulations underpinning this guidance. However, we understand that Irish Water have commissioned consulting engineers to design an upgrade to the WWTP at Kilfenora to include an appropriately engineered percolation system or other measures designed to reduce the pollutant loading from the discharge. This will have the effect of ending the ‘direct discharge’ to groundwater and improve the final effluent quality. Geosyntec have therefore completed this assessment on the assumption that the WWTP is in the process of being upgraded.
The regional geology is dominated by carboniferous limestone. This limestone is karstified meaning large open conduits exist in the limestone which can transport groundwater great distances over relatively short periods of time. This rapid migration of groundwater (and dissolved or suspended contaminants) is such that beyond dilution and dispersion, little or no contaminant attenuation occurs within the groundwater system between a pollutant source and a receptor.
Tracer studies of the Ballybreen swallow hole in 2001 and 2012 confirmed that the water sinking at Ballybreen is primarily connected to a series of springs approximately 6.5km to the south east of Ballybreen (Figure 1). These springs form the head waters of the River Fergus. Under high flow conditions a component of the flow was also demonstrated to impact on the Cloongarve stream around 1.6km to the west. The 2012 tracer study also demonstrated connection to a series of domestic water supply wells to the east of Kilfenora. The tracer studies suggest significant conduit flow from the swallow hole to the springs with a lateral diffuse connection to wells to the east (Figure 2).
The main contaminants of potential concern (COPC) from the discharge at Ballybreen are considered to be microbial pathogens, nitrogen and phosphorous compounds.
It is understood that all of the households using wells identified as being at risk of contamination by the Kilfenora WWTP discharge in the 2012 tracer study were offered a mains water connection by Clare County Council. Whilst monitoring of these abstraction wells did provide evidence of impacts to groundwater quality, a

material impact on the water quality in the River Fergus was not evident at Poplar Bridge, i.e. this stretch has good water quality status with no exceedences of the environmental quality standards for surface water in 2013. This is likely to be due to the significant degree of dilution afforded by other inputs to the river.
A conceptual Site Model (CSM) was constructed for the site that presents the source, pathway and receptor information for the study area. This information is also presented schematically by Figures 2 and 4. A key element of any risk assessment is the identification and characterisation of the source-pathway–receptor relationships that make up the CSM.
The tracer studies have confirmed that there are direct connections from the discharge at the Ballybreen swallow hole to both the private water supplies wells in the study area and the River Fergus i.e. viable S-P-R linkages are present. Flow rates over the catchment area were reportedly 75-100m/hr giving an approximate travel time of 2-4 days from the input at Ballybreen to Elmvale Springs and around 1-3 days to the private supply wells. As such, there is currently a potentially significant risk to human health receptors from the discharge at Ballybreen in the event that abstracted water from impacted wells is ingested without adequate treatment. This issue and the requirement to prevent or limit direct discharges of potentially hazardous substances to groundwater (under the Groundwater Regulations) has resulted in the conclusion that improvements in the degree of treatment provided by the WWTP is required in order to mitigate this risk.
This risk assessment has included the development of target quality criteria that if met by the improved effluent treatment at Kilfenora should prevent adverse impacts to the identified receptors.
There are currently no requirements to complete groundwater compliance monitoring for the Kilfenora WWTP discharge. However A key aspect of authorisation of discharges to groundwater includes the need for compliance monitoring. The most suitable point for compliance point monitoring is the final effluent discharge point at Ballybreen.
It is understood that Irish Water has engaged engineering consultants to complete a design upgrade for the WWTP at Kilfenora. This is understood to examine the possibility of tertiary treatment with either a percolation area or reed bed system to end the direct discharge to groundwater. An ultra violet treatment system will also need to be considered as part of this design to ensure final discharges do not include microbial pathogens.
Geosyntec recommend water quality data at the discharge point to aid in the assessment of potential impacts from the discharge to the aquifer. Water quality at the spring discharge will be required to meet surface water environmental quality standards. It is recognised that due to the rural location other inputs into the system from diffuse sources such as agriculture and OSWWTs may be impacting groundwater quality. The Tier 3 risk assessment should be revisited upon completion of the engineering upgrades to the WWTP. Monitoring data form the discharge can be completed over this period which will allow for a more complete assessment to be made.

Kilfenora Tier 3 Assessment Final.docx 3 26.06.2014
1. INTRODUCTION
1.1. GENERAL INTRODUCTION
Geosyntec Consultants Ltd (Geosyntec) was commissioned by Irish Water to
complete a Tier 3 risk assessment of a municipal Waste Water Treatment Plant
(WWTP) effluent discharge to groundwater located in Kilfenora, Co. Clare.
In 2009 Clare County Council applied for a certificate of authorisation from the
Environmental Protection Agency (EPA) for the direct discharge of final effluent
from the WWTP to groundwater via a local swallow hole. Since the application was
submitted, Clare County Council has been in dialogue with the EPA in relation to
the application. At the time of writing it is understood a certificate of authorisation
for the discharge had not been issued by the EPA.
In parallel with this dialogue with Clare County Council, the EPA was developing
guidance on the authorisation of discharges to groundwater, which was published
in 20111. More recently (January 2014) the EPA issued further draft guidance
specifically in relation to direct discharges to groundwater2.
As outlined above, it is understood that the Kilfenora WWTP discharges direct to
groundwater via a swallow hole. It is our interpretation that the current discharge
does not in comply with the requirements specified in the above-mentioned EPA
guidance and the groundwater regulations underpinning this guidance for the
authorisation of ‘direct discharges to groundwater’. This is due to potentially
deleterious nature of the discharged water. Specifically we do not believe that the
current discharge falls within any of the permissible or exempted pollutant inputs
defined by Regulations 8 & 14 of the Groundwater Regulations (S. I. No. 9 or 2010).
With this in mind, we understand that Irish Water has commissioned consulting
engineers to provide a scheme to improve the level of treatment at the Kilfenora
WWTP through the inclusion of an appropriately engineered percolation area. An
ultra violet treatment system may also need to be considered as part of this
assessment to avoid microbial pathogen contamination.
The Tier 3 risk assessment presented herein has been completed on the assumption
that the improved treatment measures will be put in place and as such, that the
discharge will at that stage be a deemed an ‘indirect discharge’.
Clare County Council recently transferred ownership of the Kilfenora WWTP to
Irish Water as part of the migration of all local authority water infrastructure assets
to the recently established semi-state body Irish Water. Hence this report has been
prepared for Irish Water rather than for Clare County Council.

1.2. OBJECTIVE AND BACKGROUND INFORMATION
Kilfenora is a small village located close to the southern side of the Burren National
Park, approximately 27 km north-west of Ennis, 8 km north-east of Ennistymon and
9 km south-east of Lisdoonvarna in County Clare. The existing Kilfenora WWTP,
which was constructed in 1974, is located to the west of the village. The WWTP
currently includes an activated sludge unit with final effluent discharging directly
to a swallow hole situated approximately 600m to the west of the village at
Ballybreen. There are proposals to upgrade the WWTP; however up to the date of
asset transfer to Irish Water from Clare County Council, the local authority had not
received the necessary funding to enable this upgrade to proceed. Clare County
Council is understood to have considered other treatment of the effluent including
a percolation area, to end the direct discharge.
The primary aims of the study are to satisfy a request from the Environmental
Protection Agency (EPA) for a Tier 3 risk assessment for the above discharge,
taking into account planned improvements to upgrade the WWTP. This request
from the EPA is linked to correspondence relating to an application lodged with the
EPA by Clare County Council in December 2009 for a Waste Water Discharge
Certificate of Authorisation for Kilfenora WWTP (Application number A0079-01),
as required by the Wastewater Discharge (Authorisation) Regulations, 2007 (S.I.
No. 684 of 2007).
The overarching goal of the Tier 3 risk assessment is to demonstrate the site’s future
compliance with the Groundwater Regulations (S I No. 9 of 2010).
The Groundwater Regulations aim to give effect to the measures needed to achieve
the environmental objectives established for groundwater by the Water Framework
Directive (WFD) and the Groundwater Directive (GWD). Quoting from Regulation
2 of the Groundwater Regulations, the objectives of the WFD include the following:
prevent [in the case of hazardous substances] or limit [in the case of non-
hazardous substances] the input of pollutants into groundwater and to prevent the
deterioration of the status of all bodies of groundwater,
protect, enhance and restore all bodies of groundwater and to ensure a balance
between abstraction and recharge of groundwater, with the aim of achieving good
groundwater status by not later than 22 December 2015,
the reversal of any significant and sustained upward trend in the concentration of
any pollutant resulting from the impact of human activity in order to
progressively reduce pollution of groundwater…

The range of substances deemed ‘hazardous’ and ‘non-hazardous’ from a
groundwater quality perspective are set out in the EPA (2010) guidance
“Classification of Hazardous and Non Hazardous Substances in Groundwater.”
None of the listed hazardous materials are known to be present in the discharge at
Ballybreen swallow hole. However, the non-hazardous materials listed in the EPA
2010 guidance that are likely to be present in the discharge include ammonium,
nitrate and phosphate. Whilst the EPA 2010 guidance does not explicitly reference
microbial pathogens (e.g. coliform bacteria, E. Coli, Enterococci, Cryptosporidium)
These pollutants are covered by other statutory instruments such as the European
Communities (Drinking Water) Regulations 2000 (S.I. No. 439 of 2000).
1.3. RECENT SITE ASSESSMENTS
The most relevant documents that are available for the Tier 3 assessment are two
tracer studies completed by Dr David Drew (Trinity College Dublin) on behalf of
Clare County Council. These tracer studies are the only site specific work
completed to date from which it is possible to gauge the current impact of the
WWTP discharge. The scope and findings of these studies are summarised below.
1.3.1. D. Drew (TCD) Tracer Study 2001
Clare County Council initially commissioned Dr Drew to undertake a tracer test
study at the Ballybreen swallow hole (i.e. the discharge point of the Kilfenora
WWTP) in June and July of 2001. The main aim of the initial tracer study was to
determine the location of the outlets from the swallow hole and comment on how
this interacts with the local hydrology and hydrogeology of the area. A series a
tracer tests were completed using fluorescent dyes during periods of high and low
spring, stream and river flows. Thirteen monitoring points were sampled (8 springs
and 5 surface water locations). These are illustrated by Figure 1. The following
conclusions were drawn in the report produced for this study:
At low flow conditions, water from Ballybreen flows only to springs
feeding the upper part of the River Fergus catchment to the east. Estimated
groundwater velocities are in the order of approximately 60-125 m/hr
At high flow conditions (following a period of prolonged heavy rainfall)
water from Ballybreen flows to all of the springs in the middle River
Fergus valley. Groundwater velocities for this condition were estimated to
be in the order of 150-300 m/hr. In addition, under high flow conditions,
connection was identified from the Ballybreen Swallow Hole to the
Cloongarve stream to the west. Groundwater velocities to that location
were estimated to be in the order of 150 m/hr
The highest tracer concentrations (indicating the strongest connectivity
with Ballybreen swallow hole) were recorded at the Roughan then
Poulnaboe and then Elmvale Springs to the east (See Figure 1)
No direct connection between Ballybreen and Drumcliff or Pouladower

Springs was noted during either tracer test.
1.3.2. D. Drew (TCD) Tracer Study 2012
Clare County Council commissioned an additional tracer study of the swallow hole
at Ballybreen in 2012. The main aim of this study was to better characterise the
underground flow path(s) between the Ballybreen swallow hole and its known
reappearance in springs feeding the River Fergus upstream of Lough Inchiquinn to
the east. A particular emphasis was placed on assessing if water from Ballybreen
may be being intercepted by several private domestic water supply wells located
between the swallow hole and the springs feeding the River Fergus. The main
findings of the report were:
Five domestic wells (see Figure 1) and three springs were sampled during
the tracer study
Tracer was detected in four of the 5 boreholes sampled during the study
demonstrating a connection between the Ballybreen discharge and these
wells. Only the samples collected from the Killinaboy GWS well (the most
easterly well in the study) were found to contain no detectable tracer
Tracer was also detected in two springs feeding the River Fergus, again
demonstrating a connection between Ballybreen and these springs
Groundwater flow rates estimated from this test were in the order of 75-
100 m/hr. These values are understood to be similar rates measured on the
Burren
The main conclusions of the report are that whilst conduit flow
predominates between Ballybreen and the spring outlets to the east there is
also a component of lateral dispersion to the north and south which
accounts for the detection of tracer in the domestic supply wells which are
likely located at offset positions from the main flow conduit system.
A schematic diagram of the groundwater flow described above in conduits and
laterally through dispersion for both high and low water table conditions is
illustrated in Figure 2.
1.3.3. Clare County Council Monitoring Data
Clare County Council has provided the monitoring results for the Kilfenora WWTP
for 2013. The results are included as Appendix B. Influent and effluent water
quality was monitored monthly for Biochemical Oxygen Demand (BOD), Chemical
Oxygen Demand (COD) and Suspended Solids (SS) as per the Urban Waste Water
Directive (UWWD) conditions placed on the WWTP. All effluent samples were
below their respective emission limit values. BOD/COD/SS pollutant loading
reductions were 96%, 88% and 86% respectively through the current treatment
system.
Flow rate data for the WWTP influent for the year 2013 was also provided from

Clare County Council in this spread sheet. The average influent flow rate for the
year 2013 was 146 m3/day with a maximum of 304 m3/day.
The data for the Poplar Bridge monitoring location was also included for the period
2009-2013. Poplar Bridge is a monitoring location used by Clare County Council on
the River Fergus downstream of where the Ballybreen discharge resurfaces in the
head waters of the River Fergus (see Figure 1). The surface water samples collected
on a monthly basis at Poplar Bridge are analysed for pH, BOD, dissolved oxygen,
ammoniacal nitrogen, nitrate, nitrite, total organic nitrogen, orthophosphate and
total phosphorous. It is noted that these results represent surface water quality at a
receptor i.e. the River Fergus. The water quality results are consistent over the
period 2009-2013 with little change in any of the parameters analysed with the
exception of total phosphorous which has decreased from an average of 0.6mg/l in
2009 to 0.08 mg/l in 2013.
The European Communities Environmental Objectives (Surface Waters)
Regulations (S.I. No 272 of 2009) provides surface water Environmental Quality
Standards (EQS) that can be used to provide an indication of the surface water
quality at the discharge point. Applying these standards to the Poplar Bridge
monitoring data shows the levels of BOD, dissolved oxygen saturation and
ammoniacal nitrogen at the monitoring point indicate a ‘High’ status surface water
body. There is no EQS available for orthophosphate or total phosphate (the EQS
being for Molybdate Reactive Phosphorous (MRP)).
2. ENVIRONMENTAL SITE SETTING
Kilfenora village is located close to the southern edge of the Burren National Park,
approximately 27 km north-west of Ennis, 8 km north-east of Ennistymon and 9 km
south-east of Lisdoonvarna. Kilfenora is a small village in a rural location. The
WWTP is immediately surrounded by agricultural land with a school close by to
the south. A private dwelling is constructed to the east of the WWTP in relatively
close proximity to the site boundary.
The existing Kilfenora WWTP was constructed in 1974, and is located to the
western outskirts of the village. The WWTP includes an activated sludge unit with
final effluent discharging directly to a swallow hole situated approximately 600m to
the west of the village at Ballybreen. The locations of the WWTP and the discharge
point at Ballybreen swallow hole are illustrated by Figure 1.
2.1. GEOLOGY
The regional geology of the Kilfenora area is dominated by Dinantian Pure Bedded
Limestone’s to the east (Lissylisheen and Ballyelly members) and Namurian Shales
(Clare shale formation) to the west. The discharge point of the WWTP at Ballybreen
swallow hole lies close to the boundary between the Carboniferous Limestone and
the Namurian Shales. Locally Ballybreen is surrounded on all sides by shale except

to the east. Drew (2012) describes the local geology of the area as having a series of
swallow holes along the eastern boundary between the shales and the limestone
including the Ballybreen swallow hole. Karst features dominate the Burren and
previous tracer studies by Drew (see Section 1.3 above) demonstrate that conduit
flow is significant in the area as illustrated by the very rapid groundwater velocities
measured through tracer testing.
Local to the WWTP the thickness of subsoil is unknown but likely to be thin or
absent based on the GSI designated aquifer vulnerability of ‘extreme with rock at
surface/Karst features’. Further the Teagasc subsoil database describes the subsoil
in the area as Karst, indicating no subsoil in the area with Karst at the surface.
No borehole or trial pit logs are available to confirm the geological sequence at the
WWTP. As such there is likely to be limited potential to develop a percolation
system at the site using the natural soil profile as part of the planned upgrades. It is
understood the treated effluent discharge point at Kilfenora is currently directed to
a stream that bypasses any subsoil and directly enters the Karst limestone bedrock
via the Ballybreen swallow hole.
2.2. REGIONAL HYDROGEOLOGY
As stated above in Section 1.3, tracer studies have shown that the water sinking at
Ballybreen swallow hole is hydraulically connected to springs to the east which
feed the head waters of the River Fergus. There is also a component of flow that
feeds a spring or springs to the west during high water levels. The Geological
Society of Ireland (GSI) classifies the aquifer in the study area as a regionally
important aquifer – Karstified (conduit). The Namurian Shale to the west is
classified as a poor aquifer – bedrock which is generally unproductive.
The 2012 tracer study identified 5 wells in the catchment area between Ballybreen
and the spring system to the east. All of these wells were shown to be in hydraulic
connection with Ballybreen, albeit through a weaker connection than the main
conduit connections with the spring system.
The Groundwater Body (GWB) underlying the majority of the study area is
identified by the EPA as Craggaunboy GWB. The approximate GWB boundaries in
the study area are shown in Figure 3. Craggaunboy GWB is classified by the EPA as
a poorly productive aquifer. However, the previous tracer studies have
demonstrated that the limestone bedrock in the study catchment area exhibits
karstic features which would suggest that a Karst Aquifer classification may be
more accurate for this GWB. The classification for both the neighbouring Burren
and Ennis GWBs is Karst with the latter containing the spring system to the east
which has been demonstrated to be connected to the Ballybreen swallow hole and
which in turn provide the head waters of the River Fergus.
The Water Framework Directive (WFD) risk score for Craggaunboy GWB is
‘possibly at risk of not achieving good status’. The WFD risk score for Ennis GWB is
‘at risk of not achieving good status’. The WFD risk score for the Burren GWB is

‘strongly expected to achieve good status’. There is no groundwater quality data
available from the EPA monitoring programme for the study catchment area. The
current EPA groundwater quality status (2007-2009 data) for Burren and
Craggaunboy GWBs is ‘good’, with the Ennis GWB status given as ‘poor’.
There are no known source protection zones (either EPA or GSI) in the study area.
2.3. LOCAL HYDROGEOLOGY
Little additional information beyond the results of the tracer studies is currently
available to characterise the local hydrogeological conditions. Specifically, it has
not been possible to obtain records for any boreholes drilled in the area, there is
limited groundwater elevation data contained within the tracer study and no pump
test results have been obtained.
No other information in relation to the Ballybreen Swallow Hole characteristics
locally is understood to be available. The tracer tests have demonstrated that the
main flow zone under dry weather is to the east towards the River Fergus Spring
system with a component of flow locally from Ballybreen to the west under high
flow conditions. Currently available information on water quality in the catchment
area is summarised below.
2.4. GROUNDWATER QUALITY
Groundwater monitoring was completed in May 2012 by Clare County Council as a
follow up to the April 2012 tracer study. Monitoring wells identified as having a
connection with Ballybreen during the tracer study were sampled for pathogens. A
summary of the results for these analyses is presented in the table below. The
results below are all samples collected prior to any treatment. The results for the
Roche well (not thought to have been included in the 2012 tracer study) are
included as provided by Clare County Council. The Roche well is understood to be
located in the townland of Lisket, Kilfenora.

prGWS (Private Group Water Scheme)
Upon completion of the May 2012 monitoring programme Clare County Council
put in place a programme of upgrades to the water distribution network.
Leamaneh prGWS was decommissioned and all other households in the monitoring
programme were offered connection to a mains supply.
A comparison has been undertaken of the bacteriological monitoring results with
the tracer test data obtained in April 2012. The tracer test identified the Keane well
as having the strongest connection to Ballybreen swallow hole. However the Keane
pathogen monitoring was ‘non-detect’ for the specific microbial species tested for in
the May 2012 samples. This result is anomalous as the Roche well also thought to
be located in the townland of Lisket was heavily impacted by microbial pathogens.
Overall three of the five wells tested positive for microbial pathogens. However, the
results must be treated with caution as it is not possible to rule out other sources of
microbial contamination detected in these wells such as OSWWTS.
Clare County Council has also completed routine monitoring of the Kilnaboy
prGWS and Leamaneh /Roughan prGWS over the period 2009-2013. The results
are attached as Appendix C. The Leamaneh well is located approximately half way
from Ballybreen to Elmvale Springs and the Kilnaboy well is located to the
southeast of Roughan Springs close to the River Fergus. Both wells are
downgradient of the Ballybreen discharge (see Figure 1). Positive detections have
been recorded for Coliform bacteria including E. Coli over the monitoring period at
both wells.
2.5. SURFACE WATER FEATURES
The nature of the Karst geology in the study area means that surface water and
groundwater are closely connected. As stated above a series of swallow holes in the
west close to the limestone-shale boundary are connected via Karst conduits to
springs feeding the headwaters of the River Fergus located from approximately 5-6
km to the southeast of Ballybreen. The tracer studies summarised above also
demonstrate that a component of groundwater flow (especially under high flow
conditions) travels to the west to feed the local surface water system at Cloongarve
stream which is part of the River Dealagh catchment which ultimately discharges to
Liscannor Bay.
Clare County Council provided Geosyntec with surface water quality monitoring at
Poplar Bridge on the River Fergus over the period 2009-2013 (Appendix B). The
Poplar Bridge monitoring location is down stream of the main spring discharges
forming the River Fergus and up stream of Lough Inchiquin (Figure 1). The results

are summarised in Section 1.3.2. Overall the surface water quality of the River
Fergus in this location is classified by the EPA as ‘good’. Considering that the water
quality measured at the Poplar bridge location represents inputs not only from the
current discharges to the Ballybreen swallow hole but also OSWWTS and other
diffuse sources such as agriculture the inputs at Ballybreen swallow hole do not
appear to be materially impacting surface water quality in the River Fergus.
3. CONCEPTUAL SITE MODEL (CSM)
Outlined below is a summary of the conceptual Site Model (CSM) which describes
the potential source term, contaminant migration pathways and potentially
exposed receptors associated with the proposed discharge to the Ballybreen
swallow hole. A schematic cross section illustrating the CSM is presented as Figure
2.
3.1. POTENTIAL SOURCE TERM
As outlined previously, the Kilfenora WWTP discharge point is the Ballybreen
swallow hole.
Clare County Council undertakes routine monitoring of the final effluent from
Kilfenora WWTP prior to discharge (as discussed in Section 1.3 above).
The results of the Kilfenora WWTP monitoring programme for 2013 are included as
Appendix B. Presently the discharge is monitored for BOD, COD and suspended
solids as per the UWWT directive.
Microbial pathogens are not analysed as part of the Kilfenora WWTP monitoring
programme. The table below gives a summary of the final effluent quality at
Ballybreen and the efficiencies achieved as part of the treatment process for 2013.

The final effluent discharge point is to a stream immediately before this enters the
Ballybreen swallow hole. The flow rates and water quality parameters of this
stream (and therefore any potential dilution of the effluent) before it enters
groundwater are unknown.
At the time of preparing this draft report, Clare County Council has commenced in
an intensive period of monitoring the final effluent discharge for Pathogens, as well
as N and P species to better characterise the current final effluent discharge.
As outlined previously, the main contaminants of potential concern (COPC) from
the discharge at Ballybreen are considered to be microbial pathogens, nitrogen and
phosphorous compounds. The EPA 2011 Guidance on the authorisation of
discharges to groundwater states the following in relation to microbial pathogens:
“Although the Groundwater Regulations focus on chemical substances, and do not
explicitly reference microbial pathogens (e.g. coliform bacteria, E. Coli, enterococci,
Cryptosporidium), these pollutants are nonetheless covered by other statutory
instruments such as the European Communities (Drinking Water) Regulations,
2000 (S.I. 439 of 2000)”.
The drinking water regulations state that drinking water should be free from
microbial pathogens, therefore any detection of same in drinking water supply is a
fail.
Nitrogen and phosphorous species are the key compounds in eutrophication of
surface waters (especially phosphates) and therefore are included as COPCs.
As outlined previously, it is anticipated that an upgraded WWTP at Kilfenora
would need to achieve relatively stringent discharge criteria. We have based the
remainder of this risk assessment on the basis that the current ‘direct’ discharge
will need to achieve substantially more stringent quality than those that are likely
to be being achieved at present. A set of criteria based on protecting receiving
waters are set out in the following table. It is noted that an ultra violet treatment
system will also need to be considered as part of this design to ensure final
discharges do not include microbial pathogens.

3.2. PATHWAYS
The key contaminant migration pathways for effluent discharged to the Ballybreen
Swallow hole have been established in the tracer studies completed by D. Drew
(TCD) in 2001 and 2012. The tracer tests established that groundwater flow in the
area is dominated by Karst conduit flow predominantly in a northeast to southwest
direction along a network of solution enhanced bedrock fractures. The tracer test
estimated that groundwater flow in the region of 75-100 m/hr over the study area
from Ballybreen to Elmvale Springs some 6.5km to the south east (similar to
groundwater velocity estimates over much of the Burren).
Other features of the tracer test data was a component of flow from the Ballybreen
swallow hole migrating west towards the Cloongarve stream to the west under
high flow conditions (potentially resulting in the connection of a separate higher
elevation and westerly orientated conduit system (see Figure 2).
The detection of tracer in 5 abstraction wells, in the 2012 Tracer Study, located at
varying distances to the north of a line between the swallow hole in the west and
the main springs receiving water from Ballybreen to the east implies a component

of lateral flow in a more northerly (and potentially southerly) direction away from
the swallow hole. This is a relatively unusual feature in Karst groundwater flow
and may potentially result in relatively widespread impacts to groundwater quality
in the aquifer when compared to impacts that are more focused along isolated
conduits. Figure 2 gives a schematic representation of the flow components
described above.
3.3. RECEPTORS
The following receptors for discharges made to the Ballybreen Swallow Hole were
positively identified in the 2001 and 2012 tracer studies (refer to Figure 1 for
locations):
Lisket (Keane) well approximately 2.12km from Ballybreen
Ballybane (Mellet) well approximately 3.25 km form Ballybreen
Ballygannor (O’Dea) well approximately 3km from Ballybreen
Leamaneh well approximately 3.25 km from Ballybreen
Elmvale Springs approximately 5.4km from Ballybreen
Kilnaboy Springs approximately 5.9km from Ballybreen
Springs feeding the Cloongarve stream 0.65Km to the west form
Ballybreen under high flow conditions (See Figure 2).
It is noted that all users of wells identified as being potentially impacted in the 2012
tracer study were offered connection to mains supply and the Leamaneh GWS was
decommissioned. It is recognised that there may be other unregistered wells in the
area that use the Karst aquifer for drinking supply.
The River Fergus which receives water from Elmvale Springs is also considered to
be a receptor. An Appropriate Assessment (as per the EPA guidelines on
Appropriate Assessment for WWTP) was completed for the River Fergus as part of
the discharge certificate application made by Clare County Council for Kilfenora
WWTP. The River Fergus is a designated surface water under the European
Communities (Quality of Salmonid Waters) Regulations (S.I. 293 of 1988). The
assessment concluded that no impact linked to the discharge from the treatment
plant is observed or considered likely on Salmonid species, taking account of the
effluent quality and the high status of the receiving waters downstream of the
discharge.
3.4. SPR LINKAGES – RISK SCREENING
The following Source-Pathway-Receptor linkages are noted for the effluent
discharge at Ballybreen swallow hole:

system via the Ballybreen swallow hole. There are wells in the study area that are
using groundwater for drinking water supply. There is a potential for drinking
water to be impacted by pathogenic bacteria from the currently discharged effluent.
The 2012 tracer study identified private wells in hydraulic continuity with the
Ballybreen discharge. Subsequent sampling of these wells for microbial pathogens
was positive in three of these wells (Section 2.4). Whilst the pathogenic bacteria
may be sourced from other inputs such as private OSWWTs the positive detections
of tracer suggest the potential for a contribution from Ballybreen. It is noted that all
wells positively identified in the 2012 tracer study have been offered a mains water
supply but not all may have accepted. As such preliminary risk screening for this S-
P-R linkage categorises the potential risk as to human health receptors as high
where treatment of the abstracted water is ineffective. However upon completion of
the upgrade works to the WWTP the pollutant linkage will be addressed at the
source, reducing the potential risk significantly.
Ecological – Water Quality in the River Fergus
The 2012 tracer study identified a direct link between Ballybreen and the upper
reaches of the River Fergus. Surface water quality data from Poplar Bridge (on the
River Fergus indicates that discharges from the final effluent are not having an
adverse impact on the water quality of the River Fergus (Section 1.3.2). Considering
the fact that the discharges from other sources such as agricultural inputs and
OSWWTS could be contributing to the detections at Poplar Bridge and that the
results indicate a good water quality status the potential risk associated with this S-
P-R linkage is low. It is understood that no monitoring of water quality is
undertaken for the Cloongarve stream which periodically may receive water from
the Ballybreen swallow hole under high flow conditions, as such it is not possible to
evaluate the degree of impact, if any, resulting from this connection.
4. GROUNDWATER COMPLIANCE MONITORING
There are currently no requirements to complete groundwater compliance
monitoring for the Kilfenora WWTP discharge. It is noted that guidance for the
authorisation of discharges to groundwater includes for setting compliance points
for monitoring potential impacts to receptors. At the time of writing Clare County
Council were engaged in an intensive monitoring programme for microbial
pathogens, N& P species at the Kilfenora WWTP discharge point. As other inputs
to the aquifer (such as diffuse agricultural inputs or OSWWTS) may result in false
positive detections in the GWB the most sensible location for compliance
monitoring is at the discharge point of the final effluent at Ballybreen.
Routine monitoring of the surface water receptor is on-going by Clare County
Council at Poplar Bridge. Water quality results at this receptor should comply with
surface water Environmental Quality Standards (EQS).

5. CONCLUSIONS & RECOMMENDATIONS
The final effluent from the Kilfenora WWTP is currently discharging to a swallow
hole in the townland of Ballybreen to the west of the village. Clare County Council
applied to the EPA for a discharge certificate for this practice in 2009. As part of the
application process the EPA requested a risk assessment to consider the likely
impacts that this discharge was having on receiving groundwater and surface
waters.
The discharge criteria of the final effluent for BOD/COD and suspended solids are
routinely passed. There is no requirement to complete any other water quality
monitoring at present at the plant. However, we consider that the current discharge
is non compliant with the requirements specified in the EPA guidance and the
groundwater regulations underpinning this guidance. Specifically with regards to
authorising a direct discharge to groundwater with regards to specific constituents
of the discharge. As a result, we understand that Irish Water has engaged
consulting engineers to design upgrades to the Kilfenora WWTP to include a
percolation system. This means that the final effluent water quality will improve
and the discharge itself will no longer be classified as a direct discharge to
groundwater. An ultra violet treatment system will also need to be considered as
part of this design to ensure final discharges do not include microbial pathogens.
Tracer tests completed in 2001 and 2012 have identified a direct linkage between
the swallow hole and springs to the southeast which feed the headwaters of the
River Fergus. Further private wells in the catchment area were also shown to be
hydraulically connected. These wells were subsequently sampled for microbial
pathogens in 2012 and found to be impacted. A mains water supply was offered to
all affected wells by Clare County Council. The main flow zone was direct along
conduits as is typical for Karst limestone systems, albeit with a component of
dispersion to the north and south to potentially impact water quality in private
wells.
There is little groundwater quality data available for the study area. Surface water
quality at the River Fergus has shown to have a good status.
A conceptual site model was developed presenting all known source pathway
receptor linkages. The CSM relies heavily on the pollutant linkages suggested by
the tracer studies completed for the area.
The main substances of potential concern in the current discharge are microbial
pathogens and N and P species. Direct linkages between the swallow hole at
Ballybreen and private wells in the study area represent the main risk driver for the
study area. A pollutant linkage with the River Fergus is confirmed however surface
water monitoring of the River Fergus shows that it is currently not impacted form
the discharge at Ballybreen. It is recognised that upgrades to the WWTP at
Kilfenora will significantly reduce the potential human health risks by breaking the
pollutant linkage at the source.

Geosyntec recommend water quality data at the discharge point is collected to aid
in the assessment of potential impacts from the discharge to the aquifer. The most
appropriate location for monitoring microbial pathogen compliance is at the
discharge point at Ballybreen. Water quality at the spring discharge will be
required to meet surface water environmental quality standards. It is recognised
that due to the rural location other inputs into the system from disuse sources such
as agriculture and OSWWTs may be impacting groundwater quality.
