INTRODUCTION
RPS was commissioned by Jamestown Metal Resources Ltd (JMR) to carry out groundwater and
surface water quality monitoring at their facility on the Jamestown Road, Inchicore, Dublin 8. The
scope of work was to collect groundwater samples from three groundwater-monitoring wells
(MW01, MW02 and MW04) and one surface water location (MH01) within the site boundary.
In December 2013, the facilities licence (Register Number: P0392-01) was amended by the EPA to
conform to the provisions and requirements of Council Directive 2010/75/EU and as such is deemed
an Industrial Emissions Licence. No schedule of monitoring or emission limit values are specified in
the JMR Industrial Emissions licence (Register No. P0392-01).
RPS has used available previous monitoring reports from White Young Green as the basis for the
parameters monitored and groundwater results are discussed with reference to European
Communities Environmental Objectives (Groundwater) Regulations 2010 (S.I. No. 9 of 2010) where
applicable or against the EPA Interim Guideline Values.

METHODOLOGY
3.1
GROUNDWATER
Groundwater samples were collected from 3 no. on-site groundwater monitoring wells (MW01,
MW02 and MW04) using dedicated Waterra tubing, in accordance with RPS’s standard sampling
protocol. A non-return foot valve was fixed to the bottom of the tubing and inserted into the well,
close to the base of the borehole. Separate tubing and foot valves were used at each monitoring
well to eliminate the possibility of cross contamination.
ru
se
.
Groundwater in the well casing is not considered representative of the groundwater quality at a
given location. For this reason, three well volumes were purged from each well prior to collection of
the groundwater sample. By the time purging was complete all field test water parameters (namely
pH, Temperature, Electrical Conductivity and Dissolved Oxygen) should be within 10% variance in
three consecutive measurements. This ensures that the groundwater sample extracted from the
monitoring borehole was representative of the water held in the subsurface strata and not water
held stagnant in the borehole casing. The purged volumes were calculated on-site from the
measured static water levels and total well depths using an electronic dip meter.

In order to ensure optimal evaluation, the pH, conductivity and temperature of the extracted water
should be continually monitored using a field meter, which is calibrated on the day of use.
Groundwater samples were collected in laboratory supplied containers and stored in chilled cool
boxes following sampling and during transit to the laboratory. A rigorous chain of custody procedure
was used during the sample round.
Co

en
All groundwater samples were analysed at a UKAS accredited laboratory, ALS Environmental Limited
UK for the suite of analyses listed in Table 3.1. Table 3.1 also indicates the analytical techniques used
by the laboratory.

3.2
SURFACE WATER
In accordance with Industrial Emissions licence P0392-01, a surface water sample is required to be
collected from MH01. A surface water sample was taken from by a sampling container connected to
an extendable pole. Care was taken not to disturb the final sampling location in order to ensure that
no suspended sediment, macro detritus or algae were entrained in the bottle.
The sampling container was removed from the water and the contents inspected for anomalous
materials, such as sediment of flocculent materials. On occasion, when the sample became
contaminated with sediment the sample bottle was re-rinsed and the sampling round repeated. The
pH, conductivity and temperature of the extracted water were monitored using a field meter, which
was calibrated on the day of use.
Laboratory analysis was conducted for the list of parameters detailed in Table 3.2. Field observations
were also made of weather conditions and any unusual or special conditions at the time of sampling.
All laboratory analysis was carried out in accordance with UKAS accredited techniques as mentioned
previously.

DISCUSSION OF RESULTS
5.1
GROUNDWATER MONITORING
The results of the second bi-annual monitoring round for 2015 are included in Table 4.1 and 4.2.
Groundwater results are compared to the European Communities Environmental Objectives
(Groundwater) Regulations 2010 (S.I. No. 9 of 2010) where applicable or against the EPA Interim
Guideline Values (IGV) as set out in the Interim Report “Towards Setting Guideline Values for the
Protection of Groundwater in Ireland” 2004. Exceedances of the guideline values are highlighted
within the tables.
5.1.1 Field Measurements
Field measurements recorded on the day of sampling are presented in Table 4.1. Field
measurements of pH levels were recorded in the range of 6.33 and 7.07 which is within the EPA
Interim guideline range of >6.5 & <9.5 with the exception of the reading of 6.33 at MW04.

Electrical conductivity levels were compared against the Groundwater Threshold Value range of 800
– 1875 μS/cm and were within the threshold value range at MW04. Electrical conductivity
measurements of 772 μS/cm and 481 μS/cm were recorded at MW01 and MW02 respectively during
this monitoring round.
Temperature levels ranged from between 12.9 and 14.1 °C which is below the IGV of 25°C and
dissolved oxygen measurements were recorded between 3.16 ppm and 4.18 ppm.
Co

en
Observations relating to colour varied from well to well as detailed in Table 4.1 although all wells
had a degree of fine sediment in the water. H2S odours were detected at MW02 and MW04 but no
odour was detected at MW01.
5.1.2
Results of Metal Analysis
The results of the metal analysis indicate that Potassium has exceeded its Interim Guideline Value at
two locations. The results are consistent with the previous monitoring event.
There is no Groundwater Threshold Value for Potassium therefore the results are compared against
the EPA IGV of 5 mg/l. Potassium concentrations were recorded above the IGV at MW01 and MW04
during the current monitoring event. Potassium concentrations above the IGV were also detected at
these locations during the first bi-annual event of 2015 in May. Between December 2010 and June
2014 concentrations above the IGV were detected at MW04 only. The Potassium concentration
recorded at MW04 during this current bi-annual round was 15.8 mg/l, which is slightly decreased
from the May 2015 concentration of 16.4 mg/l. A level of 6.82 mg/l was detected at MW01 during
this current bi-annual event, which has noted a decrease from 7.37 mg/l during the previous biannual event in May 2015.
Potassium is an indicator of potential nutrient pollution from farmyard runoff or sewage rather than
a contaminant. The EPA Parameters of Water Quality report (2001) states there is no implications of
toxicity in relation to Potassium. Jamestown Metal Resources is located in an urban environment
MDE0868Rp0029
10
EPA Export 14-04-2016:01:45:28
Jamestown Metal Resources, Groundwater Monitoring 2015
where several municipal and private sewage systems are likely to be present. It is possible that
leakage from some of these systems is the source of elevated Potassium.
Levels of Zinc and Nickel had been detected in previous monitoring events; however both
parameters were below their respective GTV during this monitoring event at all locations.
All other parameters were below their respective GTVs or IGVs.
5.2
SURFACE WATER MONITORING
The results of the surface water monitoring are included in Table 4.3. The results of the analysis have
been compared to the Environmental Quality Standard (EQS) as referenced in the European

CONCLUSIONS
In accordance with the criteria set out in Industrial Emissions licence P0392-01, groundwater
monitoring was carried out at the JMR site on the 14th of October 2015 corresponding to the second
biannual monitoring event. A suitably qualified consultant from RPS collected groundwater samples
from 3 on-site monitoring wells and submitted these samples to an accredited laboratory for
analysis.
The results presented have been referenced against the European Communities Environmental
Objectives (Groundwater) Regulations 2010 (S.I. No. 9 of 2010) where applicable or against the EPA
Interim Guideline Values as set out in the Interim Report “Towards Setting Guideline Values for the
Protection of Groundwater in Ireland”, 2004.
The results of the metal analysis indicate that Potassium has exceeded its EPA Interim Guideline
Value at monitoring wells MW01 (6.82 mg/l) and MW04 (15.8 mg/l). All other parameters of the
metal analysis were below their respective GTVs or IGVs.
