1. INTRODUCTION

JRE Environment (JRE) was retained by Limerick City and County Council to complete Quarter 4, 2018

odour monitoring and sampling at the Gortadroma Landfill site in Ballyhahill, Co. Limerick. The site is a

closed landfill site with an operational bring centre. Monitoring and sampling was completed at on-

site and background sample locations external to the site to assess quarterly odour and

concentrations of contaminants of concern associated with odour compounds. The four (4) pre-

determined monitoring locations (i.e., M1, M2, M7 and M10) are outlined on Drawing Fig.2, attached.

All sampling was completed on October 9th, 2018 under the appropriate Health and Safety

Regulations, including; Safety, Health and Welfare at Work Act, 2005 and the Safety, Health and

Welfare at Work (General Application) Regulations, 2007 and associated Regulations. All odour

monitoring and sampling was completed with reference to Schedule C.3 of Environmental Protection

Agency (EPA) Waste Licence Ref. W0017-04 (Waste Licence).

2. ODOUR MONITORING

The purpose of the odour monitoring and sampling programme was to assess quarterly air quality at

four (4) monitoring locations to assess the potential for odour impacts at those locations. The odour

assessment locations are outlined in Table A and are shown on Drawing Fig.2 attached.

2.1. Scope of Work

The following tasks were completed as part of the scope of work for the odour monitoring and sampling

assessment:

Collect air samples at the 4 pre-determined monitoring locations for assessment of contaminants

of concern outlined in Schedule C.3 of Waste Licence;

Collect samples using Gastec colourmetric detector tubes and/or adsorption tubes for hydrogen

sulphide (H2S), mercaptans (propyl mercaptans), organic acids (acetic acid, isobutyric acid, valeric acid

and propionic acid) and total organic carbon (TOC).

Prepare a quarterly report of results for Limerick City and County Council.

2.2. Odour Chemical Sampling

Concentrations of contaminants of concern were measured at each monitoring location using the

appropriate parameter detector tube and a Gastec Pump (GasGV-100S). The details of the sampling

procedure are outlined in Table B.

Table B: Chemical Sampling Details

Parameter Cat Ref. No. No. of Gastec Gas-GV-100S Pump Strokes for Sample

Limit of Detection (ppm)

hydrogen sulphide GAS4LT 1 0.1 ppm – 4 ppm

mercaptans GAS70L 1 0.1ppm – 8 ppm

acetic acid GAS81L 2 0.125 ppm – 25 ppm

isobutyric acid GAS81L 1 0.325 ppm – 13 ppm

valeric acid GAS81L 1 0.38ppm – 15 ppm

propionic acid GAS81L 1 0.25 ppm – 10 ppm

Concentrations of each parameter were determined colourmetrically using a specific reagent for each

chemical parameter. Each sample was collected by placing the specific detector tube into the sample

pump and pulling a known volume through the tube. The appearance of a discoloration indicated the

presence of the compound of interest.

To correct for barometric pressure the sample results were adjusted using the following formula:

Tube Reading x 1013 (hPa)

Barometric Pressure (hPa)

2.3. Odour Sniff Test

In addition to the chemical sampling completed at each sample location JRE personnel also completed a

sniff test at each location with reference to the EPA Air Guidance Document AG5. The field sheets are

included in Appendix I.

3. ODOUR RESULTS

The results of the Quarter 4, 2018 odour sampling completed at Gortadroma landfill on October 9th

2018, are presented in Table C and D. The odour sniff test results sheets for each sampling location are

provided in Attachment 1.

4. CONCLUSIONS

The results of the chemical sampling at the four odour assessment locations (i.e., M1, M2, M7 and M10)

at the Gortadroma landfill site indicated no detectable compounds of concern outlined in Schedule C.3

of the site Waste Licence. The subjective odour assessment completed with reference to AG5 at the

same monitoring locations during chemical sampling found no odour related to landfill activities at any

of the odour assessment locations.
