1.0 INTRODUCTION

1.1 BACKGROUND

The Ophir Road Resource Recovery Centre is located approximately 3km north-east of the Orange central business district. The area surrounding the property to the north, east and south is predominantly rural or rural residential development. Orange City Council’s sewage treatment works is located immediately west of the facility on the opposite side of Blackmans Swamp Creek.

Ophir Road Resource Recovery Centre is owned by Orange City Council and has been in operation since the mid 1960’s. The site is zoned 5(a) Public Purposes under Orange Local Environmental Plan 2000.

1.2 LICENCE REQUIREMENTS

The Ophir Road Resource Recovery Centre currently operates under Environment Protection Licence 5956 (EPL 5956), issued under Section 55 of the Protection of the Environment Operations Act 1997 (The Act). This licence governs the design, construction, operation, monitoring and rehabilitation of the facility in accordance with The Act.

Management and operation of the centre is also undertaken in accordance with the Landfill Environmental Management Plan (LEMP, Geolyse, 2013).

Section 5 of EPL 5956 provides instructions on environmental monitoring requirements. Specifically, Condition M2.1 describes the requirements to monitor the concentration of pollutants discharged to groundwater, surface water, leachate, surface gas and sub-surface gas.

Annual reporting requirements that are outlined in Condition R1.1 state:

“R1.1 The licensee must complete and supply to the EPA an Annual Return in the approved form comprising:

a) a Statement of Compliance; and

b) a Monitoring and Complaints Summary.

At the end of each reporting period, the EPA will provide to the licensee a copy of the form that must be completed and returned to the EPA.”

The deadline for the Annual Return that is outlined in Condition R1.5 states:

“The Annual Return for the reporting period must be supplied to the EPA by registered post not later than 60 days after the end of each reporting period or in the case of a transferring licence not later than 60 days after the date the transfer was granted (the 'due date')”

The reporting period for this AEMR is from 1 July 2014 to 30 June 2015. All monitoring data collected prior to this reporting period has also been included in the presentation and analysis of data. Collection of environmental data began at the Ophir Road Resource Recovery Centre in December 1997.

EPL 5956 was varied on 25 June 2014, and applicable to the current next reporting period. The primary implications of the variation included:

Changing the activity "contaminated soil treatment" from a primary activity to an ancillary activity;

Removal of surface and sub-surface gas monitoring requirements;

Provision of and reference to a new location description drawing;

Weekly cover requirement introduced with the option of using alternate covering materials; and

A Pollution Studies and Reduction Program required to be undertaken.

3.0 ENVIRONMENTAL MONITORING RESULTS

3.1 INTRODUCTION

Monitoring results are presented in this section for all environmental monitoring undertaken during the reporting period. The laboratory data are presented, along with an interpretation of trends, variability and anomalies for groundwater, surface water, leachate and accumulated gas. Levels greater than the LEMP provisional limits, any deficiencies in monitoring, environmental incidents and remedial actions undertaken to correct any problems or deficiencies are also discussed.

Monitoring data is summarised in the following figures and in the tables of Appendix A. All laboratory reports and chain-of-custody documentation are included in Appendix B.

3.2 GROUNDWATER

Groundwater monitoring consisted of biannual water level measurements at the six piezometer monitoring stations (ten in the most recent monitoring event) and biannual collection of groundwater samples from these piezometers.

3.2.1 GROUNDWATER LEVELS

Groundwater level measurements are presented for all monitoring stations in Appendix A, Table A1 and are illustrated below in Figure 3.1 for the previous 3 years.

Figure 3.1 Groundwater Levels – Ophir Road Resource Recovery Centre, 2012 to 2015

Groundwater levels remained relatively consistent throughout the reporting period, with BH3 remaining the up-gradient monitoring point. Groundwater elevations of recently installed monitoring locations BH5 and BH6 correspond to down-gradient locations.


ORANGE CITY COUNCIL


3.2.2 GROUNDWATER QUALITY

Complete historical results for each groundwater monitoring event in the reporting period are presented in Appendix A, Tables A2-A3. Monitoring locations BH2A and BH7A were unable to be sampled in the reporting period due to insufficient water volume.

Laboratory measured pH was slightly alkaline and relatively consistent across the site in the reporting period, with values ranging from 7.11 at BH2 (March 2015) to 7.98 at BH3 (September 2014). pH values are indicative of suitable for livestock drinking water, with all values falling within the guideline range of 6.5 to 8.5 (Markwick, 2007). pH of groundwater at all piezometers (with historic data available) decreased during the reporting period.

Electrical conductivity (EC) ranged from 224 µS/cm at BH1A (September 2014) to 3200 µS/cm at BH4 (September 2014). Corresponding total dissolved solids (TDS) concentrations ranged from 150 mg/L to 2,144 mg/L, and are considered suitable for consumption by the most susceptible livestock category, poultry (<3,000 mg/L, ANZECC & ARMCANZ, 2000).

Total alkalinity concentrations ranged from 73 mgCaCO3/L at BH7 (March 2015) to 854 mgCaCO3/L at BH4 (March 2015). Concentrations were generally observed to increase in the reporting period (where historic data was available). The guideline hardness value for potential fouling of waters (350 mgCaCO3/L, ANZECC & ARMCANZ, 2000) was exceeded at monitoring locations BH2, BH3, BH4 and BH5 at the September 2014 and/or the March 2015 monitoring events.

Sulfate ranged from a low of 1 mg/L at BH1 (March 2015) to 297 mg/L at BH7 (March 2015). These concentrations are lower than the 1000 mg/L guideline value for livestock drinking water (ANZECC & ARMCANZ, 2000).

Chloride concentrations in groundwater ranged from 3 mg/L at BH1 (September 2014) to 640 mg/L at BH4 (March 2015). No concentrations of chloride in groundwater exceeded the upper guideline value for irrigation to moderately tolerant crops (700 mg/L, ANZECC & ARMCANZ, 2000) in the reporting period.

Calcium concentrations were all lower than the livestock drinking water guideline value of 1,000 mg/L (ANZECC & ARMCANZ, 2000). Monitoring station BH4 recorded the highest concentration at 281 mg/L (March 2015), and BH1A recorded the lowest at 11 mg/L (September 2014). Concentrations were consistent with historical data.

Magnesium concentrations ranged from 12 mg/L at BH1A (September 2014) to 261 mg/L at BH4 (March 2015) and were consistent with historical data.

Chloride, calcium and magnesium concentrations were all observed to be elevated at monitoring points BH2, BH4, BH5, with average concentrations in groundwater over five times greater than concentrations recorded at monitoring points BH1, BH1A, BH3 and BH7.

Potassium concentrations in groundwater ranged from below the laboratory limit of reporting (LOR) of 1 mg/L to 11 mg/L, and were consistent with historical data.

Sodium in groundwater was recorded to be lowest at BH1 at 11 mg/L (September 2014) and highest at BH7 at 98 mg/L (March 2015). These values are below the irrigation guideline for moderately tolerant crops (460 mg/L, ANZECC & ARMCANZ 2000) and the conservative aesthetic guideline for human drinking water (180 mg/L, NHMRC & NRMMC 2011).

Manganese ranged from below the laboratory LOR of 0.001 mg/L at BH6 (March 2015) to 0.768 mg/L at BH2 (March 2015). Groundwater in BH3 and BH4 were consistently below the long-term (<100 years) crop irrigation guideline value of 0.2 mg/L, while all monitoring locations recorded manganese concentrations below the short-term (<20 years) guideline value of 10 mg/L (ANZECC & ARMCANZ, 2000). Concentrations were consistent with historical data.

Iron was below the laboratory LOR of 0.05 mg/L at BH3 and BH4 (September 2014) and BH3, BH4, BH5, BH6 and BH7 (March 2015). Iron in groundwater was most elevated at BH2, ranging from


ORANGE CITY COUNCIL


0.56 mg/L (September 2014) to 4.93 mg/L (March 2015). For irrigation purposes, iron concentrations in groundwater from BH1, BH1A and BH2 are considered suitable for short-term (<20 years) use and the remainder of points are considered suitable for long-term (<100 years) use (ANZECC & ARMCANZ, 2000).

Fluoride concentrations ranged from below the laboratory LOR of 0.1 mg/L at BH4 (September 2014) to 0.3 mg/L at BH7 (March 2015). All values were lower than the livestock drinking water guideline value of 2 mg/L (ANZECC & ARMCANZ, 2000) and are consistent historical data.

Ammonia concentrations were most elevated at BH2 (3.25 mgN/L in March 2015) which exceeded the LEMP provisional limit, however BH2 has consistently displayed the highest ammonia concentrations. The ammonia concentration recorded in BH2 increased by 2.01 mgN/L during the reporting period. Ammonia concentrations in groundwater from all other monitoring points were below the aesthetic guideline for ammonia in human drinking water (0.41 mgN/L, NHMRC & NRMMC, 2011).

Nitrate concentrations in groundwater ranged from 0.02 mgN/L at BH4 (September 2014) and BH1 (March 2015) to 6.50 mgN/L at BH6 (March 2015). Nitrate concentrations in groundwater from all monitoring points were below the LEMP provisional limit of 10 mgN/L and below the livestock drinking water guideline value of 90.29 mgN/L (ANZECC & ARMCANZ, 2000) at all monitoring locations, however the elevated groundwater nitrate concentration at BH6 will continue to be monitored.

Total organic carbon concentrations in groundwater ranged from below the LOR (<1 mg/L) at BH3 (September 2014) to 16 mg/L at BH4 (September 2014 and March 2015) and BH5 (March 2015).

Total phenolics were below the LOR (<0.05 mg/L) at all groundwater monitoring points. Subsequently all samples were below the LEMP provisional limit of 0.1 mg/L and were within the historical ranges at each site.

No total petroleum hydrocarbon (TPH) fractions were detected at BH1, BH1A, BH3, BH5, BH6 or BH7 during the reporting period. Only the C6-C9 fraction was recorded at BH2, at concentrations of 1.50 mg/L and 2.07 mg/L (September 2014 and March 2015 respectively). BH4 recorded TPH fractions up to the C15-C28 fraction in the September 2014 monitoring round, totalling 0.84 mg/L, but only the C6-C9 fraction (0.15 mg/L) in March 2015. The LEMP provisional limits were exceeded at BH2 and BH4 but remained below the historical maximum values.

Low levels of aluminium were detected at all monitoring stations, with the highest being 0.08 mg/L at BH1 and BH1A in September 2014. This concentration is significantly lower than the 5 mg/L guideline value for livestock drinking water (ANZECC & ARMCANZ, 2000). There is no LEMP provisional limit for aluminium in groundwater; all concentrations were consistent with historical results.

The concentration of copper remained below the LEMP provisional limit of 0.015 mg/L in all samples with the highest concentration of 0.009 mg/L recorded at BH5 (March 2015). All concentrations were consistent with historical ranges, lower than the guideline value for livestock (0.5-5 mg/L, ANZECC & ARMCANZ, 2000) and for human drinking water (2 mg/L, NHMRC & NRMMC, 2011).

Manganese concentrations ranged from below the laboratory LOR of 0.001 mg/L at BH6 (March 2015) to 0.768 mg/L at BH2 (March 2015). The manganese concentration of 0.768 mg/L at BH2 fell outside the established range was the new maximum at the site No values recorded during the reporting period exceeded the conservative human health guideline limit of 0.5 mg/L. There are no livestock drinking water or LEMP provisional limits for manganese.

Concentrations of iron ranged from below the laboratory LOR of <0.05 mg/L at multiple locations, to a maximum of 4.93 mg/L at BH2 (March 2015). All concentrations were consistent with established ranges and all were below the short-term crop irrigation guideline value of 10 mg/L (ANZECC & ARMCANZ, 2000). There is no LEMP provisional limit for iron in groundwater.

In accordance with Section 3.8.2.3 of the LEMP, if monitoring indicates pollution, groundwater in the affected piezometer will be sampled and tested again as soon as possible to confirm the results. If re-sampling confirms the anomaly, the EPA will be notified as soon as practicable after it becomes known, by telephone and in writing within 14 days of confirmation.


ORANGE CITY COUNCIL


While a number of parameters exceeded the LEMP provisional groundwater limits this monitoring period, all levels were generally consistent with historical results, were not considered excessively high or displayed decreases in subsequent monitoring rounds. No increasing adverse trends were observed, therefore re-sampling was not undertaken.

3.3 SURFACE WATER

Surface water quality monitoring consists of sampling at monitoring sites SW3 and SW4 monthly during discharge. Discharge events occurred only in February and April 2015 (SW3 and SW4).

Analytical results for SW3 and SW4 are presented in Appendix A, Tables A4 and A5.

3.3.1 QUALITY

pH in surface water ranged from slightly alkaline in SW3 at 7.53 (February 2015) to moderately alkaline in SW4 at 7.96 (February 2015). These values are within the range recommended as suitable for livestock drinking water (Markwick, 2007).

Electrical conductivity ranged from 580 µS/cm at SW4 (April 2015) to 1,050 µS/cm at SW3 (February 2015). Corresponding total dissolved solids (TDS) concentrations ranged from 389 mg/L to 704 mg/L, and are considered suitable for consumption by the most susceptible livestock category, poultry (<3,000 mg/L, ANZECC & ARMCANZ, 2000).

Total alkalinity ranged from 166 mgCaCO3/L at SW4 (April 2015) to 290 mgCaCO3/L at SW4 (February 2015). All values were below the conservative aesthetic guideline for human drinking water (200 mgCaCO3/L, NHMRC & NRMMC, 2011) and the guideline hardness value for potential fouling of waters (350 mgCaCO3/L, ANZECC & ARMCANZ, 2000).

Sulfate concentrations ranged from 7 mg/L at SW4 (April 2015) to 157 mg/L at SW3 (April 2015). These concentrations are lower than the 1000 mg/L guideline value for livestock drinking water (ANZECC & ARMCANZ, 2000).

Chloride concentrations ranged from 78 mg/L at SW3 (February 2015) to 118 mg/L at SW4 (February 2015). No exceedance of the upper guideline value for irrigation to moderately tolerant crops (700 mg/L, ANZECC & ARMCANZ, 2000) was recorded.

Calcium concentrations were all lower than the livestock drinking water guideline value of 1,000 mg/L (ANZECC & ARMCANZ, 2000). Monitoring station SW3 recorded the highest concentration at 63 mg/L (February 2015), whilst the lowest concentration of 12 mg/L was recorded at SW4 (April 2015). Concentrations were consistent with historical data.

Magnesium concentrations ranged from 17 mg/L at SW4 (April 2014) to 29 mg/L at SW4 (February 2015) and were consistent with historical data.

Potassium concentrations ranged from 27 mg/L at SW4 (April 2015) to 54 mg/L at SW4 (February 2015) and were consistent with historical data.

Sodium concentrations were recorded to be lowest at SW4 at 60 mg/L (April 2015) and highest at SW4 at 86 mg/L (February 2015). These values are below the irrigation guideline for moderately tolerant crops (460 mg/L, ANZECC & ARMCANZ 2000), and the conservative aesthetic guideline for human drinking water (180 mg/L, NHMRC & NRMMC 2011).

Manganese ranged from 0.302 mg/L at SW4 (April 2015) to 1.05 mg/L at SW4 (February 2015). Manganese concentrations were consistently below the short-term (<20 years) crop irrigation guideline value of 10 mg/L (ANZECC & ARMCANZ, 2000). Concentrations were consistent with historical data.

Iron ranged from 0.44 mg/L at SW4 (February 2015) to 3.35 mg/L at SW3 (April 2015). For irrigation purposes, iron concentrations were below short-term (<20 years) irrigation criteria of 10 mg/L (ANZECC & ARMCANZ, 2000) at all locations.


ORANGE CITY COUNCIL


Fluoride concentrations were consistent at 0.2 mg/L and lower than the livestock drinking water guideline value of 2 mg/L (ANZECC & ARMCANZ, 2000) and are consistent historical data.

Ammonia concentrations were recorded up to 14 mgN/L at SW3 (April 2015) which exceeded the aesthetic guideline for ammonia in human drinking water (0.41 mgN/L, NHMRC & NRMMC, 2011). Ammonia concentrations of 1.98 mgN/L at SW3 and 4.04 mgN/L at SW4 in February 2015 also exceeded the aesthetic guideline. The LEMP provisional limit of 1 mgN/L was also exceeded at these locations, however ammonia concentrations were below the historical maximums recorded at each monitoring point.

Nitrate was lowest at 0.02 mgN/L at SW4 (April 2015) and highest at SW3 at 2.49 mgN/L (April 2015). Nitrate concentrations were below the livestock drinking water guideline value of 90.29 mgN/L (ANZECC & ARMCANZ, 2000) and the LEMP provisional limit of 10 mgN/L.

Total phenolics were below the LOR (<0.05 mg/L) at all surface water monitoring points in the reporting period.

3.4 LEACHATE

Leachate quality monitoring consisted of sampling of the leachate pond L2 in the September 2014 and March 2015 sampling rounds.

Analytical results for leachate are presented in Appendix A, Table A2 and A3.

3.4.1 QUALITY

pH in leachate was slightly alkaline and ranged from 7.48 (March 2015) to 7.82 (September 2014). These values are within the range recommended as suitable for livestock drinking water (Markwick, 2007).

Electrical conductivity ranged from 1,730 µS/cm (March 2015) to 2,200 µS/cm (September 2014). Corresponding TDS concentrations ranged from 1,159 mg/L to 1,474 mg/L, below the criteria for consumption by the most susceptible livestock category, poultry (<3,000 mg/L, ANZECC & ARMCANZ, 2000).

Total alkalinity ranged from 451 mgCaCO3/L (March 2015) to 504 mgCaCO3/L (September 2014), exceeding the conservative aesthetic guideline for human drinking water (200 mgCaCO3/L, NHMRC & NRMMC, 2011) and the guideline hardness value for potential fouling of waters (350 mgCaCO3/L, ANZECC & ARMCANZ, 2000).

Sulfate concentrations ranged from 30 mg/L (March 2015) to 31 mg/L (September 2014). These concentrations are lower than the 1000 mg/L guideline value for livestock drinking water (ANZECC & ARMCANZ, 2000).

4.0 OTHER MONITORING DATA

4.1 PUBLIC CONCERNS AND COMPLAINTS

There were seven complaints made to the EPA regarding the operation of the landfill during the annual reporting period. All complaints fell between September 2014 and March 2015 and related to odour. Application of cover material, drying out of wet organic material, closing facility doors, floor washing, daily removal of waste from within the baling facility and use of a probiotic within the misting system addressed these issues.

4.2 SOLID WASTE QUANTITIES

Note: For each ‘Waste Type’, the first number identifies waste tonnage that has been weighed. The second number refers to tonnage estimates using EPA published vehicle weight conversion factors.


ORANGE CITY COUNCIL


The total tonnage received into the landfill for the year ending June 2015 was 20,183.36 t. The total Virgin Excavated Natural Material (VENM) component of this was 8,978.35 t. For licensing purposes, the total waste amount applied to landfill was 11,205.01 t.

It is noted that MRF glass fines are used for access track construction.

The total amount into landfill for 2014/2015 is below the limit set under Licence Condition L5.1, which states that the total tonnage of waste disposed of at the premises must not exceed 65,000 t/annum.

4.2.1 SURVEY VOLUME CALCULATIONS

Detailed survey of the Stage 3 landfill surface was undertaken in June 2014 and July 2015. Data from these surveys was used to create digital terrain models of the landfill for use in volume calculations.

The landfill volume used between the two surveys was determined to be 21,413 m3.

4.2.2 EFFECTIVE COMPACTION

The calculated landfill volume and the recorded waste quantities were used to determine the average waste compaction (excluding cover material) for the landfill. The licence for the facility requires a minimum waste compaction of 0.65 t/m3.

The landfill volume utilised in the period from 16 June 2014 to 7 July 2015 was 21,413 m3. Correcting this volume for the 365 day licensing period, the landfill volume utilised equates to 20,248 m3, which is comprised of 8,978.35 t of VENM, 1,974.03 t of glass fines and 9,230.98 t of waste materials.

Therefore, the average waste compaction for the landfill in the reporting period to 30 June 2015 is 1.00 t/m3. This indicates that compliance with the minimum compaction requirement is being achieved.

4.2.3 Waste Diversion Operations

The approximate proportions of waste streams diverted by sector are shown below:

Building / Demolition: 9,989 t diverted1 of 14,244 t received; 70%

Industrial / Commercial / Not-For-Profit: 5,260 t diverted2 of 14,254 t received; 37%

Residential / Municipal: 19,603 t diverted of 32,851 t received; 60%

Based on the above tonnages, approximately 34,852 t of waste material (of 61,349 t received) is diverted for recycling or on-site landfill operational purposes, equating to approximately 57% diversion.

1 Includes 8,678 t of VENM waste used for operational purposes at ORRRC. 2 Includes 1,974 t of glass fines used for operational purposes at ORRRC.

5.0 SUMMARY

This section provides a summary of the monitoring results presented in Section 3 and Section 4.

5.1 MONITORING

5.1.1 Groundwater

Groundwater monitoring was conducted at six piezometer monitoring stations in September 2014 and ten piezometer monitoring stations in March 2015.

Groundwater levels remained relatively consistent throughout the reporting period, with BH3 remaining the up-gradient monitoring point. Groundwater elevations of recently installed monitoring locations BH5 and BH6 correspond to down-gradient locations.

Groundwater samples were obtained from monitoring stations BH1, BH1A, BH2, BH3, BH4, BH5, BH6 and BH7 and were analysed for the biannual suite of parameters. Monitoring stations BH2A and BH7A could not be sampled as they provided insufficient recharge following purging.

While a number of parameters exceeded the LEMP provisional groundwater limits this monitoring period (e.g. TPH in BH2 and BH4), all levels were generally consistent with historical results, were not considered excessively high or displayed decreases in subsequent monitoring rounds. No increasing adverse trends were observed, therefore re-sampling was not undertaken.

5.1.2 Surface Water

Two discharge samples were collected from SW3 and SW4 during the reporting. Only Ammonia in February 2015 (SW3 and SW4) and April 2015 (SW3) exceeded the LEMP provisional limit, but was consistent with the established range.

Concentrations of monitored analytes in surface water were generally below LEMP provisional limits or within historical ranges.

5.1.3 Leachate

The leachate monitoring point was sampled in September 2015 and March 2015. Concentrations of monitored analytes in leachate were generally within historical ranges.

5.1.4 Landfill Gas

No landfill gas was detected accumulated within buildings located within 250 metres of deposited waste during the reporting period.

5.2 COMPLAINTS

There were seven complaints made to the EPA regarding the operation of the landfill during the annual reporting period. All complaints fell between September 2014 and March 2015 and related to odour. Application of cover material, drying out of wet organic material, closing facility doors, floor washing, daily removal of waste from within the baling facility and use of a probiotic within the misting system addressed these issues.

5.3 SOLID WASTE QUANTITIES

A total of 20,183.36 t of waste (including VENM) was received into the landfill for the reporting period.

The total waste landfilled for licensing purposes was 11,205.01 t. This is below the maximum limit set under Licence Condition L5.1 (65,000 t).


ORANGE CITY COUNCIL


5.4 WASTE COMPACTION AND DIVERSION

The rate of waste compaction was 1.00 t/m3, which was above the requirement of 0.65 t/m3.

In the reporting period, approximately 57% of waste material was diverted for recycling or on-site landfill operational purposes.


ORANGE CITY COUNCIL


6.0 CONCLUSION AND RECOMMENDATIONS

6.1 CONCLUSION

The results of the groundwater and surface water monitoring sampling indicated some minor fluctuations in the conditions at the Ophir Road Resource Recovery Centre. While a limited number of historical ranges and LEMP provisional limits were exceeded, no adverse trends were observed.

No landfill gas was detected accumulated within buildings located within 250 metres of deposited waste during the reporting period.

The total waste landfilled for licensing purposes was 11,205.01 t. This is below the limit set under Licence Condition L5.1. The rate of waste compaction was above the licencing requirement.

6.2 RECOMMENDATIONS

It is recommended that environmental monitoring be continued at the Ophir Road Resource Recovery Centre in accordance with existing monitoring requirements of EPL 5956 and the Ophir Road Waste Management Facility LEMP.

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing purposes.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.

LOR = Limit of reporting

^ = This result is computed from individual analyte detections at or above the level of reporting
