SUBJECT Ipswich Void Characterisation

The void located on BMI’s site at the Ipswich Resource Recovery Centre has filled from surface water runoff and, to a lesser extent, groundwater infiltration from the surrounding region over many years. To allow the repurposing of the void, BMI propose to dewater it to Six Mile Creek (SMC), which runs past the eastern side of the void. In support of the assessment of this activity, a comprehensive characterisation of the void water quality has been conducted to identify any parameters which may potentially require treatment prior to discharge to the receiving environment. Note that previous sampling was deemed to be insufficient to reliably represent the water quality across the void. On Friday the 27th of July 2018 Wastewater Futures conducted extensive characterisation sampling and analysis of the void water. The characterisation was designed to meet the requirements of Items 4 & 5 from the Austin St RFI issued by the State Assessment and Referral Agency (SARA) in March 2018. In-situ measurements were taken within the void and samples were sent to ALS laboratories for analysis. The results indicated that there was very little variation in the water quality across the void and that the water quality overall was good. Some parameters (ammonia, NOx, total nitrogen, dissolved oxygen and boron) were marginally outside of the guideline trigger values in the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (2000). However, these were either below the levels observed in Six Mile Creek (ammonia, NOx and total nitrogen) and/or at levels which would be addressed upon discharge (dissolved oxygen). Although the water quality was good in the void, a treatment plan has been proposed to increase the dissolved oxygen (DO) levels upon discharge, which essentially involves creating turbulent flow to oxygenate the water to the appropriate levels. Sampling Methodology A small boat was used to access the void and a depth sampler (for depths of up to 30 m) was used to collect samples at various depths below the surface. Calibrated hand-held meters were used for the in-situ measurements in accordance with DES sampling guidelines. In-situ measurements were taken at three depths across six evenly-spread sample locations in the void. The sample depths (0 to 2 m, 10 m and 20 m) and locations were selected to ensure that any variation in the water quality with depth or region of the void were identified. Note that an additional sample was collected from Location 6 at a depth of 30 m. Due to the low level of variation observed in the in-situ measurements only samples from locations 1, 2 and 6 were sent for laboratory

Discussion Overall, the water quality in the void was good. Table 3 below shows a summary (average and maximum values) of the total metal results and other significant parameters, including those which have guideline trigger values in the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (2000). Referenced in the table are the 95% level of protection (LoP) trigger values for metals and the regional guideline values for slightly to moderately disturbed upper estuarine environments in south-east Queensland. A summary of the results from the recent sampling conducted in Six Mile Creek (SMC), the proposed discharge body, have also been included in the table for comparison. The extended set of SMC results are shown in the appendix. Results which exceeded the guideline trigger values have been highlighted. Note that there was no relevant trigger value for EC, which was identified as being elevated.

1. Dissolved Oxygen 2. pH 3. Electrical Conductivity 4. Total Boron 5. Nitrogen (ammonia, NOx & total nitrogen)




Dissolved Oxygen: The DO levels recorded in the void (from 43 to 61% saturation) were good for a still body of water and were very similar to the SMC levels (50 to 69%). However, since the DO was below the default trigger values (80 to 105%), the dewatering system will be designed to increase the DO in the discharged water to saturation levels, i.e. approximately 100%. Based on the DO levels in the void, pumping alone may be sufficient to boost DO to within the target range. Additionally, water will be discharged via a flow-through chamber designed to create turbulence and increase DO to the target level. Electrical Conductivity: The average EC in the void water (3,400 µS/cm) was higher in comparison to the average EC in SMC (1,840 µS/cm). However, the EC during the February 2018 sampling event was low due to a high flow rainfall event. Excluding the readings collected during the rainfall event, the EC in the void water was only marginally higher than the EC in SMC (2,850 µS/cm). Therefore, the change to the EC in SMC as a result of the void water discharge would be relatively small. Boron: In general, the metal concentrations in the void water were low. Boron was the only species with a void water concentration (0.38 to 0.39 mg/L) slightly higher than the 95% trigger value (0.37 mg/L). However, the boron concentration was significantly lower in comparison to the 90% trigger value (0.68 mg/L). Since the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (2000) state that the 95% LoP trigger value is considered sufficient to protect slightly to moderately disturbed ecosystems, it could reasonably be expected that the boron levels in the void water, which are only very marginally above this level, would not have a significant impact on the receiving body. Nitrogen: The nitrogen levels in the void water were above the guideline values for slightly to moderately disturbed estuaries in south-east Queensland. However, it should be noted that the nitrogen levels are significantly lower than the levels that could be achieved in most wastewater treatment plants, with Best Practice nutrient removal plants achieving TN < 3 mg/L (TN in void water 0.5 – 0.9 mg/L). Several such plants exist in this catchment with discharges to the Bremer River, Bundamba Creek and Sandy Creek. Furthermore, the potential for eutrophication due to slightly elevated nitrogen levels would be limited since no phosphorus is present in the void water (<0.01 mg/L as TP).

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

ø = ALS is not NATA accredited for these tests.

~ = Indicates an estimated value.

Amendment (09/08/2018): This report has been amended and re-released to allow the reporting of additional analytical data. The specific data include total and dissolved metals as per ALS 15 Metals suite (W3

and W3T).

l

It is recognised that EG020-T (Total Metals by ICP-MS) is less than EG020-F (Dissolved Metals by ICP-MS) for some samples. However, the difference is within experimental variation of the methods.l

EA016: Calculated TDS is determined from Electrical conductivity using a conversion factor of 0.65.l

Sodium Adsorption Ratio (where reported): Where results for Na, Ca or Mg are <LOR, a concentration at half the reported LOR is incorporated into the SAR calculation. This represents a conservative approach

for Na relative to the assumption that <LOR = zero concentration and a conservative approach for Ca & Mg relative to the assumption that <LOR is equivalent to the LOR concentration.
