- Submission of Annual Environmental Report
Sand mining currently takes place to the south-east of the licensed area and clay mining takes place to the east of the licensed area. Both mining areas are separate from the licensed area and will continue under the existing development approvals and mining operating licences. Demolition works lead to the generation of a large amount of concrete, brick, sand and other recyclable materials, as well as materials that require removal and final disposal such as asbestos.
Where recycling is not possible, final disposal of the material will be sought from an appropriately licensed DWER facility. The site in question is part of the BDS waste management process, where material can be sorted for reuse, processed into a recycled product, or sent to landfill in accordance with licensing terms. The information contained in this AER shall contain full and complete details required under Terms 37 and 38 of the DWER License.
The license holder must submit an annual environmental report to the general director no later than 28 calendar days after the end of each annual period, in which it is stated to what extent the license holder fulfilled the conditions of this license for the previous annual period."

- Explanation of Current Exceedances
Chloride rose above the 2014 DOH guidelines (250 mg/L) during the September 2021 and March 2022 sampling events, with levels reaching 620 mg/L and 630 mg/L, respectively. Phosphorus was elevated above the ANZECC long-term irrigation value (0.05 mg/L), with results of 0.06 mg/L and 0.14 mg/L during the respective sampling events. Both sampling events reported an exceedance of the ANZECC 2000 Long Term Irrigation for nitrogen (5000µg/L) with levels reaching 63,000µg/L and 6700µg/L respectively.
Phosphorus was elevated above the ANZECC Irrigation Long Term Value (0.05 mg/L) for March 2022 only, with a reported result of 0.09 mg/L. Chloride exceeded DOH 2014 guidelines (250 mg/L) during the September 2021 sampling event, with a reported level of 260 mg/L. There was an exceedance for phosphorus in September 2021 for the ANZECC 2000 long-term irrigation guidelines (0.05 mg/l) with a reported result of 0.06 mg/l, while in March 2022 there was an exceedance for nitrogen for the ANZECC 2000 Long Term Irrigation Guidelines (5000 µg/L) with a reported result of 6900 µg/L.
Finally, phosphorus exceeded the long-term ANZECC 2000 guidelines for irrigation (0.05 mg/L) with a reported result of 0.12 mg/L. Perth groundwater has naturally high concentrations of iron (Hirschberg, 1992), so it is likely that the elevated result seen in March 2022 is a reflection of natural background conditions.
Assessment and Comparison Against Previous Reports
Chloride is one of the most common naturally occurring anions in groundwater (Kelly, et al. 2012; Verma and Kumar Ratan 2020) and can be derived from numerous natural and anthropogenic sources including natural mineral deposits, seawater intrusion, discharges agricultural or irrigation, urban. effluents or sewage and industrial effluents (Brandt, et al. 2017). The ion is readily mobile in groundwater and cannot be removed through biological (Hunt, et al. 2012) or conventional water treatment processes (Brandt, et al. 2017). The presence of animal manure as well as the application of fertilizers can cause an increase in nitrogen and phosphorus levels in the surrounding area.
Borehole BP has historically been dry, with no samples likely to be taken in September 2021, or in the previous monitoring year. The pH was measured for each sample collected in the field, and then retested in the laboratory. The low pH can probably be explained by the lack of alkaline substances in the groundwater system (Zhou et al. 2015), or the presence of organic matter (Ritchie and Dolling 1985).
The reported concentration of chloride from Bore GB has fluctuated above and below the DOH 2014 guideline across the sampling events. The field results vary between below the range and within the range, but also show no clear trends.

Calibration of Equipment
Anions - a series of anions are determined by Ion Chromatography based on APHA latest edition Method 4110-B. Ion balance calculation: Cations in water by ICP-OES; Anions in water by IC; Alkalinity in water by Titration with APHA methods. It consists of either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class.
The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine if there are any matrix interferences. This is the component of the analytical signal that does not come from the sample but from reagents, glassware, etc. can be determined by processing solvents and reagents in exactly the same way as for samples. Samples for microbiological analysis (not Amoeba forms) received outside the temperature range of 2-8°C do not meet the ideal refrigeration conditions stated in AS2031-2012.
Where sampling dates are not provided, Envirolab is unable to comment on the validity of the analysis where the recommended technical retention time may have been breached. Please note that results for water analysis can only be indicative, as the analysis may be carried out outside the recommended APHA holding times.
