On 1 December , BDC submitted their annual compliance report. BDC are required to provide this report on their compliance with the Mining Act The report is currently under review for compliance with Regulation 77 of the Mining Regulations , and may be subject to change.
The report will be made available on this website once it is accepted by the Department for Energy and Mining DEM as complying with Regulation 77 and reporting requirements. The Department for Environment and Water DEW has recently conducted a recapture of dieback data both from the air and on ground in October The data collected is now being analysed to confirm any changes to the extent of dieback, and provide valuable additional information on the health of the mangrove and saltmarsh ecosystems.
This March data classified dieback mapping into mangrove, saltmarsh, bare ground, and water. The data determined the dieback boundary contains approximately 9 hectares of mangrove, 10 hectares of saltmarsh, and nearly 5 hectares of bare, sparsely vegetated, or aquatic ecosystems. The dead mangrove area represents 0. DEM has received a report of a preliminary assessment into planted tree health within the St Kilda township. The assessment identified the health of trees on public land within St Kilda, finding The majority of dead and stressed trees were found in the southern portion of the town.
The preliminary report identifies elevated levels of salt within the soil as a likely contributing factor to poor planted tree health. The underlying cause and timings of these elevated levels are matters that form part of the ongoing investigations, and further updates will be available in due course. The report also identifies the need for more groundwater monitoring to be undertaken in St Kilda to better understand underlying existing groundwater and soil conditions.
Accordingly, DEM and the City of Salisbury are preparing to establish a groundwater monitoring network in the township. The purpose of this network is to monitor salinity and depth to groundwater in the St Kilda township over time; and determine if there is a risk to trees and infrastructure within the town from saline groundwater. This update refers to a range of pond numbers and areas.
The South Australian government continues to monitor activities and environmental conditions in, and adjacent to, the Dry Creek Salt Field and take necessary actions based on the results of this monitoring.
The results of the October groundwater sampling from a section through pond PA6 in Section 2, adjacent St Kilda towards the mangrove boardwalk area are summarised in the graph below. Some previously reported data points have been revised due to an improved calibration factor which better accounts for the effects of density and viscosity. These results indicate that salt flux, hydraulic gradient, and total dissolved solids TDS in this key monitoring location adjacent to Section 2 of the salt field the section closest to the affected St Kilda mangroves have all declined since the previous month.
These declines follow the anticipated increase in these measures since June over winter, and the estimated salt flux to the marsh at this location is now approximately the same as in June The declining trend evident from prior to June is expected to continue in the summer and autumn months.
These are the ponds adjacent to the impacted St Kilda mangrove boardwalk area. This pumping has not removed salt from Section 2 entirely.
However, it has moved brine away from the existing impact area and further south to pond PA The South Australian government continues to closely monitor management of the southern ponds, and assess risk based on data collected from the piezometer network and surface water habitats across the saltmarsh and mangrove area throughout Section 2.
Based on current monitoring, it is not proposed for the government to initiate additional pumping from the southern ponds at this time. Brine from the northern ponds continues to be pumped into the nearby SA Water Bolivar outfall channel north of St Kilda, to dilute the concentration of salt and safely release it back to the marine environment.
This action is being taken as part of BDC's management of the salt field and aims to establish environmental stability for the pond ecosystems for the short-term. Approximately 2. This has returned the salinity in Section 3 to historical operating levels. As part of monitoring of the northern ponds, the South Australian government is aware of erosion in sea walls in Section 3. This issue has not resulted in any loss of brine from the ponds.
BDC has submitted an erosion management plan and is currently implementing a works program for remediation and maintenance of the sea walls. This work has commenced. Government is aware of isolated mangrove impact recently identified at St Kilda.
Community members have also shared their environmental concerns regarding this matter which is acknowledged and appreciated. Due to the sensitivity of the environment and the lengthy recovery period required for ecosystem restoration, it is not unexpected to observe isolated areas of impact within the impacted area. However based on the current monitoring and data, the government does not expect to observe any new significant dieback areas outside the affected area.
The South Australian government has commissioned a study to assess planted tree health within St Kilda. This study commenced on 20 August and is seeking to determine the cause or causes of damage to dead and distressed trees in the town. The study will also provide advice on necessary further action and next steps. It is anticipated the study will be completed in November Findings of the study will be made publicly available.
St Kilda residents were recently provided with a community update regarding Section 2 pond levels, use of the SA Water Bolivar outfall channel, and upcoming vegetation and groundwater programs within the town. An update has been made to analysis of the hydrogeology of the Dry Creek salt fields, and groundwater and salt flow towards the mangroves.
This update is an extension to analyses presented in the 27 August and 5 July updates on this webpage. It broadens these previous analyses to data from July and August this year, with the following findings:.
A copy of the following media statement released by DEM on 1 September is also provided regarding recent activity at the salt fields. The Government regulators have provided Alliance members with the most up-to-date monitoring data and peer-reviewed science, which shows the significant improvements at the site, and outlined why pumping is not recommended adjacent to the impacted mangroves. The best scientific advice is that recent winter rains pose no additional risk to the area, and there is no evidence of any new impacts on the mangroves.
The Government continues to monitor the site, including through its groundwater monitoring network which is showing significant improvements. Over 1. It is expected that salinity will continue to decrease towards historical levels of to parts per thousand in coming months. The size of the area impacted at the St Kilda salt fields and mangroves sites is less than first thought according to the latest scientific assessments released today. Scientific monitoring also shows the site has stabilised with reduced salinity levels, resulting in an overall improvement to the site.
Independently peer-reviewed high-resolution imagery to map the area of impacted mangrove and samphire over time has been able to show that the total impacted area reported in January has been revised down from 45 hectares to 24 hectares. This includes nine hectares of mangrove dieback and 10 hectares of saltmarsh dieback.
The assessment has also shown that there has been no significant increase in dieback between December and July , and that there is high confidence that no major areas of dead vegetation remain undetected. Government agencies continue to monitor the piezometer network and surface water habitats across the saltmarsh and mangrove area.
There is no current evidence of any new leakage or movement of hypersaline groundwater into the saltmarsh following the partial filling of Section 2 ponds from winter rains. The difference in groundwater elevation hydraulic gradient beneath salt pond PA6 the closest pond to the St Kilda visitors centre and the affected mangroves has significantly reduced. A reduction in hydraulic gradient indicates a decreased flow of groundwater and salt from beneath pond PA6 to the mangrove and salt marsh areas.
So there is no indication at this stage that winter rains will cause any further impact to the mangrove area. To June this year, the hydraulic gradient between Pond PA6 and the affected areas of mangroves and saltmarsh was less than half of what it was in November The graph below shows density corrected groundwater heads from the local piezometer network in the vicinity of PA6.
The reduction in hydraulic gradient is shown by the decreasing difference between the red western pond and green marsh wells lines on the graph.
In the winter months, rainfall will likely cause the hydraulic gradient to vary. Further monitoring will be undertaken to confirm salinity trends. It is expected the hydraulic gradient will continue to decline as:. The South Australian Government continues to monitor and assess salinity trends to examine optimal water balance across the ponds to inform future actions to reduce the risks of additional vegetation impacts.
The South Australian government values the efforts that have been taken by the community to maintain attention on this issue. The Government will continue to inform and consult stakeholders as the path to restoration continues. Brine from the Dry Creek Salt Field is being pumped into the nearby SA Water Bolivar outfall channel north of St Kilda, to dilute the concentration of salt and safely release it back to the marine environment.
It aims to establish long-term environmental stability for the pond ecosystems. The pumping of brine is being undertaken by salt field operator BDC as an interim measure until the long-term future of the area is determined. It will:. Using a combination of existing and new infrastructure, brine from the northern portion of the salt field also referred to as Sections 3 and 4 is being pumped to the channel from the southern end of Pond PA5.
The following photos show the process of water movement from the salt field to the channel and into the gulf. The conditions include:. The recommencement of brine discharge in May into the Bolivar channel resulted in the death of some European Carp a species declared noxious under the Fisheries Management Act present within the channel. The dead carp were collected and reused for commercial fertiliser products.
It aims to offset the salt contained within the sea water being pumped into the salt field and should enable the total salt load in the northern ponds to be reduced. Detail from Mackenzie, Murdoch.
