Shire of Wyndham East Kimberley
Hydrogeological Assessment Report – Kununurra Waste Disposal Site (2025)
Preparation of a hydrogeological assessment to meet licence requirements and support ongoing groundwater management at the Kununurra Waste Disposal Site
Assessment of groundwater levels, flow directions and seasonal behaviour using multi year monitoring data collected to Australian Standards
Evaluation of groundwater quality trends against environmental and non potable use guideline values, including QA/QC review of field and laboratory data
Recommendations for continued monitoring and additional infrastructure to improve understanding of upgradient groundwater conditions
ASK Waste Management prepared a comprehensive Hydrogeological Assessment Report for the Kununurra Waste Disposal Site to satisfy groundwater assessment and reporting requirements under the site’s renewed Environmental Protection Licence.
The report documents groundwater conditions beneath and surrounding the landfill, with a focus on groundwater levels, flow directions, seasonal behaviour and groundwater quality trends.
The assessment draws on groundwater monitoring data collected between July 2022 and June 2025, following the transition to qualified external sampling in accordance with Australian Standards. It includes detailed descriptions of monitoring bores, field and laboratory QA/QC procedures, and an evaluation of data reliability.
Groundwater quality results are assessed against relevant environmental and non‑potable use guidelines, with trend analysis used to identify spatial and temporal patterns and potential localised influences.
