iEnvi was engaged by a Council north of Brisbane, QLD, to review environmental authority (EA) compliance, groundwater trends and risks at five landfill sites.
A comprehensive data compilation and transformation was undertaken, along with a data quality review.
Statistical analysis of the data was completed including the basic statistics (average, minimum, maximum, 80th and 120th percentile), geochemical water characterisation using Piper diagrams, statistical significance using the t-test and calculation of correlation coefficients (or similar) for the various parameters in groundwater and surface water:
- To establish the background water level and water quality for each monitoring bore
- To assess the difference between upgradient and downgradient groundwater and surface water characteristics
- To compare each groundwater monitoring point data to leachate and surface water data and surface water dam data to leachate data
- To identify trends (increase or decrease) in of chemical parameters in surface water, groundwater and leachate.
- To define indicators of leachate influence on groundwater and surface water, and interactions between each.
- To record the basic statistics for each monitoring point.
iEnvi identified the impact of the site activities to surface and groundwater understanding that risk-based approach must be used in all aspects in landfill operation in accordance with Guideline Landfill siting, design, operation and rehabilitation (Queensland Government, 2013). The data was presented in reports and data visualisation user Surfer software in drawings.
Recommendations were provided to Council in meetings and the reports and drawings of findings and changes to chemical parameters and groundwater levels over time and higher risk components to focus on for each landfill, and recommendations for risk mitigation.
