ESdat environmental data management for groundwater contamination

Supplier News

ESdat Environmental Data Management Software has been used for the management and reporting of large datasets generated from groundwater contamination investigation on an industrial facility in Adelaide.

ESdat environmental data software was used to manage site data as well as maintain conceptual model and time series outputs at the complex site over an extended period.

Developed by Earth Science Information Systems (EScIS) as a specialist environmental database management system, ESdat is used by environmental consultants and site managers associated with contaminated/ industrial sites, groundwater investigations, landfill and regulatory compliance.

An ongoing investigation and remediation program has been conducted since 1999 at the Adelaide-based industrial facility as a result of TCE leakages and the subsequent groundwater contamination.

The program comprised of site characterisation and remediation including borehole drilling, well installation monitoring, soil, groundwater and vapour sampling, laboratory analysis and preliminary in-situ chemical oxidation (ISCO) of impacted media.

Over 30 soil bores and 50 monitoring wells have been installed to date, both on and off site, with six groundwater monitoring events carried out since 2002. Two shallow aquifers have been impacted beneath the site, the first located at 3-5 metres below ground level (mbgl) and the second at 8-13 mbgl.

ESdat environmental data management software was employed to efficiently manage the large dataset as well as enable efficient production of the required tables, graphs, 3D models, GIS, and other outputs required for conceptual model development.

The contaminated site data management system was used to develop a rigorous conceptual model of the site and the degradation processes occurring, with a combination of chemistry output tables, trend graphs, GIS based maps, and 3D geological and contaminant models.

Once the remediation program began, these graphical, tabular and 3D outputs were continually updated to incorporate the latest data and demonstrate the effect of the remediation to both technical and non-technical audiences.

All historical chemistry and geological data was loaded into ESdat while ongoing chemical and QA data were directly imported from the laboratory generated electronic deliverables resulting in an accessible, consolidated and consistent data set.

The system also enabled ready visualisation of the underlying sequences of sands and clays in three dimensions while correlation with chemistry data allowed a more detailed analysis of pilot trial results and rebound. This knowledge facilitated the installation of a more accurately targeted injection system for full scale remediation.

ESdat environmental data management software integrates best-of-breed software applications with a managed dataset to produce an insightful site analysis.

ESdat’s ability to readily provide updated outputs in a clear visual format also facilitated improved communication and engagement with both client and regulator.
