Murrang Earth Sciences performed a detailed site investigation of a site contaminated by a sheep dip in rural ACT. By employing Field-XRF technology as well as standard techniques of sampling and analysis, the investigation rapidly and cost-effectively pinpointed contaminated areas, allowing the scope of work to focus only on where contamination was confirmed to occur. This investigation met both the demands of the regulator and the client, enabling the dreamed-for development to proceed.
