About Enviroscan Industrial & Marine Surveys
Our principal activity involves the testing of air emissions, including odour, noise and hazardous pollutants, to assist process control and for compliance with EPA guidelines. Subsoil contamination and groundwater/stormwater surveys are adjunct activitie

National Pollution Inventory NPI (1999 - 2002)
Dioxin and Furan emissions have been measured from several industrial sites in South Australia using USEPA Method 23 and 23A. Results generally conform with the European standard of 0.1 ng/Nm3.
Samples are analysed by the AgriQuality Dioxin Laboratory at Gracefield, New Zealand. We visit the laboratory regularly to keep up with developments.

Zinc smelter Gas Train Surveys (1998-9)
A gas sampling system was set-up to cope with high dust loadings at temperatures up to 1100°C and velocities to 30m/s. Gas analyses were made by both IR and EC instruments, with data acquired from up to 5 sites spread over 80 metres of ductwork simultaneously.

Large-scale seabed search (1994-5)
A large-scale search was carried out in Gulf St Vincent, South Australia to locate a submerged vessel. Orientation survey on dredge and pontoons sunk off Port Stanvac is shown. The initial search area exceeded 500km2 with water depths ranging to 40 metres. Sidescan sonar coupled with magnetometer was used on a grid search, with a line spacing of 700metres and DGPS navigation to 4metres. A target was located after 120 hours of survey and identified for the client by detailed sonargram.

Oil exploration (1992-9)
Reconnaissance oil exploration surveys have been undertaken using nearsurface geochemical techniques developed in North America and Australia during the 1980s. Some onshore case-histories were published in Severne et al. 1991, Bull. Assoc. Petroleum Geochemical Explorationists. v.7 no. 1 pp.88-115.
Current activity is focussed in South Australian continental shelf waters, primarily screening seismic structures for active microseepage.

Continuous Emission Monitoring System (CEMS)
A portable CEMS unit was brought on-line in 1999. This Horiba PG-250 unit measures NOx, SO2, CO, CO2 and O2 using chemiluminescence and non-dispersive infra-red. It meets all USEPA requirements for backup CEMS. NATA calibration gas standards ensure accuracy and dilution probes cope with wet (>20% moisture) and high (>1%) SO2, high (>20%) CO2 gas streams. Logging is via RS-232C interface to user specification.
