ChemCentre, a national lab employs the highest level of scientific expertise and state-of-the-art laboratory instrumentation to investigate and solve a vast array of complex analytical problems. Following community concerns the ChemCentre were called in by the Department of Transport who were operating for the Shire of Busselton to monitor hydrogen sulphide (rotten egg gas) during the removal (by-pass) of seagrass from a local beach.
The GPAC System™ trial ran for a month beginning at the start of May, during this time H2S levels in the range of 0.01 to 1.8 ppm (V) were detected, below the Health Department guidelines of 2 ppm (V).
A chief researcher explained the benefits, “By using the GPAC System™ we were able to monitor real time H2S levels and protect the community by reducing exposure to high level of gas. The automated triggers alerted us to potentially high levels of H2S, enabling us to contact the contractors who were removing the seagrass to alert them to modify their behavior to minimize gas release. As a result, residents were not exposed to H2S levels above Health Department recommendations for the length of the study”.
